ABSTRACT:
Either an inner ring or an outer ring is formed to protrude in the direction of the rotation axis more than the other of outer ring or inner ring. For example, the bearing12is supported by the bearing housing11aon the outer peripheral face12bof the outer ring, and rotatably supports the hub31aon the inner peripheral face12aof the inner ring. In this bearing12, the inner ring is formed to be longer and protrude further than the outer ring in the direction of the rotation axis, and an engagement/support face12cfor enagageably supporting the drive sprocket92is formed on the outer periphery of the inner ring formed to protrude as described above. The drive sprocket92is able to secure the coaxiality thereof by the engagement with the engagement/support face12c, and receive the transmittance of rotating torque by engaging with the hub-side spline31con the spline92c.
