摘要

PROBLEM TO BE SOLVED: To prevent deformation of a locking member when a housing is subjected to outsert molding.

SOLUTION: The bearing unit is provided with a shaft 31; a radial bearing 33 for carrying out supporting in a circumferential round direction of the shaft 31; a thrust bearing 34 for supporting one end in a thrust direction of the shaft 31; a housing 37 formed by a molded body made of synthetic resin, arranged with the radial bearing 33 and the thrust bearing 34 at the inside and having a structure that a part except for a shaft insertion hole through which the shaft 31 is penetrated is closed; a locking member 46 provided at one end side of the radial bearing provided with the thrust bearing 34 and preventing the shaft 31 from being removed from the radial bearing 33; and a viscous fluid filled in the housing 37. The locking member 46 comprises a material having higher thermal deformation temperature than the temperature applied to the locking member 46 when the housing 37 is molded.
