Abstract: A bearing portion includes an upper dynamic pressure portion, a lower dynamic pressure portion, and an intra-bearing space defined between a lower surface of a fluid in the upper dynamic pressure portion and an upper surface of a fluid in the lower dynamic pressure portion, and not including the fluid. An airway defined in a shaft includes an inner opening arranged to be in communication with the intra-bearing space, and an outer opening arranged to be in communication with an extra-bearing space. Each of the inner and outer openings is defined in a side surface of the shaft. The extra-bearing space and the intra-bearing space are arranged to be in communication with each other through the airway. The airway is arranged to extend substantially in a straight line or lines, is angled with respect to a central axis, and has no other openings than the inner and outer openings. This contributes to preventing a gas inside of a housing from leaking out of the housing through the airway. In addition, since the airway is arranged to extend substantially in a straight line or lines to join the inner and outer openings to each other, the airway can be defined by a single process using a drill, an EDM, or the like.

Abstract: A wheel-supporting roller-bearing unit with air compressor that is compact and capable of keeping resistance against the rotation of the hub 4c low while at the same time maintaining good balance, and when necessary, is capable of obtaining compressed air having sufficient pressure regardless of the traveling speed of the vehicle. A plurality of cylinder holes 53 are located at a plurality of locations that are evenly spaced around the circumferential direction on the inside of a cylinder block 50 that is connected and fastened to the inside end section in the axial direction of the hub 4c. Pistons 54 fit inside these cylinder holes 53 and are moved back and forth by a piston-drive mechanism 62 as the cylinder block 50 rotates. The air compressor 2c is a reciprocating-piston compressor, so it is possible to obtain the required air pressure regardless of rpm. Also, by placing a plurality of cylinder holes 53 and pistons 54 at uniform intervals around in the circumferential direction, it is possible to suppress the resistance against the rotation of the hub 4c.
