摘要： A bearing unit includes a radial bearing; a thrust bearing; a path forming member; a housing; viscous fluid; and a communicating path. The communicating path has an axial path formed in the axis direction on a circumferential face of the radial bearing and a second end side path formed on the second end side face of the radial bearing. The second end side path is formed by a plurality of projections formed on one of the second end side face of the radial bearing and a face of the housing opposing to the second end side face of the radial bearing. The cross section of the second end side path has a cross sectional area greater than that of the cross section of the axial path.

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.
