<P>PROBLEM TO BE SOLVED: To provide a vibration isolation device which can isolate continuous and small vibration generated as a mobile body moves, and also can quickly absorb to isolate sudden and large vibration (impact). <P>SOLUTION: The vibration isolation device 1, which is provided and interposed when a camera K is fixed to the mobile body B to isolate vibration generated as the mobile body moves, includes: a support plate 2 for supporting the camera; a mounting plate 3 disposed so as to oppose this support plate and mounted on the mobile body; and a vibration isolation mechanism 10 provided between the support plate and the mounting plate, wherein the vibration isolation mechanism includes a coil spring (elastic member) 11 provided across the support plate and the mounting plate, a viscoelastic sheet resin (viscoelastic member ) 12 provided on the elastic member so as to absorb energizing force in an expansion and contraction direction of this coil spring, and a magnet 13 provided on the mounting plate to impart magnetic force so as to control the vertical movement of the support plate. <P>COPYRIGHT: (C)2013,JPO&INPIT |
