Bush, group of bush, suspension cross-member, vehicle, method for mounting a bush and method for mounting a group of bushes

A bush (2a) comprises: an outer member (21a) including an outer main body and an outer flange (212a); an inner member (22a) including an inner main body inserted into the outer member (21a), a inner flange, and a through hole (224a); and an elastic member (23a) disposed between the outer member (21a) and the inner member (22a). The bush (2a) and a bush (2c) are press-fitted into a top aperture and a bottom aperture of a bush-attaching hole (11) in a cross-member, respectively. When the bushes (2a, 2c) are press-fitted, there exists a predetermined clearance between the inner member (22a, 22c). For fixing the cross-member to the body (3), a stud (42) is inserted through the respective through holes (224a, 224c), and a nut (41) is fitted onto the stud (42) and screwed until the inner members abut on each other.
