い高級感が得られる。2. Description of the Related Art Conventionally, as a retractable assist grip of this type, as shown in, for example, Japanese Patent Application Laid-Open No. 9-263166, a pair of protrusions are formed on the legs of the grip body and the vehicle body. The other protrusion is arranged between one protrusion on the grip body side or the vehicle body side, and a coaxial hole is formed between these protrusions, and the hole is composed of an outer cylinder and an inner shaft fitted inside thereof. Insert a damper containing high viscosity viscous agent, fix the outer cylinder of the damper to one protrusion on the grip body side or the vehicle body side, and the inner shaft to the other protrusion so that the grip body is in the operating position. It is known that the rotation speed is slowed by giving a resistance due to the viscosity of the viscous agent of the damper when rotating from the storage position to the storage position. When the rotation speed to the retracted position is lowered in this way, the grip body slowly moves from the use position to the retracted position, so that it immediately moves to the retracted position and the grip body hits the vehicle body strongly and makes a striking sound. The desired high quality is obtained.

を下げるようにしたものも知られている。In addition, as disclosed in Japanese Unexamined Patent Publication (Kokai) No. 5-96982, in a grip in which a leg portion of a grip body is supported by a support through a support shaft, the support shaft is viscoelastic. It is also known that a friction brake made of a resin material is brought into contact with the friction brake to provide sliding resistance when the grip body rotates from a use position to a storage position to reduce the rotation speed.

た。However, in the former conventional example (Japanese Patent Laid-Open No. 9-263166), the high-class feeling and durability can be improved to some extent, but there is a limit to further increase the damper effect. . Further, a damper composed of an outer cylinder and an inner shaft is fitted between the protrusions on the grip body side and the vehicle body side as a shaft, and the number of parts for forming the damper mechanism increases, resulting in high cost. There was also a problem.

難しく、摩耗による耐久性の低下を招く虞れもある。On the other hand, the latter conventional example (Japanese Patent Laid-Open No. 9698/1993)
In Japanese Patent Laid-Open No. 2), since it is necessary to provide a friction brake for contacting the bearing shaft in the support body, the number of parts of the damper mechanism increases. Further, since the rotation of the grip body is suppressed by the sliding resistance, it is difficult to give a high-grade feeling to the movement, and there is a possibility that durability may be deteriorated due to abrasion.

間の空間に粘性剤が介在されている。At least one mounting seat of the pair of mounting seats is provided with a bottomed recess on one side surface of both side surfaces facing each other in the axial direction of the grip body leg. The bottom of the recess is integrally provided with a fitting shaft extending in the recess toward the opening side. In addition, a spacer having a bottomed fitting portion into which the fitting shaft is fitted is rotatably inserted from the tip side into the recess, and the spacer is gripped on the bottom side (base end portion) of the fitting portion. It is non-rotatably attached to the leg of the main body. Further, a viscous agent is interposed in the space between the outer peripheral surface of the spacer and the inner peripheral surface of the recess of the mounting seat.

に高級感が得られる。With the above structure, when the grip body rotates with respect to the mounting seat, the spacers that are non-rotatably mounted on the leg portions of the grip body rotate around the fitting shafts in the recesses of the mounting seat. The space between the inner peripheral surface of the recess of the mounting seat and the outer peripheral surface of the spacer is radially outside as compared to the space between the inner peripheral surface of the fitting portion of the spacer and the outer peripheral surface of the mounting shaft of the mounting seat, Since the viscous agent is present in the space between the inner peripheral surface of the recess of the mounting seat and the outer peripheral surface of the spacer, which is the outer side of the space of these two layers, the space between the mounting seat and the spacer on the grip body side is higher. A damper having a damper effect is formed, and the viscosity of the viscous agent in the damper causes resistance to the rotation of the spacer. As a result, the grip body slowly rotates, and the movement feels high-class. Is obtained.

できる。According to the second aspect of the invention, the viscous agent is interposed in the space between the inner peripheral surface of the fitting portion of the spacer and the outer peripheral surface of the fitting shaft of the mounting seat. Thus, when the grip body rotates with respect to the mounting seat, not only the viscous resistance of the viscous agent in the space between the recess inner peripheral surface of the mounting seat and the outer peripheral surface of the spacer, but also the inner peripheral surface of the fitting portion of the spacer. Rotational resistance is also generated by viscous resistance of the viscous agent in the space between the outer peripheral surface of the insertion shaft and the outer peripheral surface of the fitting shaft, and the damper effect can be further improved by increasing the rotational resistance due to both of them. Further, since the rotation resistance portion made of the viscous agent is arranged in two layers around the rotation axis, the length of the damper in the axis direction can be shortened accordingly.

が得られる。When the grip body 1 is pivoted from the use position to the storage position (the same happens when the grip body 1 is pivoted from the storage position to the use position), the bearing of the right leg 1a of the grip body 1 is rotated. The part 3 rotates around the support shaft 12 of the mounting seat 7, and the spacer 18 fixedly mounted on the right leg 1a of the grip body 1 rotates in the recess 13 of the mounting seat 7, respectively. Since the viscous agent L is interposed in the space between the inner peripheral surface of the concave portion 13 of the mounting seat 7 and the outer peripheral surface of the insertion portion 19 of the spacer 18, the viscosity of the viscous agent L causes the spacer 18 and the grip body 1 to be viscous. Resistance (torque) is generated in the rotation of. Moreover, since the viscous agent L is also present in the space between the inner peripheral surface of the fitting portion 22 of the spacer 18 and the outer peripheral surface of the fitting shaft 14 of the mounting seat 7, the viscous agent L is also rotated by the viscosity of the viscous agent L in this space. Dynamic resistance occurs. As a result, the grip body 1 slowly rotates from the use position to the storage position, and the grip body 1 does not hit the vehicle body B strongly to generate a hit sound, and a high-grade feeling can be obtained from the movement.
