  Further, the extension portion 68 faces between the pair of opposed bearing portions 32 formed on the base member 20. The surface of the extension portion 68 is formed on substantially the same plane as the outer periphery of the bearing portion 32. The base member 20 is made of a high-strength material that can hold the mounting component firmly, such as polyacetal reinforced with glass fiber, and the clip 40 has strength but elasticity, such as glass fiber. Since the material is made of polyolefin or the like reinforced with the above, attachment strength that can withstand a large load can be obtained.

  Next, an assembly procedure of the assist grip fixing device 70 will be described with reference to FIGS.

  First, the clip 40 is attached to the base member 20. As shown in FIG. 5A, the base end portion 41 of the clip 40 is obliquely inserted into the base member 20 so that the base end portion 41 of the clip 40 is aligned with the opening 23 of the base member 20. . At this time, both end portions 47 of the elastic piece 44 abut against the rib 25 of the base member 20.

  In this state, when the clip 40 is pushed toward the base member 20 and twisted in the direction of arrow A in FIG. 5A, the base end portion 41 passes through the opening 23, and both end portions 47 of the elastic piece 44 are The rib 25 is fitted to the inner periphery. This state is shown in FIG. 5B and FIG.

  The base end portion 41 inserted on the back surface side of the opening portion 23 is rotated by a torsional force and abuts against a pair of stopper portions 24 formed on the surface 22 of the base member 20, each side of which is a peripheral wall 28. Is almost parallel to the angle. As a result, the four corners of the base end portion 41 are engaged with the peripheral edge of the opening 23, and the clip 40 is fixed to the base member such that the both ends 47 of the elastic piece 44 and the base end portion 41 sandwich the surface 22. 20 is fixed.

  As a result, the rotation position of the base end portion 41 is regulated by the stopper portion 24, and the base end portion 41 can be reliably engaged with the periphery of the opening portion 23. In the present embodiment, the inclination angle θ of the opening 23 with respect to the peripheral wall 28 is set to be smaller than 45 °, and the base end portion 41 is connected to the stopper portion 24 with the twist angle of the clip 40 being relatively small. It can be made to contact.

  Meanwhile, two assist grip fixing devices 70 are used for one assist grip body 10. In this case, the torsion coil spring 90 is attached to one assist grip fixing device 70, and the cylindrical damper 80 is attached to the other assist grip fixing device 70. The torsion coil spring 90 and the cylindrical damper 80 are each attached between the bearing portions 32 formed on the base member 20.

  That is, as shown in FIGS. 7B and 8, the torsion coil spring 90 first has the tip of the end 92 extending in the axial radial direction from the other end of the torsion coil spring 90 to the base member 20. The spring engagement groove 30 is inserted and engaged, and the torsion coil spring 90 is compressed and mounted between the bearing portions 32 formed on the base member 20. Since the free length of the torsion coil spring 90 is longer than the distance between the bearing portions 32, when the torsion coil spring 90 is mounted between the bearing portions 32 in a compressed state and then released, the torsion coil spring 90 self-repels. Both ends are pressed against each other between the opposing surfaces of the bearing portion 32 by force, and movement in the axial direction is restricted. Further, since the end 92 of the torsion coil spring 90 is engaged with the spring engagement groove 30 formed in the base member 20, the movement of the torsion coil spring 90 in the rotational direction is also restricted.

  On the other hand, as shown in FIGS. 7D and 9, the cylindrical damper 80 is first mounted between the bearing portions 32 formed on the base member 20 and the end surface of the inner cylinder. The convex rib 82 formed on the inner surface of the bearing portion 32 is inserted into and engaged with the concave groove 34 formed on the inner surface of the one bearing portion 32. By engaging the convex rib 82 with the concave groove 34, the movement of the cylindrical damper 80 in the rotational direction is restricted. Further, since the length between both end faces of the cylindrical damper 80 is only slightly shorter than the distance between the bearing portions 32, when the cylindrical damper 80 is mounted between the bearing portions 32, the axial direction is reduced. Movement is also restricted.

  Thereafter, as shown in FIGS. 7C and 7E, the base member 20 is attached to the base member 20 to which the torsion coil spring 90 is attached and the base member 20 to which the cylindrical damper 80 is attached. Each of the covers 60 is mounted from the surface 22 side. Then, as shown in FIGS. 8 and 9, the engaging claw 63 (see FIG. 4B) formed on the both side walls 62 of the cover 60 has the locking step portion 35 formed on the base member 20. To prevent it from coming off. Further, the end face of the frame-like protrusion 65 formed on the inner surface of the cover 60 is brought into contact with the base end portion 41 of the clip 40, and the rib 66 protruding from the inside of the frame-like protrusion 65 has a base end. It is inserted into the tool insertion groove 42 formed in the portion 41, and its end surface comes into contact with the bottom surface of the tool insertion groove 42. For this reason, when the clip 40 is pushed into the mounting hole 56 formed in the vehicle body panel 55, the base end portion 41 is moved via the frame-like protrusion 65 and the rib 66 by pushing the concave portion 64 of the cover 60 with a finger. When pressed, the elastic piece 44 formed on the clip 40 can be inserted into the mounting hole 56.

