Title: Actuator for vibration-proof apparatus
Inventor: OTAKE YASUO
IPC: F16F15/03
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To improve strength of an arm and enable smooth drive without generation of magnetic friction by forming an arm to support a coil of an actuator with a non-magnetic metal material and providing a slit between the external circumference of the arm and a hollow part provided at the center of the arm. SOLUTION: A magnet yoke 1 is fixed to a frame 3 in the drive side via a shim 5 and a moving element 2 is fixed to a frame 4 in the load side. Height adjustment is performed with the shim 5 while the magnet yoke 1 and moving element 2 are not in contact condition. When a current is impressed to the coil, the load side frame 4 is driven relative for the drive side frame 2. Here, the coil material is bonded for the fixing purpose to the aluminum arm. The center part of the arm is formed as a hollow part 80 and a slit 81 is provided between the hollow part 80 and external circumference of the arm. Thereby, strength of the arm can be improved, a larger load can be driven in comparison with that when a resin is used and smooth drive can also be realized without generation of magnetic friction.
