Abstract:
1. A joint structure between members in which an elastic member is inserted and held in an annular frame provided on a first member and the first member is joined to a second member having a distal end of columnar shape through the elastic member by inserting the distal end of the second member into the elastic member, wherein the distal end of the second member has a distal end face, a large diameter part and a small-diameter part forming a recessed portion at the distal end of the second member, said large diameter part being closer to the distal end than said small diameter part with said small diameter part being spaced a predetermined distance away from the distal end face toward a root of said second member, and a flange closer to the root than the small-diameter part and extending radially outward, the elastic member has a through hole extending in the direction of insertion of the second member and an engagement projection projecting from the inner surface of the through hole, and the joint structure is so constructed that the first and second members are joined together by inserting and holding the elastic member in the annular frame and inserting the distal end of the second member into the through hole of the elastic member to fit the engagement projection into the recessed portion and bring the flange into abutment with an end surface of the elastic member located toward the root of the second member, wherein the large diameter part of the second member is located in the through hole of the elastic member, and an outer surface of the large diameter part is surrounded by the elastic member.
