Description

  The present invention relates to a stopper mainly used for fixing an elevating cord for elevating and lowering an elevating type interior material such as a paddle, a Venetian blind, and a roman shade curtain to a predetermined position.

  Elevating type interior materials (hereinafter simply referred to as “interior materials”) such as paddles, Venetian blinds, and roman shade curtains are suspended by hanging around guides such as pulleys and shafts attached to a fixed frame. It is connected to one end of the cord, and the other end of the lifting / lowering cord is pulled and lifted / lowered. A stopper for lifting and fixing the interior material 58 to a required height is attached to the fixed frame.

In a liftable double-hanging interior material in which two interior materials are double-suspended on one fixed frame, two stoppers for lifting and lowering the two interior materials are attached to both ends of the fixed frame. (For example, see Patent Document 1). As shown in FIG. 9, as the stopper, (a) two V grooves 11, 21 of a first V groove and a second V groove branched in a V shape into left grooves 12, 22 and right grooves 13, 23, The turning points 14 and 24 where the left grooves 12 and 22 and the right grooves 13 and 23 intersect and the continuous points continuing from the turning points 14 and 24 of the left grooves and the right grooves are directed in the same direction 30 on a straight line. (B) the turning point 24 of the second V-groove is located at a portion sandwiched between the branched left groove 12 and right groove 13 of the first V-groove 11, and (c) The left groove 12 of the 1V groove and the left groove 22 of the second V groove are connected by a left curved groove 31 that changes the continuous direction, and the right groove 13 of the first V groove and the right groove 23 of the second V groove change the right direction groove. 32, and (A) those first V groove 11, left curved groove 31, second V groove 21, and right curved groove 32. And a cam plate 41 in which a circulating cam groove 20 continuously forming a heart shape is formed on a flat surface, and (B) on the distal end side of the turning point 14 of the first V groove 11 opposite to the second V groove 21, The cam plate is supported at a predetermined distance from the cam forming surface 42 of the cam plate in which the circulation cam groove 20 is formed, and extends in the width direction 60 perpendicular to the front-rear direction 30 in which the first V-groove 11 and the second V-groove 21 move back and forth. A regulating member 43 that is supported, and (C) a connecting piece 68 that is supported by the cam forming surface 42 so as to be movable in the front-rear direction 30 and that freely fits into the circulation cam groove 20 protrudes from the bottom surface facing the cam forming surface of the cam plate. One having a slider 45 is known (for example, see Patent Document 2). As a stopper composed of this kind of cam plate 41, regulating member 43 and slider 45, a linear groove 44 is provided on the bottom surface of the slider which continues in a straight line in the width direction, and a sphere in place of the connecting piece 68 is a linear groove 44 and a circulation cam groove.

JP 2003-169746 A Japanese Utility Model Publication No. 63-041516 JP 2002-191494 A Japanese Patent Laid-Open No. 2003-024208

  In this type of stopper, the lifting / lowering cord 47 connected to the interior material is pulled between the cam plate 41 and the regulating member 43, pulled out in contact with the surface of the slider 45, and pulled out and suspended from the fixed frame 57. Is pulled down slightly and then released, the slider 45 moves to the regulating material side (43) by being rubbed by the lifting cord 47 pulled back by the action of the gravity of the interior material. At that time, when the connecting piece 68 protruding from the bottom surface of the slider 45 is caught in the first turning point 15 between the left groove 12 and the right groove 13 of the first V groove 11 on the regulating material side (47), the lifting / lowering cord 47 is The slider 45 and the regulating member 47 are sandwiched, and the descent of the interior material stops. On the other hand, when the connecting piece 68 is caught at the second turning point 25 between the left groove 22 and the right groove 23 of the second V groove 21 far away from the regulating member 47, the lifting / lowering cord 47 has the slider 45 and the regulating member 47. The interior material continues to move due to the action of the gravity of the interior material, and therefore the interior material also continues to descend until the tip of the lifting / lowering cord 47 is caught by the fixed frame.

