Abstract

On an outer casing mounting section (13) of a drum housing (5), there are an accommodation section (75), an engagement claw (81), and a positional regulation member (77). The accommodation section (75) is able to receive an end cap (53) provided to a second end (52) of an outer casing (33). A claw member (76) can be displaced among an engagement position at which the engagement is possible with an engagement step (54) of the end cap (53) that is accommodated in the accommodation section (75), an engagement release position at which the state of engagement is released, and an insertable position at which it becomes possible to insert the end cap (53) into the accommodation section (75). The positional regulation member (77) abuts against an outer peripheral surface of the outer casing (33) when the outer casing (33) has been inclined in the state where the end cap (53) is accommodated in the accommodation section (75), and therefore it is easy to mount a long cylindrical member onto a mounting target and is possible to suppress falling off of the long cylindrical member from the mounting target.

Description

Mounting structure for cylindrical elongated members

The present invention relates to a mounting structure for a cylindrical elongated member, and a window regulator using the mounting structure.

For example, there is a window regulator that uses a structure in which a cylindrical long member is attached to an attachment target. The window regulator is a device that raises and lowers a window glass attached to a window opening of a vehicle. The window regulator includes a carrier plate attached to the lower end portion of the window glass, an inner cable that raises and lowers the carrier plate, and a drive unit that drives the inner cable. The drive unit includes a drum that winds and feeds the inner cable, a drum housing that rotatably supports the drum, and a drive motor that rotationally drives the drum, and these are integrated with the door panel. It is attached.

The inner cable has one end connected to the drum, hung around a cable guide attached to the door panel, and the other end connected to the carrier plate. By rotating the drum by a drive motor, the carrier cable is moved up and down by winding the inner cable around the drum or feeding it from the drum.

A so-called railless window regulator is known in which a guide rail that slides and guides the carrier plate along the window glass ascending / descending direction is not provided. In this window regulator, an outer casing that covers the inner cable that moves in the axial direction by the rotation of the drum between the drum housing and the cable guide may be used.

As an attachment structure for attaching such a cylindrical elongate member such as an outer casing to an attachment target such as a drum housing or a cable guide, for example, as described in Patent Document 1, a single-stage locking is provided on the drum housing to be attached. And a casing cap fixed to the tip of the outer casing of the cylindrical long member is locked by a locking piece.

JP 2009-299429 A

In the mounting structure of the cylindrical long member of Patent Document 1, the tip of the outer casing can be easily detached from the outer locking portion due to a load during inspection or mounting on the door panel. It is easy to come off from the mounting object such as a guide. In order to prevent this, if the fitting between the casing cap and the locking piece is strengthened to make it difficult to come off, the engagement between the locking piece and the casing cap becomes too hard. It becomes difficult to insert it into the joint, making it difficult to attach to the attachment object. Moreover, in order to make it easy for the casing cap to be inserted into the fitting portion of the attachment object and to make it difficult for the casing cap to come off, it is necessary to establish an appropriate engagement state with the casing cap, and high dimensional accuracy is required. So difficult to manufacture. That is, as a structure for attaching the long member to the attachment target, an attachment structure in which the attachment work is easy and the long member is not easily detached is desirable.

The subject of this invention is providing the attachment structure of the elongate member which can be easily attached to the attachment object of a cylindrical elongate member, and can suppress that a cylindrical elongate member remove | deviates from an attachment object. .

Hereinafter, a plurality of modes will be described as means for solving the problem. These aspects can be arbitrarily combined as necessary.

