The size adjustment piece 6 can be changed to an adjustment mode in which the size adjustment piece 6 is held in a state of protruding from the inner peripheral surface of the ring.
[0025]
In the embodiment of FIG. 6, the shaft 8-3 is attached and fixed so as to pass between the side walls of the groove 7 on the inner peripheral surface of the ring. Then, a non-adjustment mode in which the shaft 8-3 is slidably fitted into a guide groove (through hole) 9-3 provided through the size adjustment piece 6 and the size adjustment piece 6 is held along the inner peripheral surface of the ring. And an adjustment mode in which the size adjustment piece 6 is held in a state of protruding from the inner peripheral surface of the ring.
[0026]
In this example, the shaft 8-3 has a cylindrical main body 101, pins 102 and 103 held so as to be able to advance and retreat in the cylindrical main body 101 on both sides thereof, and a spring 104 that normally biases the pins 102 and 103 in a protruding direction. It consists of and. Therefore, the shaft 8-3 can be easily passed between the side walls of the concave groove 7 on the inner circumferential surface of the ring while pushing the pins 102 and 103 into the cylindrical main body 101.
[0027]
FIG. 7 shows a mode change operation in each of the above embodiments. Normally, the size adjusting piece 6 is accommodated in a concave groove 7 formed on the inner peripheral surface of the ring, and is kept in an unadjusted mode that is buried in the inner peripheral surface of the ring and does not affect the ring in terms of appearance or function. ing. First, the shaft 8 and the guide groove 9 are relatively moved so that the size adjusting piece 6 is slid in the direction of the arrow 201 and pulled out. Next, the size adjustment piece 6 is rotated in the direction of the arrow 202 around the shaft 8 as a rotation center, thereby completing the change to the adjustment mode in which the size adjustment piece 6 is held in a state of protruding from the inner peripheral surface of the ring.
[0028]
Even in this adjustment mode, the position of the size adjustment piece 6 on the inner peripheral surface of the ring is exactly the same as the position in the non-adjustment mode in which the size adjustment piece 6 is held along the inner peripheral surface of the ring.
[0029]