When the connecting piece 68 is caught by the first turning point 15 and the descent of the interior material 58 is stopped, if the tip of the lifting / lowering cord is pulled down slightly and then released, the connecting piece 68 is removed from the first turning point 15. It moves and is caught at the second turning point 25, the lifting / lowering cord 47 becomes free, and the interior material continues to descend until the tip of the lifting / lowering cord 47 is caught by the fixed frame 57. On the other hand, when the connecting piece 68 is hooked on the second turning point 25 and the interior material continues to descend, if the tip of the lifting / lowering cord is pulled down slightly and then released, the connecting piece 68 moves from the second turning point 25. It moves and is caught at the first turning point 15, and the lifting / lowering cord 47 is sandwiched between the slider 45 and the regulating member 47, and the descent of the interior material stops.
In this way, the release operation in which the tip of the lifting / lowering cord is pulled down slightly and then released is switched between the descent state and the stopped state of the interior material. In the release operation, the connecting piece 68 is connected to the first return point 15 and the second return point. It will not continue to engage either point 25.

  The movement of the connecting piece 68 in this releasing operation will be described in more detail with reference to FIG. 9. The right groove 13 of the first V groove 15 has the first turning point 15 at the turning point 14 of the first V groove 11. It is biased to the right side, that is, opposite to the left groove 12 with respect to the center line 40 parallel to the moving direction 30 of the street lifting / lowering cord 47. For this reason, when the connecting piece 68 is caught by the first turning point 15 and the descent of the interior material 58 is stopped, the lifting / lowering cord is operated to release the connecting piece 68 from the first V groove side (11) to the second V When moving to the groove side (21), the connecting piece 68 moves straight along the center line 40 without entering the biased right groove 13, enters the left groove 12 of the first V-groove 15, and remains as it is. When moving to the left curved groove 31 along the left groove 12 and the lifting / lowering cord is released and returned, the groove width of the left groove 22 of the second V groove in the left curved groove 31 is larger than that of the left groove 12 of the first V groove. Is wide and difficult to enter the left groove 12 of the narrow first V-groove, so that the connecting piece 68 enters the left groove 22 of the second V-groove having a wide groove width and is caught by the second turning point 25.

  On the other hand, the left groove 22 of the second V-groove 21 is opposite to the case of the first V-groove 11, and at the turning point 24, the center groove 40 passes through the second turning point 25 and is parallel to the moving direction 30 of the lifting / lowering cord 47. On the other hand, it is biased to the left side, that is, opposite to the right groove 23. For this reason, when the connecting piece 68 is hooked on the second turning point 25 and the interior material continues to descend, when the lifting cord is released, the connecting piece 68 does not enter the biased left groove 22. It moves straight along the center line 40, enters the right groove 23 of the second V-groove 25, moves as it is along the right groove 23 to the right curved groove 32, and when the lifting cord is released and returns, In the groove 32, contrary to the case of the left curved groove 31, the groove width of the right groove 13 of the first V groove is wider than that of the right groove 23 of the second V groove. Instead of entering the right groove 23, it enters into the right groove 13 of the wide first V groove, moves along the right groove 13 to the first V groove 11, and is caught by the first turning point 15.

  Thus, by releasing the lifting / lowering cord, the connecting piece 68 becomes the circulation cam groove in the order of the left groove 12 of the first V groove, the left groove 22 of the second V groove, the right groove 23 of the second V groove, and the right groove 13 of the first V groove. 20 is circulated and moved in one direction, and reciprocated between the first turning point 15 and the second turning point 25. In the moving process, the turning point 14 of the first V groove, the left bent groove 31, and the turning of the second V groove The moving direction of the connecting piece 68 is not reversed at any point of the point 24 and the right curved groove 32. FIG. 10 exemplifies a stopper in which the connecting piece 68 circulates clockwise in the circulation cam groove 20. If the paper surface of FIG. 10 is turned upside down, the circulation movement direction becomes counterclockwise. As described above, the circulating movement direction of the connecting piece 68 can be set to either clockwise or counterclockwise.

  In the stopper in which the connecting piece 68 protrudes from the bottom surface of the slider 45, the slider 45 is guided to the circulation cam groove 20 through the connecting piece 68, and between the left groove (12, 22) and the right groove (13, 23). The lateral width of the stopper is also increased by the amount that the stopper is reciprocated to the left and right than the lateral width of the cam plate 41, so that the fixed frame 57 on which the stopper is mounted should be compact. I can't. In this respect, a linear groove 44 extending in the width direction is provided on the bottom surface of the slider, and a sphere 46 is used instead of the connecting piece 68. The sphere 46 is loosely fitted to the linear groove 44 and the circulation cam groove 20, and the sphere 46 is It seemed more practical to use a stopper in which the cam plate 41 and the slider 45 are connected (linked). However, in the stopper in which the sphere 46 is applied instead of the connecting piece 68, in the practical test, the sphere 46 is not necessarily the left groove 12 of the first V groove, the left groove 22 of the second V groove, the right groove 23 of the second V groove, It does not circulate and move in one direction in the order of the right groove 13 of the 1V groove, the direction of movement sometimes reverses, and troubles due to malfunctions are likely to occur.

