The inner ring and the outer ring holds a workpiece therebetween. The screw mounts are disposed at the dividing portion to oppose each other. The lever is disposed at one of the screw mounts and rotatable about a rotation axis. The nut is slidably held in the lever at a position eccentric from the rotation axis. The adjusting screw is mounted across the screw mounts and threadedly engaged with the nut. A shortest distance between a first surface of the one of the screw mounts and the nut is defined as a specific distance.
