Patent number: 10133159Abstract: Provided is a projection type image display device including an antivibration device 4 suppressing a vibration of a projection lens 2. The antivibration device 4 includes an antivibration base fixed to a display device body 1 and a friction sliding mechanism 8 provided on the antivibration base. The friction sliding mechanism 8 attenuates a vibration of the projection lens 2 by causing a lens-side sliding member 14 moving in synchronization with the projection lens 2 and a base-side sliding member 11 corresponding to a part of the antivibration base to contact each other in a pressed state so that both sliding members 14 and 11 frictionally slide on each other.Type: GrantFiled: July 23, 2015Date of Patent: November 20, 2018Assignee: Maxell, Ltd.Inventors: Hidemi Yamada, Shinro Inui