The attachment structure of the tubular long member according to the aspect of the present invention is an attachment structure for attaching the tubular long member to an attachment object. A cylindrical elongate member has an engaging part engaged with attachment object. The attachment target includes an accommodating portion, an engaged portion, and a position regulating member. The accommodating part can receive the engaging part. The engaged portion includes an engagement position that can be engaged with the engagement portion accommodated in the accommodation portion, an engagement release position where the engagement state with the engagement portion is released, and a relationship between the cylindrical elongated member. The joint portion can be displaced between an insertable position where the joint portion can be inserted into the housing portion. The position restricting member engages the engaged portion when the tubular long member positioned outside the housing portion is inclined while the engaging portion is housed in the housing portion. The position of the cylindrical elongated member is regulated so as not to be displaced to the release position. According to this configuration, when the engaging portion of the tubular long member is attached to the attachment target, the engaging portion of the tubular long member displaces the engaged portion to the insertable position, so that attachment is easy. become. Furthermore, after the engaging portion of the cylindrical long member is accommodated in the accommodating portion to be attached, the cylindrical elongated member is unlikely to come out of the attaching subject because the engaging portion engages with the engaged portion. . Furthermore, when the tubular long member is inclined, the position restricting member restricts the position of the tubular long member, so that the engaged portion is not displaced to the disengagement position. As a result, since the engaged portion is prevented from being displaced to the disengagement position due to the swinging of the cylindrical long member, the cylindrical long member is difficult to come out of the attachment target.

The attachment structure of the cylindrical long member further includes a retaining mechanism for restricting the distal end portion of the cylindrical long member from coming out of the accommodating portion on the side opposite to the engaged portion with respect to the axis of the accommodating portion. Can do. In this case, it is possible to suppress the tubular long member from being pulled out of the accommodating portion to be attached by the position regulating member and the retaining mechanism.

The engaged portion may be an engaging claw that can be engaged with the engaging portion. In this case, the attachment structure further includes a leaf spring member that urges the engagement claw toward the engagement position that engages the engagement portion. The leaf spring member constitutes a part of the housing portion. In this case, the leaf spring member bends to facilitate the attachment of the tubular long member to the attachment object, and the leaf spring member biases the engagement claw toward the tubular long member, And the step formed on the tip of the tubular long member can be reliably engaged, and the attachment object and the tubular long member can be reliably engaged. Further, since the leaf spring member constitutes a part of the housing portion, it is not necessary to provide a wall portion corresponding to the leaf spring member constituting the housing portion, and therefore the housing portion can be made small.

A window regulator according to another aspect of the present invention includes a carrier plate, an inner cable, a cable guide, a drum, a drum housing, and an outer casing. The carrier plate holds the window glass. One end of the inner cable is connected to the carrier plate and pulls the carrier plate in a predetermined direction. The cable guide changes the direction of the inner cable. The other end of the inner cable is connected to the drum, and the inner cable wound around the cable guide is taken up and fed out. The drum housing rotatably supports the drum. The outer casing covers the inner cable located between the cable guide and the drum housing. The outer casing has an engaging portion that engages with the drum housing. The drum housing includes a housing portion, an engaged portion, and a position regulating member. The accommodating part can receive the engaging part. The engaged portion includes an engagement position that can be engaged with the engagement portion accommodated in the accommodation portion, an engagement release position where the engagement state with the engagement portion is released, and a distal end portion of the outer casing. It can be displaced between the insertable position where it can be inserted into the part. The position regulating member prevents the outer casing from displacing the engaged portion to the disengaged position when the outer casing positioned outside the accommodating portion is inclined with the engaging portion being accommodated in the accommodating portion. In addition, the position of the outer casing is regulated. According to this structure, when attaching the front-end | tip part of an outer casing to the accommodating part of a drum housing, since the engaging part of an outer casing displaces a to-be-engaged part to an insertion possible position, attachment becomes easy. Furthermore, after the engaging portion of the outer casing is accommodated in the accommodating portion of the drum housing, the outer casing is unlikely to come out of the accommodating portion of the drum housing because the engaging portion engages with the engaged portion. Further, when the outer casing is tilted, the position restricting member restricts the position of the outer casing, so that the engaged portion is not displaced to the disengagement position. As a result, it is difficult for the outer casing to come out of the housing portion of the drum housing.

In the attachment structure of the cylindrical long member according to the present invention, it is easy to attach the cylindrical long member to the attachment target, and the cylindrical long member can be prevented from being detached from the attachment target. Moreover, in the window regulator which concerns on this invention, it becomes possible to attach easily the outer casing which is a cylindrical elongate member to the drum housing which is attachment object, and can suppress that an outer casing remove | deviates.

