Abstract
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.

A clamping method for clamping a boot band for fixing a boot to be mounted to a constant velocity universal joint by radially shrinking the boot band with use of clamping means comprising a pair of claw members, the clamping method comprising:
- positioning the pair of claw members in a circumferential direction;
- positioning the pair of claw members so that an axial position of the pair of claw members is aligned with an axial position of the boot band;
- and
- clamping the boot band with use of the pair of claw members,
- wherein aligning of the boot band and the constant velocity universal joint in phase with each other in the circumferential direction is carried out by positioning the boot band in the circumferential direction, then confirming completion of the positioning of the boot band in the circumferential direction, then rotating the constant velocity universal joint in the circumferential direction, and then detecting a position of the constant velocity universal joint.
A clamping method for fixing a boot to be mounted to a constant velocity universal joint by looping a belt member configuring a boot band into a ring shape so as to form a ring portion that is fitted to an outside of a band mount portion of the boot, the ring portion comprising a pair of protruding portions spaced apart from each other at a predetermined pitch along a circumferential direction, and bringing the pair of protruding portions close to each other along the circumferential direction with use of clamping means comprising a pair of claw members, so as to radially shrink the ring portion,
- the clamping method comprising:
- positioning the pair of claw members in the circumferential direction;
- positioning the pair of claw members so that an axial position of the pair of claw members is aligned with an axial position of the boot band;
- displacing the pair of claw members in a radial direction of the ring while pivoting, under a state in which the pair of protruding portions of the ring portion is nipped with distal engagement portions of the pair of claw members, the pair of claw members about a pivot portion into a direction in which the pair of claw members are brought close to each other;
- and
- changing positions of the distal engagement portions of the pair of claw members in a manner of following displacements in both the radial direction and the circumferential direction of the pair of protruding portions along with radial shrinkage of the ring portion.