  To investigate the cause, first of all, when the mounting method of the fixed frame 58 and the mounting method of the stopper are poor, and the cam plate 41 is not horizontal but slightly inclined, the sphere in the inclined direction. 46 is easy to roll, and the direction of movement is easily reversed at any of the turn point 14 of the first V groove, the left turn groove 31, the turn point 24 of the second V groove, and the right turn groove 32; When the sphere 46 does not move vigorously from the first V groove 11 to the second V groove 21 in the left curved groove 31 or from the second V groove 21 to the first V groove 11 in the right curved groove 32, that is, ascending / descending cord When pulling 47, when it is gentle and the sphere 46 is shockedly pushed out from the first folding point 15 or the second folding point 25 and does not reach the left curved groove 31 or the right curved groove 32, the left curved groove 31. And the sphere 46 is temporarily suspended in the right curved groove 32. When the ball 46 starts to roll in the reverse direction in the temporary stop state, and similarly, when the lifting cord 47 is pulled slowly, the ball 46 goes straight in the moving direction 30 of the lifting cord 47 and the slider 45. Without turning to it, the knowledge that it became easy to roll in the right groove 13 or the left groove 23 in the turning points 14 and 24 was obtained.

  The present invention has been completed by obtaining such knowledge. The purpose of the present invention is to first make the stopper compact so that it does not get out of the way as seen in Patent Document 1.

  In the present invention (Claim 1), the two stoppers 48a and 48b are set so that the longitudinal direction 30 in which the slider moves is aligned with the length direction of the fixed frame 57, and the elevating cords 47a and 47b are connected to the cam plate 41 and the regulating member 43. Since the upper and lower layers are mounted so as to be pulled in through and in contact with the slider 45, the direction of the lifted cords 47a and 47b to be pulled out is also parallel to the length direction of the fixed frame 57 (FIG. 1). . For this reason, a plurality of sets of stoppers 48a and 48b, which are vertically doubled, are attached to the internal gap 65 that continues in the length direction of the fixed frame 57, and the lifting cords are connected to the sets of stoppers 48a and 48b so as to be connected in a straight line. The lifting cords 47a and 47b can be firmly and securely locked by the plurality of sets of stoppers 48a and 48b through the 47a and 47b, and are suspended from the fixed frame 57 by the plurality of sets of stoppers 48a and 48b. The plurality of lifting / lowering cords (47a / 47b, 47a / 47b, 47a / 47b) are individually passed, and the plurality of lifting / lowering cords (47a / 47b, 47a / 47b, 47a / 47b) are individually locked. It is also possible to ensure the raising and lowering operation of the interior materials 58a and 58b. Since the stoppers 48a and 48b are accommodated in the internal space 65 of the fixed frame, the stoppers 48a and 48b do not get in the way, and the stoppers 48a and 48b do not impair the aesthetics of the liftable double-suspended interior material (FIG. 2).

According to the present invention (Claim 2), the roll 50 is rotated by the moving lifting / lowering cord 47, and the rotating roll 50 drives the slider 45 on the cam plate 41 in the moving direction of the lifting / lowering cord 47. For this reason, it is not necessary to bring the lifting / lowering cord 47 into direct contact with the slider 45 in order to move the slider 45, and wear of the lifting / lowering cord 47 due to friction with the slider 45 is avoided. When the slider 45 moves and approaches the restriction member 43 (FIG. 3A), the roll 50 is pressed so that the lifting / lowering cord 47 bites into the irregularities 64 of the restriction member 43 (FIG. 4). Since the cord 47 is locked to the regulating material 43 and the concave and convex groove 63 of the roll 50 is in close contact with the raising and lowering cord 47, the raising and lowering cord 47 is strongly held between the regulating material 43 and the roll 50, The stopper 48 is configured in a compact manner (FIG. 1).
The roll 50 touches the lifting / lowering cord 47 and rotates, and the concave / convex groove 63 meshes with the concave / convex groove 33 of the cam plate, and these constitute a rack gear mechanism. Therefore, the slider 45 is moved by the lifting / lowering cord 47 via the roll 50. It will be driven reliably (FIG. 5). When the sphere 46 moves together with the slider 45 in the direction away from the regulating member 43 and reaches the curved grooves 31 and 32, the force of the regulating member 43 acting to press the lifting / lowering cord 47 against the roll 50 is applied. The lifting / lowering cord 47 becomes free.

