Abstract

PURPOSE: To seal viscous fluid in a center hole so that smooth sliding can take place between the inner surface of the center hole and the outer periphery of a movable rod slider.
CONSTITUTION: A magnetic circuit is composed of permanent magnets 1A, 1B, a front yoke 2, a back yoke 3, a center pole 4A. Also, a voice coil 8 and a movable rod 5 are concentric at one end and are vertically fixed to a mount surface 9B of a carriage 9A. Between the front yoke 2 and the center pole 4A is formed a gap G. While the electrification of the voice coil 8 moves a rod 5 and a slider 6 in D2 direction, the viscous fluid 8 sealed in the center pole moves in the opposite direction of the arrow D1 to generate damping force against the rod-slider 6.
