Abstract

PURPOSE: To effectively utilize the rigidity of a movable-side bearing against vibrational forces and make the bearing sufficiently movable under a preload or the thermal deformation of a rotary shaft by fixing the bearing by the frictional force generated by the recoil strength of a friction member.
CONSTITUTION: In a bearing device suitable for use in a spindle requiring silent rotation, a rotary shaft 401 is rotatably supported by a static pressure journal bearing 408 fitted to a housing 402. The left end of the shaft 401 is supported in the axial direction by a fixed-side thrust bearing 403, and the right end by a movable-side thrust bearing 404. The thrust bearing 404 is movable axially relative to the housing 402 and biased by a coil spring 406 (biasing member) through friction spacers 405 and 407.
