PROBLEM TO BE SOLVED: To improve operation ability when attaching and detaching a weight member, and surely prevent falling of the attached weight member.SOLUTION: An inside member 40 is rotated in a clockwise rotation direction. By rotation of the inside member 40, an outside member 38 is rotated with the inside member 40 via a rotation force transmission mechanism 42, and an engagement salient part 48 is positioned on an engagement position P1 where the engagement salient part cannot rotate in the clockwise rotation direction. When the inside member 40 is further rotated in the clockwise rotation direction, only the inside member 40 is rotated, and the inside member 40 moves in a shaft center direction of an engaging hole 50 in the outside member 38. A tip end 5204 of the inside member 40 contacts a bottom wall 3410 of an attachment hole part 14, and by rotation of the inside member 40, the engagement salient part 48 is, by pressure, brought into contact with a partition wall 36 being a wall part of a sole 22, and a weight member 16 is positioned on a lock position where detachment from the attachment hole part 14 is impossible.SELECTED DRAWING: Figure 12 |
