Vibration isolation devices for playback equipment, etc.

Abstract

Abstract PURPOSE:To obtain a vibration proof device which is not influenced by a thing placed on it by providing plural holes on a fixed frame, fixing vibration proof rubber larger in size than the hole on the holed part, and connecting the vibration proof rubber and a movable frame by connecting parts that pass through the holes. CONSTITUTION:A movable frame 5 is suspended through connecting parts 4a-4d from vibration proof rubber 3a-3d fixed on the upper face of a fixed frame to face plural holes 2a-2d provided on the fixed frame 1. About 1/4 of total weight W on the movable frame is applied to the vibration proof rubber as load. However, distribution of the weight is not strictly uniform. Accordingly, the size of holes 2a-2d on the fixed frame is made changeable to give optimum stiffness. For instance, the part of the hole 2a is made heavier than other parts by a driving mechanism 10 etc. Accordingly, it is balanced with other parts by making the size of the hole 2a small to make stiffness (kg/mm) large.
