Abstract

PROBLEM TO BE SOLVED: To inhibit the shortage of an adhesive caused by remaining air in a damper 16 when assembled and to prevent the deterioration, etc., of a feeling in using a grip caused by the remaining air when the adhesive damper 16 is integrally attached by putting a spacer 18 between a leg part 1a of the grip body 1 rotated and energized toward the retracted position and the attaching seat 6. SOLUTION: A recess 13 whose section is circular, extending in the axial direction X of a support shaft 12 is opened in a support part 11 of the attaching seat 6, and a cylindrical engaging shaft 14, extending from the bottom of the recess 13 toward the opening part 13a of the recess, is disposed. An inserting part 19 on the top end side of the cylindrical spacer 18 is inserted into the recess 13, and the engaging shaft 14 is engaged with an engagement part 29 inside the inserting part 19. The recess 13 is closed by a large diameter part 20 of the spacer 18, and the internal space of the recess 13 is filled with the adhesive L. Necessary adhesive resistance is achieved by the adhesive L filling the gap between the inner surface of the recess 13 and the outer surface of the inserting part 19 of the spacer 18 or the gap between the inner surface of the engaging part 29 and the outer surface of the engaging shaft 14. The gap α between the top end surface of the inserting part 19 of the spacer 18 and the bottom of the recess 13 is larger than the gap between the bottom of the engaging part 29 and the top end surface of the engaging shaft 14.