  Further, as shown in FIGS. 7C, 7E, 8 and 9, when the cover 60 is attached to the base member 20, the extension portion extending forward from the front edge 67 of the cover 60. 68 faces the pair of opposed bearing portions 32. Since the surface of the extension portion 68 is formed on substantially the same plane as the outer periphery of the bearing portion 32, the cooperation with the bearing portion 32 provides a smooth appearance in which the bearing portion 32 and the extension portion 68 are continuous with each other. The product value is improved. Further, the torsion coil spring 90 and the cylindrical damper 80 mounted between the pair of opposed bearing portions 32 are temporarily held between the extension portion 68 provided on the cover 60 and the surface 22 of the base member 20. Even if it is transported as it is, it does not fall off and is easy to handle. At this time, an end 91 that extends in the axial radial direction from one end of the torsion coil spring 90 and is bent into an L shape is brought into contact with the tip of the extension 68 formed in the cover 60.

  In the present embodiment, since the torsion coil spring 90 or the cylindrical damper 80 is temporarily held between the bearing portions 32, it can be delivered with these attached, and the parts management can be simplified. .

  Further, as shown in FIG. 9, when the cylindrical damper 80 is temporarily held between the extension 68 provided on the cover 60 and the surface 22 of the base member 20, the cylindrical damper 80 moves in the radial direction. The damper hole 81 formed in the cylindrical damper 80 is disposed substantially coaxially with the bearing hole 33 formed in the bearing portion 32. In the figure, the damper hole 81 and the bearing hole 33 are shown with the same diameter. On the other hand, as shown in FIG. 8, the inner diameter of the torsion coil spring 90 is larger than that of the bearing hole 33.

  The two assist grip fixing devices 70 that temporarily hold the torsion coil spring 90 and the cylindrical damper 80 in this way are attached to the recesses 13 formed at both end portions 11 and 12 of the assist grip body 10.

  As shown in FIG. 10, when attaching each assembled assist grip fixing device 70 to the recess 13 formed in both end portions 11, 12 of the assist grip body 10, first, the bearing portion 32 of the base member 20 is attached to the bearing portion 32. The bored bearing hole 33 is aligned with the shaft hole 14 bored in the recess.

  Further, at that time, an end 91 bent in an L shape of the torsion coil spring 90 temporarily held in the assist grip fixing device 70 attached to the recess 13 of the one end 11 of the assist grip body 10 is provided. It engages and engages with a groove 17 (see FIG. 1) formed in the recess 13. Furthermore, an outer cylinder projection 83 formed on the outer cylinder of the cylindrical damper 80 temporarily held by the assist grip fixing device 70 attached to the recess 13 of the other end 12 of the assist grip body 10 is formed in the recess 13. It is hooked on the formed rib 16 (see FIG. 1).

  Next, the support shaft 15 is inserted into the shaft hole 14 and the bearing hole 33 of the bearing portion 32 that is coaxially aligned with the shaft hole 14, and the bearing hole 33 is inserted through the support shaft 15. The shaft hole 14 is rotatably supported. At this time, the damper hole 81 drilled in the cylindrical damper 80 is temporarily held in a state of being arranged substantially coaxially with the bearing hole 33 drilled in the bearing portion 32, and the torsion coil Since the inner diameter of the spring 90 is larger than that of the bearing hole 33, when the support shaft 15 is inserted between the pair of opposed bearing portions 32, the support shaft 15 is used as the cylindrical damper 80 or the torsion coil. The support shaft 15 can be mounted relatively smoothly without interfering with the spring 90 and hindering insertion.

  As a result, when the assist grip fixing device 70 is attached to the recess 13 formed in the assist grip body 10, it is only necessary to attach the support shaft 15, so that workability is improved and assembly man-hours can be reduced. .

  Thereafter, the assist grip body 10 is fixed to the vehicle body panel 22 via an assist grip fixing device 70 attached to both end portions 11 and 12 thereof. As shown in FIG. 11, mounting holes 56 for mounting a pair of elastic pieces 44 formed on the clip 40 of the assist grip fixing device 70 are formed in the vehicle body panel 55. Although not shown, an interior material is affixed to the surface of the vehicle body panel 55, and a hole that is slightly larger than the attachment hole 56 is formed in a portion corresponding to the attachment hole 56 of the interior material. .

  First, the front ends of the pair of elastic pieces 44 formed on the clip 40 protruding from the lower surfaces of the both assist grip fixing devices 70 are inserted into the mounting holes 56 and temporarily held. Next, the concave portion 64 formed on the upper surface 61 of the cover 60 is pushed with a finger.

