Abstract

PURPOSE: To prevent falling off of outside wall of the crank case etc. of a motor cycle owing to deterioration of the elastic member by pressure-fitting and engaging the elastic member to the case compulsorily by means of springs arranged inside said elastic member.
CONSTITUTION: A ring-shaped receptacle 13, rising vertically from the periphery of easily resonating wall 11 of crank case 10 forms a concave 15 with its internal circumferential surface 14, and a ring-shaped rubber member 16 is fitted is this concave 15. The outside wall 12 is fitted in the opening provided inside said rubber member 16, and when it is fitted in the internal circumferential surface 14 of the receptacle 13 an L-shaped groove 23 is formed from the end face in contact with the innermost wall 11 to the central part. At the end of this groove 23, a ring- shaped spring 24 expanding outward in the radial direction is fitted, whereby the rubber member 16 is pressed against the internal circumferential surface 14 of the receptacle 13.