Also good. The end piece 41 is accommodated in the end accommodating portion 21 of the carrier plate 2 in a state where the end piece 41 is attached to the spring attaching portion 43 to the coil spring 44.

The other end of the ascending cable 31 is provided with an end piece 45 for drum attachment that is accommodated in an end accommodating portion (not shown) provided in the drum 4. The end piece 45 has, for example, an outer diameter larger than the outer diameter of the lifting cable 31 and is made of, for example, a metal material, a hard synthetic resin, or other materials. The end piece 45 is attached to the tip of the ascending cable 31 by a fixing method such as adhesion, welding, caulking, or may be formed by die casting, and is fixed to a predetermined position of the drum 4.

The outer casing 33 has a first end 51 connected to the cable guide 15 and a second end 52 connected to the drum housing 5. The outer casing 33 is a cylindrical long member having an internal hollow, and the raising cable 31 is inserted into the internal hollow. In the illustrated example, the outer diameter of the first end portion 51 is the same as the outer diameter of the cylindrical elongated portion of the outer casing 33. The second end 52 has an outer diameter larger than the outer diameter of the cylindrical elongated member of the outer casing 33, and a cylindrical end cap 53 is attached thereto. The end cap 53 can be integrally formed of the same material as that of the outer casing 33, and can be attached by bonding, welding, caulking, or the like made of the same material or different materials. is there.

An engagement step portion 54 is formed at the joint portion between the end cap 53 and the outer casing 33 based on the difference in outer diameter. The engagement step portion 54 is a step portion formed by the peripheral surface of the outer casing 33 and the upper surface portion 53a of the end cap 53, and constitutes an engagement portion that engages with an engagement claw 81 to be described later. The engaging portion only needs to be able to restrict the outer casing 33 from coming off in the axial direction by being engaged with the engaged portion when the engaging portion is accommodated in the accommodating portion 75. An opening communicating with the hollow of the outer casing 33 is formed at the radial center of the lower surface portion 53b of the end cap 53, and the ascending cable 31 inserted into the outer casing 33 is passed through this opening. Pulled out to the drum 4 side. In the outer casing 33, the first end 51 is inserted into the mounting portion 62 (FIG. 1) of the cable guide 15 and the second end 52 is connected to the drum housing 5 in a state where the rising cable 31 is inserted into the hollow inside. By being inserted into the outer casing mounting portion 13, the drum housing 5 and the cable guide 15 are fixed.

FIG. 3 is a partial cross-sectional view showing a mounting structure between the outer casing 33 and the cable guide 15. The attachment portion 62 of the cable guide 15 has an insertion hole 63 into which the first end portion 51 of the outer casing 33 can be inserted. The insertion hole 63 has an inner diameter that is substantially the same as or slightly smaller than the outer diameter of the outer casing 33, and the first end 51 of the outer casing 33 is press-fitted therein. For example, the first end 51 of the outer casing 33 is inserted into the insertion hole 63 with a pressure equal to or higher than a predetermined pressure, and is fixed to the cable guide 15 by the frictional force between the outer peripheral surface of the outer casing 33 and the inner peripheral surface of the insertion hole 63. Is done. As a modification, the first end 51 of the outer casing 33 may be bonded to the cable guide 15 by applying an adhesive to the outer peripheral surface when the first end 51 is inserted into the insertion hole 63 of the cable guide 15.

The cable guide 15 is formed with a cable insertion hole 64 continuous with the insertion hole 63. The cable insertion hole 64 is inserted through the lifting cable 31 and guides the lifting cable 31 toward the guide member (not shown).

4 is a rear view of the drum housing 5, FIG. 5 is a plan view of the drum housing 5, and FIG. 6 is a sectional view taken along line VI-VI in FIG. The drum housing 5 is formed integrally with the drive unit mounting bracket 11 that is mounted on the door panel, and has a drum housing portion 71 and a support shaft 72 that rotatably supports the drum 4 at the center. The drum housing 5 also includes a lowering cable guide portion 73 that guides the lowering cable 32 to the drum 4, and a rising cable guide portion 74 that guides the rising cable 31 to the drum 4. The end piece 45 of the ascending cable 31 is attached to an end accommodating portion 46 provided on one end face in the axial direction of the drum 4. Similarly, an end piece (not shown) of the lowering cable 32 is attached to an end accommodating portion (not shown) provided on the other end surface in the axial direction of the drum 4.