  Then, the base end portion 41 of the clip 40 is pressed through the frame-like protrusion 65 and the rib 66 protruding from the inner surface side of the recess 64, and the bottom surface of the base member 20 is stuck to the vehicle body panel 55. The rib 25 protruding from the bottom surface of the base member 20 enters the hole that is in contact with the surface of the interior material and is formed in the interior material.

  Furthermore, when the pair of elastic pieces 44 formed on the clip 40 are pushed into the mounting holes 56 and bent inward, and the engaging claw portions 46 formed on the elastic pieces 44 pass through the mounting holes 56, The engaging claw portion 46 engages with the peripheral edge on the back surface side of the mounting hole 56 by the return of the elastic piece 44. As a result, the plate thickness side of the vehicle body panel 55 is sandwiched between the rib 25 and the engaging claw portion 46 to fix the assist grip fixing device 70, and the assist grip body 10 is connected to the vehicle body panel 55 via the assist grip fixing device 70. Fixed to. At that time, the guide projection 26 protruding from the rib 25 of the base member 20 is inserted into the inner periphery of the mounting hole 56 and inserted into the gap between the clip 40 and the inner periphery of the mounting hole 56. The backlash between 40 and the mounting hole 56 is prevented.

  Then, after the assist grip body 10 is attached to the vehicle body panel 55 and the external force applied to the assist grip body 10 is released, the assist grip body 10 is rotated in the direction closer to the vehicle body panel 55 by the urging force of the torsion coil spring 90. Moved back to the storage position automatically.

  In this manner, after the assist grip body 10 is attached to the vehicle body panel 55 through the pair of assist grip fixing devices 70, the passenger grips the assist grip body 10 and applies the biasing force of the torsion coil spring 90. On the other hand, as shown in FIG. 12, when it is caused to reach the use position, the cover 60 of the assist grip fixing device 70 is exposed. An extension 68 is formed on the front edge 67 of the cover 60, and the extension 68 faces between the bearings 32 formed on the base member 20 to form a cylindrical shape with the torsion coil spring 90. The damper 80 is covered. Therefore, the torsion coil spring 90 and the cylindrical damper 80 are not exposed to the outside, and a good aesthetic appearance can be obtained. In addition, since the surface of the extension portion 68 is formed on substantially the same surface as the outer periphery of the bearing portion 32 disposed on both sides thereof, the entire shape becomes a continuous shape by cooperation with the bearing portion 32, which is more excellent. A beautiful aesthetic can be obtained.

  When the hand is released from the assist grip body 10, the assist grip body 10 is rotated in the retracted position direction by the urging force of the torsion coil spring 90. At this time, relative rotation occurs between the inner cylinder and the outer cylinder of the cylindrical damper 80 held by the assist grip fixing device 70 attached to the end 12 provided at the other end of the assist grip main body 10, and the outer cylinder A braking force is generated by a braking member such as viscous oil filled between the inner cylinder and the inner cylinder.

  Further, since the rib 66 projecting from the inner surface of the cover 60 is inserted into the tool insertion groove 42 of the base end portion 41 of the clip 40, turning force or the like acts on the base member 20 via the assist grip body 10. Even so, the rotational force is transmitted to the clip 40 via the rib 66 of the cover 60 attached to the base member 20, and the rotation of the clip 40 can be restrained by the engaging force with respect to the mounting hole 56. As a result, the base member 20 and the clip 40 are rotated relative to each other during use, and the base end portion 41 of the clip 40 is aligned with the opening 23 to prevent the base member 20 from being detached from the clip 40. can do.

  Further, since the frame-like protrusion 65 is provided on the inner surface of the cover 60 and the tip thereof is brought into contact with the base end portion 41 of the clip 40, when the clip 40 is pushed into the mounting hole 56 of the vehicle body panel 55, A pressing force can be transmitted to the clip 40 via the frame-shaped protrusion 65 by applying a force to the concave portion 64 by applying a finger. Further, in the fixed state, the frame-like protrusion 65 abuts on the base end portion 41 of the clip 40 and prevents its lifting, so that rattling or the like can be prevented. Note that the frame-like protrusion 65 only needs to have a shape that comes into contact with the base end portion 41 and does not necessarily have a frame shape.

  Further, by providing the rib 25 of the base member 20 with the guide protrusion 26 that is inserted into the inner periphery of the mounting hole 56, the gap between the mounting hole 56 and the clip 40 is filled with the guide protrusion 26, and the lateral direction Backlash can be prevented.

  Further, by providing the concave notch 27 at the corner of the guide protrusion 26 that rises from the rib 25 of the base member 20, the rib 25 can be brought into close contact with the interior surface of the vehicle body panel 55, and the assist grip fixing device 70 can be fixed without play.

  Further, an extension 68 is provided on the front edge 67 of the cover 60, and the cylindrical damper 80 and the torsion coil spring 90 are temporarily held between the extension 68 and the base member 20. The product can be delivered as it is, and the parts management can be simplified.

  In addition to the assist grip, the present invention can also be used as a fixing device for fixing parts such as a vehicle sun visor and a room mirror to a mounting surface such as a vehicle body panel.