  According to the present invention (Claim 3), even if the cam plate 41 (strictly speaking, the groove bottom surface 19) is slightly inclined, the sphere 46 beyond the obstacle (51, 52, 53, 54) As shown in FIGS. 5 and 6, the right groove 13 of the first V groove 15 is not the first V groove as shown in FIGS. 5 and 6. 11 turning points 14 are biased to the right with respect to the center line 40 passing through the first turning points 15 and parallel to the moving direction 30 of the lifting / lowering cord 47, and the left groove 22 of the second V groove 21 is the second V groove 21. At the turning point 24, the clockwise stopper 48 that is biased to the left with respect to the center line 40 that passes through the second turning point 25 and is parallel to the moving direction 30 of the lifting / lowering cord 47, 46 is the left groove 12 of the first V groove, the left groove 22 of the second V groove, The circulation cam groove 20 is circulated in one direction in the order of the right groove 23 of the 2V groove and the right groove 13 of the first V groove, and in the moving process, the turning point 14 of the first V groove, the left curved groove 31, and the second V groove The moving direction is not reversed at any of the turning point 24 and the right curved groove 32, and the malfunction of the stopper 48 is avoided. Similarly, the left groove of the first V groove 15 is biased to the left side with respect to the center line 40 at the turning point 14 of the first V groove 11, and the right groove of the second V groove 21 is turned around the turning point 24 of the second V groove 21. , The sphere 46 is in the order of the right groove of the first V groove, the right groove of the second V groove, the left groove of the second V groove, and the left groove of the first V groove. The circulation cam groove 20 circulates in one direction on one side, and the moving direction does not reverse at any of the turn point 14 of the first V groove, the turn point 24 of the right V groove, the turn point 24 of the second V groove, and the left turn groove. 48 malfunctions are avoided. In this way, even if the cam plate 41 is slightly inclined, there is no malfunction, so there is no need to support the fixed frame 57 and the stopper 48 so that the fixing frame 57 and the stopper 48 are aligned horizontally, and the installation work can be performed easily and efficiently even by an amateur. I can do it. Since such a malfunction does not occur, even if the circulation cam groove 20 and the sphere 46 are made fine to make the stopper 48 compact, the circulation cam groove 20 and the sphere 46 are not required to have high accuracy, and the conventional curtain rail is not required. The stopper 48 can be made compact to such an extent that it can be mounted in the cavity, and the conventional curtain rail can be freely transferred to the fixed frame 58.

  Thus, according to the present invention (Claims 1, 2, and 3), the spherical body 46 is not malfunctioned, the stopper 48 is made compact, and the stopper 48 is vertically and vertically doubled (two in the interior space 65). And it does not get in the way and does not require any special skill to align the fixed frame 57 and the stopper 48 (circulation cam groove 20) horizontally in the mounting work on the ceiling or wall surface. Even an amateur can attach it efficiently and easily, and the elevating cord 47 is securely locked to the stopper 48 so that the elevating height of the interior material 58 can be set to a predetermined height with certainty. A double-hanging interior material that is clean and easy to handle is obtained.

  In the elevating type double hanging interior material, even if a plurality of sets of stoppers 48a and 48b which are doubled up and down are mounted, if one set of the stoppers 48a and 48b is provided at one end of the fixed frame 57, the fixed frame It is convenient that the lift cords 47a and 47b of the two interior materials 58a and 58b can be selectively released at one end of the 57, and the two interior materials 58a and 58b can be selectively lifted and closed ( 1 and 2). In FIG. 2, reference numerals 59a and 59b denote weight bars of a roman shade curtain or a Venetian blind in which gravity acts in a direction in which the elevating cords 47a and 47b are pulled down. In the paddle, the shaft rods 59a and 59b shown in FIG. 2 serve as top bars that lock the upper edges thereof.