The drum housing 5 has an outer casing attachment portion 13 to which the second end portion 52 of the outer casing 33 is attached. The outer casing mounting portion 13 includes a housing portion 75 that houses the end cap 53 of the outer casing 33, a claw member 76 that prevents the end cap 53 from coming off, and a position regulating member 77.

The accommodating portion 75 is configured to be able to accommodate the end cap 53, has an inner diameter that is substantially the same as the outer diameter of the end cap 53, and is a cylindrical space that is longer than the axial length of the end cap 53. The accommodating portion 75 can accommodate the end cap 53 so as to be slidable in the axial direction. The accommodating portion 75 is continuous with the ascending cable guide portion 74. The ascending cable 31 drawn out from the opening provided at the tip (lower surface part 53 b) of the end cap 53 is guided to the drum 4 side via the ascending cable guiding part 74.

The end cap 53 accommodated in the accommodating portion 75 is engaged with an engaging claw 81 that functions as a retaining member. The engagement claw 81 is an engagement position that can be engaged with the engagement portion accommodated in the accommodation portion, an engagement release position where the engagement state with the engagement portion is released, and the engagement of the cylindrical elongated member. It is an example of the to-be-engaged part which can be displaced between the insertion possible positions where a joint part becomes insertable in a accommodating part. The engagement claw 81 has an abutment surface 83 that can abut against the engagement step portion 54 of the end cap 53 accommodated in the accommodation portion 75 in the axial direction. The engagement claw 81 is in the engagement position in FIGS. 4 to 6 and can be engaged with the end cap 53. The engagement position is a position at which the outer casing 33 is restricted from moving in the axial direction of the housing portion 75 by the engagement claw 81. The claw member 76 is formed integrally with the drum housing 5 and has an engagement claw 81 and a leaf spring member 82. The leaf spring member 82 is an elastic member erected from the bottom 79 side of the accommodating portion 75 and constitutes a part of the accommodating portion 75. More specifically, the leaf spring member 82 constitutes a part of the inner peripheral wall surface of the accommodating portion 75. The leaf spring member 82 biases the engagement claw 81 toward the engagement position where the engagement claw 81 is engaged with the engagement step portion 54 of the end cap 53 accommodated in the accommodation portion 75. Therefore, the engagement between the engagement claw 81 and the engagement step portion 54 is ensured. Note that the engaging claw 81 may be in the engaging position in a state where the elastic force of the leaf spring member 82 is not acting. The leaf spring member 82 is attached so as to bias the end cap 53 and / or the engaging claw 81 so that the engaging claw 81 as the engaged portion can be engaged with the end cap 53. You may provide in the drum housing which is object.

At the front end of the engaging claw 81, a guide surface 84 that is inclined so as to approach the axis of the accommodating portion 75 is formed. When the end cap 53 is inserted into the housing portion 75, the tip end portion of the end cap 53 comes into contact with the guide surface 84 of the engagement claw 81, and the engagement claw 81 is resisted against the elastic force of the leaf spring member 82. Displace to the insertable position. Therefore, the engagement claw 81 can be easily displaced to the insertable position, so that the outer casing 33 can be easily inserted into the drum housing. The disengagement position of the engagement claw 81 is a position where the contact between the contact surface 83 of the engagement claw 81 and the engagement step portion 54 of the end cap 53 is released by the displacement of the engagement claw 81. For example, when the outer casing 33 is inclined, the engagement step portion 54 can be moved to the outside of the housing portion 75 beyond the contact surface 83 of the engagement claw 81.

