ABSTRACT:
Herein disclosed is a shock absorber which is to be used with a vehicular coupler. The shock absorber includes a shock absorbing frame which has a pair of shoulders. Further inclusive are a pair of follower plates which are adapted to be held to abut against the shoulders of the shock absorbing frame. A main elastic member is clamped under compression between the paired follower plates. A pair of auxiliary elastic members are also clamped under compression, respectively, between the shock absorbing frame and those faces of the follower plates, which are opposite to the faces contacting with the main elastic member. The initial pressure applied to the main elastic member is balanced by the initial pressures to the auxiliary elastic members. Thus, the paired follower plates can take their neutral positions without being forced onto the shoulders of the shock absorbing frame.