5 and 6 illustrate a stopper in which the sphere 46 circulates clockwise.
Between the left groove 12 of the first V groove and the left groove 22 of the second V groove in the left curved groove 31 of the circulation cam groove 20, between the left groove 22 and the turning point 24 of the second V groove, and the second V groove in the right curved groove 32. Between the right groove 23 of the first V groove and the right groove 13 of the first V groove and between the right groove 13 and the turning point 14 of the first V groove are obstacles 51, 52, and 53 that prevent the sphere 46 from returning backward. As 54, a step is provided in which the former between them is higher than the latter.
In the stopper in which the sphere 46 circulates counterclockwise, the second V is formed between the right groove 13 of the first V groove and the right groove 23 of the second V groove in the right curved groove 32 of the circulation cam groove 20 shown in FIGS. Between the right groove 23 and the turning point 24 of the groove, between the left groove 22 of the second V groove and the left groove 12 of the first V groove in the left curved groove 31, and between the left groove 12 and the turning point 14 of the first V groove. As the obstacles 51, 52, 53, and 54 that prevent the spherical body 46 from returning backward, a step in which the former between them is higher than the latter is provided on the groove bottom surface 19 between them.

  FIG. 3 is a cross-sectional side view of the stopper shown in FIG. 6. FIG. 3A shows a slider 45 in a state where the roll 50 and the sphere 46 are closest to the regulating member 43 by a solid line. 43 shows the slider in the state where the roll 50 and the sphere 46 are farthest from 43 by a two-dot chain line, and the partial diagram (b) shows a state in which the sphere 46 is stopped at the second turning point 25 of the second V groove. The slider 45 is illustrated. 3 and 6, reference numeral 55 denotes a cover that covers the cam plate 41 and the slider 45, and the regulating member 43 is attached to the cover 55.

  The regulating member 43 only needs to hold the lifting / lowering cord 47 to the slider 45 so as not to be separated from the slider 45, and may be a part of the cover 55, and the lower side which is doubled up and down The regulating member 43b of the stopper 48b may constitute a part of the back surface of the cam plate of the upper stopper 48a (FIG. 1). The cross-sectional shape of the regulating member 43 may be any shape such as a circle (FIG. 3), a triangle (FIG. 4 (a)), a T-shape (FIG. 4 (b)), an I-shape, or a U-shape. The unevenness 64 of the restricting material 43 may be one in which a plurality of ridges and grooves that continue straight in the length direction of the restricting material 43 are alternated like the uneven groove 63 on the peripheral surface of the roll 50 (FIG. 4A). In addition, a plurality of protrusions may be arranged in the length direction of the regulating member 43 such as a saw tooth (FIG. 4B), or fine protrusions such as sandpaper particles are densely formed. It may be done. Accordingly, the irregularities 64 can be configured by pasting sandpaper on the surface of the regulating member 43.

  The cam forming surface 42 on the tip side of the first V groove 11 opposite to the second V groove of the cam plate 41 is provided with a bulge 49 bulging in a direction facing the regulating member 43, and the bulging 49 has a regulation surface on the surface of the bulging 49. It is preferable to provide an uneven groove that continues parallel to the width direction 60 in which the material 43 extends (FIGS. 3 and 6). When the ridge 49 is provided in such a manner, the slider and the regulating member are sandwiched, and when the slider 45 moves toward the regulating member 43, the ridge 49 is like a wedge driven between the cam plate 41 and the slider 45. In addition, the concave / convex groove 63 on the circumferential surface of the roll meshes with the concave / convex groove on the raised surface (49) to stop the rotation of the roll 50, and the concave / convex groove 63 on the circumferential surface of the roll bites into the lifting / lowering cord 47. The lifting / lowering cord 47 is strongly clamped between the materials 43 (FIG. 3A).

