A bush assembly includes an inner cylindrical member for supporting an elongated member, a rigid sleeve slidably fixed to the outer surface of the inner cylindrical member via a slipping member, and an outer cylindrical member fixed to the outer surface of the rigid sleeve via an elastic member. The rigid sleeve has a greater diameter portion at one end thereof so that an annular space is formed between the greater diameter portion and one end of the inner cylindrical member. The bush assembly further includes a sealing member which is disposed in the annular space for preventing muddy water or the like from getting into the interfaces between the slipping member and the inner cylindrical member and between the slipping member and the rigid sleeve. The elastic member has a radially extending projection for interrupting muddy water or the like getting into the interface between the outer cylindrical member and a member which is to be connected another member via the bush assembly. |