The housing portion 75 has a fixed claw 85 at a position facing the engaging claw 81 in the radial direction. The fixing claw 85 is a retaining mechanism that restricts the distal end portion of the tubular long member from slipping out of the housing portion 75 at a position opposite to the engaged portion at a position opposite to the axis X of the housing portion 75. It is an example. The fixed claw 85 is formed integrally with the drum housing 5, and, similarly to the contact surface 83 of the engagement claw 81, the end claw 85 is connected to the engagement step portion 54 of the end cap 53 accommodated in the accommodation portion 75. 53 has an abutting surface 86 capable of abutting in the axial direction. The fixed claw 85 is formed at a position facing the claw member 76 in the radial direction, as shown in FIG. When the outer casing 33 displaces the engaging claw 81 toward the disengagement position in the housing portion 75, the fixed claw 85 is supported by the outer casing 33 so as to come out of the housing portion 75 of the outer casing 33. Any shape that engages with the engaging step portion 54 of the end cap 53 at a position facing the engaging claw 81 may be used, and one or more claw-shaped members are intermittent in the circumferential direction. It can be set as the structure provided. The fixing claw 85 is fixed to the drum housing 5 while the engaging claw 81 is movable, and is provided in the drum housing 5 so as to further improve the suppression of the end piece 45 from coming off.

A guide surface 87 that is inclined so as to approach the axis X of the housing portion 75 is formed at the distal end portion of the fixed claw 85. By inserting the tip of the end cap 53 along the guide surface 87, the end cap 53 is inserted toward the engagement claw 81. Therefore, since the end cap 53 is inserted into the accommodating portion 75 while displacing the engagement claw 81 to the engagement release position, the insertion becomes easy. An insertion opening 78 having an inner diameter larger than that of the accommodating portion 75 is formed on the distal end portion of the fixing claw 85 and the axially outward direction of the engaging claw 81. The insertion opening 78 includes a guide surface 87 of the fixed claw 85 and a position restricting member 77 provided at a position facing the guide surface 87.

The position restricting member 77 is engaged with the tubular long member when the tubular long member positioned outside the housing portion is bent or displaced in a state where the engaging portion is housed in the housing portion. It is an example of the position control member which performs position control of a cylindrical elongate member so that a joint part may not be displaced to an engagement release position. The position regulating member 77 is provided on the outer side in the axial direction of the claw member 76. Further, as shown in FIG. 5, the position restricting member 77 is located on the outer side in the vertical direction with respect to the axis X direction of the housing portion 75 that is the same as the claw member 76 when viewed from the housing portion 75 in a plan view. That is, the position regulating member 77 is opposed to the distal end portion of the fixed claw 85 in the radial direction with respect to the housing portion 75. Therefore, the position restricting member 77 is protruded on the outer casing 33 side attached to the drum housing 5. The front end 77 a of the position regulating member 77 in the direction perpendicular to the axis X direction of the accommodating portion 75 is close to the peripheral surface of the outer casing 33 attached to the drum housing 5. With this structure, when a force that can be displaced toward the claw member 76 acts on the outer casing 33, the outer casing 33 prevents the engagement claw 81 of the claw member 76 from being displaced to the disengagement position. 33 position restriction is performed. Specifically, when the outer casing 33 is to be displaced toward the claw member 76 side, the outer casing 33 is brought into contact with the position regulating member 77 and is not further inclined and displaced. Therefore, the claw member 76 is prevented from being displaced to a position where the end cap 53 and the engagement claw 81 can be disengaged, and the outer casing 33 is prevented from being detached from the housing portion 75.

For example, in FIG. 6, when the outer casing 33 located outside the housing portion 75 is moved in the left direction in the figure, the outer peripheral surface of the outer casing 33 that is in contact with the engaging claw 81 is the engaging claw 81. Is moved to the left. At this time, the movement of the outer casing 33 is restricted by the inner peripheral surface (tip 77 a) of the position restricting member 77 positioned outside the engaging claw 81 being in contact with the outer peripheral surface of the outer casing 33. Therefore, even when the outer casing 33 displaces the claw member 76, the engagement claw 81 does not reach the disengagement position where the engagement with the engagement step portion 54 of the end cap 53 is released.

