VIBRATION DAMPING DEVICE

A vibration-proof apparatus which enables the structure of a resin die to be simplified. A vibration-proof apparatus comprising: a coupling member (10) consisting of a resin material and provided with leg part (13) in which thin and thick elastic members (45, 46), which are vulcanized and bonded to short-axis and long-axis attachment bracket members (50, 51), are press-fitted, and also with a main body part (11) which is formed so as to be continuous with the leg parts; a vibration-proof base (40) for connecting an inner cylinder (30) to the main body part (11) of the coupling member (10) and consisting of a rubber-like elastic body. The direction of the axes of press-fitting holes which are formed in the leg parts (13) and into which both the elastic members (45, 46) are press-fitted and the direction of the axis of the inner cylinder (30) are configured to be parallel to each other, and as a result, when the vibration-proof apparatus (1) is removed from the resin die after the coupling member (10) is injection-molded, the vibration-proof apparatus (1) can be drawn in the same direction. Thus, the structure of the resin die can be simplified by simplifying the separation structure of the resin die.
