A boot band for fixing a boot that is mounted to a constant velocity universal joint is clamped. The boot band and the constant velocity universal joint are aligned in phase with each other in a circumferential direction. An axial position of a clamping portion is thereafter aligned with an axial position of the boot band. Then, the boot band is clamped by the clamping portion.

Clamping device

Provided is an inspection device, including: pressurizing means for pressurizing an outer member of a rolling bearing toward an inner member of the rolling bearing, the rolling bearing including the outer member and the inner member rotatable relative to each other through intermediation of balls; rotary drive means for rotating the inner member about an axial center of the inner member under a state in which the outer member is pressurized toward the inner member; detecting means for detecting vibration generated along with the rotation of the inner member so that whether or not the rolling bearing is an accepted product is determined based on values obtained through the detection; and vibration control means to be interposed between the outer member and the pressurizing means, the vibration control means including a holding portion configured to hold the detecting means in a fixed manner.

Inspection device

A method for manufacturing a wheel bearing apparatus by measuring a distance Ho, Hi and Hh. A difference &#x394;H=(Hi+Hh&#x2212;Ho) is compared with a reference value of a model article. Rolling elements are selected with each having an optimum diameter to correct the difference &#x394;H between the measured values and the reference values.
