ABSTRACT:
A hub unit having an outer ring member; an inner ring member a flange part, a large diameter part, and a small diameter part which has an outer circumference channel extending circumferentially in an end of the small diameter part and multiple notches which open the outer circumference channel to the end surface of the small diameter part; a sleeve which fits over the small diameter part of the inner ring member, one end of which contacts a shoulder between the large diameter part and the small diameter part and the other end of which overhangs the outer circumference channel; multiple rolling elements positioned at regular intervals between the outer ring member and the large diameter part of the inner ring member and between the outer ring member and the sleeve; and a ring-shaped bayonet member having multiple engaging parts which respectively project radially inward at positions corresponding to the positions of the notches. The engaging parts are inserted through the notches and fit within the outer circumference channel such that when these engaging parts are fit in the outer circumference channel, the bayonet member presses the end of the sleeve toward the shoulder, the bayonet member being thus pressed against the wall defining the outer circumference channel and locked.
