摘要：A bearing unit is provided which includes a shaft () to support rotatably, radialbearing () to support the shaft () circumferentially, a thrust bearing () to support the shaft() in the direction of thrusting, and a housing () having the radial bearing () and thrust
bearing () disposed therein and in which a viscous fluid () is filled. The housing () has asealed structure except for a shaft insertion hole () formed therein and through which theshaft is introduced. Between the outer surface of the shaft () and the inner surface of theshaft insertion hole (), there is defined a gap () having a sufficient width to prevent theviscous fluid () filled in the housing () from leaking out of the latter. The housing () isformed as a one-piece structure by molding a synthetic resin.
