Title:
DAMPER
Document Type and Number:
WIPO Patent Application WO/2016/009927
Kind Code:
A1
Abstract:
This damper absorbs the axial run-out of a moving member that moves in a reciprocating manner along an axial center while using a load that has hysteresis characteristics to damp the moving member. A push rod (4) that is to be damped by the damper (100) comprises side surfaces (441) to (446) that are inclined with respect to an axial center (O). The damper (100) comprises a bush (2), an elastic body (3), and a cylindrical case (10) for housing the bush (2) and the elastic body (3). The bush (2) comprises a plurality of sliding sections (20) that support the side surfaces (441) to (446) of the push rod (4) by means of a sliding surface (22). The sliding sections (20) elastically deform so as to be displaced in the direction leading away from the axial center (O) of the push rod (4) and in the direction approaching the axial center (O) of the push rod (4). The elastic body (3) is arranged between the inner wall surface (104) of the case (10) and the bush (2) and biases the sliding sections (20) of the bush (2) toward the axial center (O) of the push rod (4) so that the sliding surfaces (22) thereof are pushed against the side surfaces (441) to (446) of the push rod (4).