When the outer casing 33 is displaced, the position restricting member 77 contacts the outer peripheral surface of the outer casing 33 before the engagement state between the engagement step portion 54 of the end cap 53 and the engagement claw 81 is released. It only has to be in touch. Therefore, the arrangement and shape of the position regulating member 77 are not limited to the above embodiment. The position restricting member 77 only needs to be displaceable to the position where the engaging claw 81 can be inserted when the end cap 53 is accommodated in the accommodating portion 75.

In the present embodiment, end pieces provided at one end of the ascending cable 31 and the descending cable 32 are attached to the end accommodating portions 21 of the carrier plate 2 in a state where the ascending cable 31 is inserted into the outer casing 33, End pieces provided at the other end are respectively attached to the drum 4. At this time, the ascending cable 31 is routed so that a position away from the drum 4 by a predetermined distance is wound around the cable guide 15.

Next, the first end portion 51 of the outer casing 33 is inserted and fixed to the attachment portion 62 of the cable guide 15 with a predetermined pressure. Further, the second end portion 52 of the outer casing 33 is attached to the outer casing attachment portion 13 of the drum housing 5. When attaching the second end portion 52 of the outer casing 33, the end cap 53 is inserted into the accommodating portion 75 in an inclined state along the guide surface 87 of the fixing claw 85.

FIG. 7 is an explanatory view showing a process of attaching to the drum housing of the outer casing. When attaching the second end portion 52 of the outer casing 33 to the outer casing attachment portion 13 of the drum housing 5, the distal end portion of the end cap 53 presses the guide surface 84 positioned at the distal end of the claw member 76 radially outward. Meanwhile, the end cap 53 is inserted into the accommodating portion 75. As a result, the engagement claw 81 is displaced to the engagement release position against the elastic force of the leaf spring member 82, and the end cap 53 can be accommodated in the accommodation portion 75.

When the end cap 53 is inserted to a position where the end cap 53 is completely accommodated in the accommodating portion 75, the end cap 53 comes into contact with or close to the inner peripheral surface of the accommodating portion 75, and the engaging claw 81 is moved to the leaf spring member 82. Due to the elastic force, the end cap 53 is displaced to the engagement position where it can engage with the engagement step portion 54 (FIG. 6). At this time, the abutment surface 83 of the engagement claw 81 and the abutment surface 86 of the fixed claw 85 are in a state where they can abut on the engagement step portion 54 of the end cap 53. Therefore, even when the outer casing 33 is pulled from the outside and the end cap 53 slides in the housing portion 75 toward the outside in the axial direction, the engagement step portion 54 is fixed to the contact surface 83 of the engagement claw 81 and the fixed portion. It is prevented from coming off while engaged with the contact surface 86 of the claw 85.

Further, when the outer casing 33 is displaced obliquely outside the housing portion 75, the claw member 76 is pushed against the outer peripheral surface of the outer casing 33 and engaged against the elastic force of the leaf spring member 82. The claw 81 may be displaced. FIG. 8 is an explanatory view showing a state in which the outer casing 33 is bent in the radial direction. As shown in FIG. 8, even when the outer casing 33 is bent toward the claw member 81 in the radial direction outside the housing portion 75, the position regulating member 77 contacts the outer peripheral surface of the outer casing 33. Touch. Thus, the engaging claw 81 is not displaced to the disengaged position where the engaged state with the engaging step portion 54 of the end cap 53 is released. That is, the second end 52 of the outer casing 33 is not detached from the drum housing 5.

(3) Modification (A) It is possible to provide the end cap 53 at the first end portion 51 of the outer casing 33 and provide the configuration of the outer casing mounting portion 13 in the above-described embodiment on the cable guide 15 side. In this case, the second end portion 52 of the outer casing 33 can be configured to be inserted into a mounting portion provided in the drum housing 5 with a predetermined pressure.
(B) It is also possible to provide end caps 53 on both the first end 51 and the second end 52 of the outer casing 33. In this case, the configuration of the outer casing attachment portion 13 can be provided on both the cable guide 15 and the drum housing 5.