  When the roll 50 touches the moving lifting / lowering cord 47 and rotates, the roll 50 and the cam plate 41 come into strong contact with each other, and the slider 45 is driven in the moving direction of the lifting / lowering cord 47 by the frictional drag generated therebetween. In order to secure a driving force that acts on the slider 45 from the cam plate 41 via the roll 50, an uneven groove 33 that meshes with the uneven groove 63 on the circumferential surface of the roll is attached to the cam forming surface 42 of the cam plate, A rack gear mechanism is formed between the cam plates 41. The concave / convex groove 33 attached to the cam plate is continuously formed up to a position where the spherical body 46 moves together with the slider 45 in the direction away from the first V groove 11 and reaches the left curved groove 31 or the right curved groove 32 (FIG. 5). When the sphere 46 reaches the left curved groove 31 or the right curved groove 32, the roll 50 is released from the concave / convex groove 33 of the cam plate and becomes free, and the roll 50 may be idled by the moving lifting / lowering cord 47. By doing so, it is preferable to avoid wear of the lifting / lowering cord 47 due to the concave and convex grooves 63 on the peripheral surface of the roll. Further, in order to avoid wear caused by touching the slider 45 or the roll 50 of the lifting / lowering cord 47, the lifting / lowering cord 47 is moved from the slider 45 or the roll 50 when the sphere 46 reaches the left curved groove 31 or the right curved groove 32. A guide 56 (FIG. 3B) that pushes up the lifting / lowering cord 47 so as to be separated may be provided at one end of the stopper 48 from which the lifting / lowering cord 47 is pulled out.

The lifting / lowering cord 47 passing through the stopper 48 reliably contacts the slider 45 (roll 50) on the first V-groove side (11), and does not come into strong contact with the second V-groove side (21) away from the slider 45 (roll 50). In order to do so, a guide 66 for guiding the lifting / lowering cord 47 may be disposed before and after the stopper 48 through which the lifting / lowering cord 47 passes (FIG. 1).
The guides 56 and 66 may be rotatable rolls (guide rolls), or they may be attached to the fixed frame 57.

The stopper 48 of the present invention can also be used for a normal elevating type interior material, and in that case, it can also be used in a vertical shape with the moving direction 30 of the slider 45 directed vertically (FIG. 7).
Thus, when the stopper 48 of the present invention is used in the vertical type, (1) a spring is slidably interposed between the slider 45 and the cover 55 via a ball or a roll, and the slider 45 is moved by the spring. (2) The slider 45 is slidably fitted in a dovetail groove provided in the cam plate 41 in parallel with the moving direction 30 of the slider 45, and (3) the moving direction of the slider 45 The lifting / lowering cord 47 is pressure-bonded to the slider 45 by guides 66 and 66 provided before and after (up / down) 30 and the slider 45 is elastically pressed to the cam plate 41 via the lifting / lowering cord 47 (FIG. 7), (4) ) The slider 45 is attracted to the cam plate 41 by the magnet 57 attached to the cam plate 41 (FIG. 7) to prevent the slider 45 and the cam plate 41 from being separated.

The two stoppers 48a and 48b applied to the two elevating cords 47a and 47b for individually elevating and lowering the two interior materials are overlapped and integrated in the upper and lower directions as shown in FIGS. The height of the internal gap 65 of the fixed frame 57 is not more than twice the thickness of the stopper 48, and the two stoppers 48a and 48b can be inserted into the internal gap 65 in a vertically doubled manner. If this is not possible, the two stoppers 48a and 48b can be mounted at different positions in the length direction of the fixed frame 57, that is, at different positions.
In other words, the two stoppers 48a and 48b referred to in the present invention are "upper and lower two layers". The inner space 65 of the fixed frame 57 has a stopper 48a that acts on an elevating cord 47a that moves up and down one interior material 58a; This means that the two stoppers 48a and 48b are attached to the fixed frame 57 so that the two interior layers 58b can be divided into two upper and lower layers by the stopper 48b acting on the lifting / lowering cord 47b that lifts and lowers one interior material 58b.

  In order to prevent the slider 45 from jumping out from the stopper 48 and to increase the locking force acting on the lifting / lowering cord 47 from the restricting member 43 and the roll 50, the distance h between the cam plate 41 and the restricting member 43, that is, the stopper 48. The height h of the frontage is made lower than the thickness t of the entire slider (45) including the roll 50. Therefore, in the stopper 48 which is covered with the cover 55 and the inner surface of the cover 55 and the cam forming surface 42 of the cam plate 41 are parallel, the regulating member 43 protrudes from the inner surface of the cover 55 (FIG. 7), or A protuberance 49 is provided on the cam forming surface 42 of the cam plate 41 (FIGS. 3 and 6), or a regulating member 43 is provided between the cover 55 and the cam plate 41 (FIG. 3).
