Abstract
A synthetic resin bearing comprised of synthetic resin-made upper and lower bearing cases and a synthetic resin-made bearing member having a disk-shaped thrust bearing piece and a hollow-cylindrical radial bearing piece with a radially extending slit. The bearing member is disposed such that the radial bearing piece is kept in sliding contact with an outer peripheral surface of a hollow cylindrical portion of the lower bearing case, and the thrust bearing piece is kept in sliding contact with a bottom of an annular recess formed in the lower bearing case. The upper bearing case is assembled to the lower bearing case such that an annular engaging hook portion is snappingly fitted over an annular engaging projecting portion of the lower bearing case. Hermetically sealing portions due to labyrinth action are formed between the upper and lower bearing cases, respectively at the snappingly fitting portion, at an engaging portion between an annular suspended portion of the upper bearing case and an annular groove in the lower bearing case, and at an engaging portion between an annular groove in the upper bearing case and an annular projection of the lower bearing case.
