摘要： A bearing unit is provided which includes a shaft (51) to support rotatably, radial bearing (55) to support the shaft (51) circumferentially, a thrust bearing (66) to support the shaft (51) in the direction of thrusting, and a housing (56) having the radial bearing (55) and thrust bearing (66) disposed therein and in which a viscous fluid (57) is filled. The housing (56) has a sealed structure except for a shaft insertion hole (65) formed therein and through which the shaft 51 is introduced. Between the outer surface of the shaft (51) and the inner surface of the shaft insertion hole (65), there is defined a gap (69) having a sufficient width to prevent the viscous fluid (57) filled in the housing (56) from leaking out of the latter. The housing (56) is formed as a one-piece structure by molding a synthetic resin.

摘要： A bearing unit for rotatably supporting a shaft comprises a seamless holding member with a gap allowing a shaft to run through and extend to the outside, a bearing arranged in the inside of the holding member to rotatably support the shaft so as to make it radially revolvable, an anti-shaft-release member fitted to the shaft so as to abut the bearing in order to prevent the shaft from slipping away in the thrusting direction and a space-forming member arranged in the inside of the holding member so as to secure a space around the anti-shaft-release member. A bearing unit may further comprise an lubricating oil seal member and the space-forming member may be used to form a passage way for lubricating oil to prevent lubricating oil from leaking.

摘要： The bearing unit of the present invention has: a shaft; a radial bearing which supports the shaft in a circumferential direction of the shaft; a thrust bearing which supports an end of the shaft in a thrust direction of the shaft; a housing having a closed structure except for a shaft insertion hole in which the shaft is inserted, with the radial bearing and the thrust bearing being provided inside the housing; a stopper member which prevents the shaft from being pulled out of the radial bearing; and viscous liquid filled in the housing. The stopper member is made of an elastic member which is elastically deformed only in the radial direction and is hardly deformed in the axial direction. Hence, the shaft is prevented from being pulled out from the housing, and shortage of the lubrication oil around bearing surfaces is prevented from being caused by lifting of the shaft.
