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： A bearing unit and a rotating apparatus which prevent leakage of lubricating oil to the utmost and which are superior in reliability are disclosed. A radial bearing and a thrust bearing support a shaft for rotation, and a path forming member and a path forming member lid form a communicating path having a function of short-circuiting pressure generated when the shaft and the radial bearing rotate relative to each other. A housing has a function of covering and holding the members mentioned while the housing is open at one end of the shaft with a small void left therebetween. Lubricating oil is filled in the void. The path forming member and the path forming member lid fully cover the members mentioned, except a shaft opening side portion of the radial bearing. The housing is made of a molded resin material.