The present embodiment can be applied to various types as long as a long cylindrical member such as an outer casing in a hollow is attached to an attachment target such as a drum housing. For example, the present invention can be applied to a control cable for performing opening / closing control of a sliding door, a bonnet, a trunk, a fuel tank lid and the like of a vehicle. Further, the present invention is not limited to a vehicle, and can be applied to, for example, a housing window opening / closing mechanism and other control cables.

(4) Features of Embodiment The control cable (for example, cable ASSY3) mounting structure has a cylindrical long member (for example, the outer casing 33) that covers the inner cable (for example, the lifting cable 31) (for example, the outer casing 33). , The second end portion 52) is a mounting structure for mounting the mounting target (for example, the drum housing 5). Here, the cylindrical elongate member has an engaging portion (for example, an end cap 53) that engages with an attachment target. The attachment target includes an accommodating part (for example, accommodating part 75), an engaged part (for example, engaging claw 81), and a position restricting member (for example, position restricting member 77). The accommodating part (accommodating part 75) can receive the engaging part (end cap 53). The engaged portion (engaging claw 81) is engaged with an engaging portion (end cap 53) accommodated in the accommodating portion (accommodating portion 75) (for example, an engagement stage of the end cap 53). The engagement release position (for example, the position of the engagement claw 81 where the contact surface 83 of the engagement claw 81 can come into contact) and the engagement portion (end cap 53) is released (for example, The engagement claw 81 is displaced radially outwardly against the urging force of the leaf spring member 82, and the engagement claw 81 is disengaged from the abutment relationship with the engagement step portion 54 of the end cap 53). An insertable position where the distal end portion (second end portion 52) of the cylindrical long member (outer casing 33) can be inserted into the accommodating portion (accommodating portion 75) (for example, the distal end portion of the end cap 53 is an engaging claw). The engaging claw 8 that can receive the end cap 53 in the accommodating portion 75 by pressing 81 outward in the radial direction. It is displaceable between a position). The position restricting member (position restricting member 77) is a cylindrical long member that is located outside the accommodating portion (accommodating portion 75) in a state where the engaging portion (end cap 53) is accommodated in the accommodating portion (accommodating portion 75). When the member (outer casing 33) is inclined, the tubular long member (outer casing 33) engages the engaged portion (engaging claw 81). A cylindrical elongated member (displaced radially outwardly against the urging force to the position of the engagement claw 81 where the contact relationship with the engagement step portion 54 of the end cap 53 is disengaged) is prevented. The position of the outer casing 33) is regulated.

According to this structure, when attaching the front-end | tip part (2nd end part 52) of a cylindrical elongate member (outer casing 33) to attachment object (drum housing 5), a cylindrical elongate member (outer casing 33) is attached. Since the tip end portion (second end portion 52) displaces the engaged portion (engaging claw 81) to the position where insertion is possible, attachment becomes easy. Furthermore, after the engaging portion of the cylindrical long member (outer casing 33) is accommodated in the accommodating portion (accommodating portion 75) of the attachment target (drum housing 5), the engaging portion (end cap 53) is engaged. By engaging with the joint (claw member 76), the cylindrical long member (outer casing 33) is difficult to come out of the attachment target (drum housing 5). Furthermore, when the cylindrical long member (outer casing 33) is inclined, the position restricting member (position restricting member 77) regulates the position of the cylindrical long member (outer casing 33), so that the engaged member is engaged. The portion (engagement claw 81) is not displaced to the disengagement position. As a result, it is difficult for the tubular long member (outer casing 33) to come out of the attachment target (drum housing 5).

In particular, as shown in the embodiment, the distance between the drum housing 5 and the cable guide 15 can be maintained by applying it to the railless type window regulator 1 that does not use a guide rail for guiding the carrier plate 2. The package of the window regulator 1 can be maintained.

(5) Other Embodiments Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention. In particular, a plurality of embodiments and modifications described in this specification can be arbitrarily combined as necessary.

The present invention can be widely applied to control cables including a cylindrical long member that covers an inner cable.
