徴とする振動隔絶機構。 a sub-chassis on which a signal reproducing mechanism having a turntable, a pickup section, etc. is placed; a device main body housing the sub-chassis; and a plurality of devices suspended between the sub-chassis and the device main body and fixed to the device main body by screws. The vibration isolating mechanism includes a vibration isolator, the vibration isolator includes a parallel leaf spring, a vibration damping member laminated on the parallel leaf spring, and a vibration damping member laminated on the parallel leaf spring to fix the parallel leaf spring. A substantially U-shaped holder inserted into one end of a leaf spring, a low-friction sheet disposed inside the holder, and a rubber disposed inside the holder via the low-friction sheet. , a fixing member inserted into the other end of the parallel plate spring to fix the parallel plate spring and the device main body, and the sub-chassis is inserted into the holder through the low-friction sheet. The vibration isolators are screwed to the main body of the device via the fixing member so that the vibration isolators are inserted and slid into the apparatus body, and the vibration isolators are combined in different directions and fixed at positions orthogonal to each other. A vibration isolation mechanism characterized in that spring constants in three directions can be independently set arbitrarily.
