When the brake plate presser part 15 is locked at a fixed position and the brake of the leg ring 1 is released, the brake plate presser part 15 is pulled upward to release the brake plate 14. Apart from the ring body 12, such a structure stops the leg 1 by the contact of the brake plate 14 and the ring surface of the ring body 12, however, the friction between the brake plate 14 and the ring surface of the ring body 12. Coefficient is Sai Therefore, no good braking effect, when an external force is applied, often Watai 12 rolls.
