  The bottom wheel 2 is slidably fitted to the center rod 100 and has a hollow cylindrical wheel body 21 to which an umbrella bone (not shown) is rotatably connected, and the axis L direction with respect to the wheel body 21. And a hollow cylindrical actuating member 22 provided so as to be slidably connected vertically.

  As shown in FIGS. 1 and 2, the actuating member 22 defines a fitting space that surrounds the potter's wheel body 21 and a locking piece 154 described later, and the peripheral wall portion 221 that surrounds the potter's wheel body 21 is fitted. It has a space-side inner peripheral surface 222. The actuating member 22 is provided with a first locking portion 223 extending inward from the inner peripheral surface 222 into a protruding shape. Further, the first locking portion 223 has a guide inclined surface 224 that is inclined so that the extending outer surface becomes thinner toward the lower side, that is, the fitting space becomes larger in diameter toward the lower side. Is provided.

  As shown in FIGS. 1 and 2, the handle 1 has a handle body 10 that holds the lower end portion 101 of the center rod 100, and the handle body 10 has one end in the axis L direction opened upward and the other end Is closed and has a substantially U-shaped bottomed cup shape. The bottom wall portion 13 of the closed end and the bottom end of the middle rod 100 rise from the bottom wall portion 13 so as to surround the axis L. The tip of an umbrella bone (not shown) that is inserted between the inner wall portion 12 that defines the holding space 120 that is inserted into and holds the portion 101 and the bottom wall portion 13 and is folded between the inner wall portion 12 and the inner wall portion 12. ) And an outer wall portion 11 that forms an accommodation space 110 in which the second wall 11 enters.

  In this example, the inner wall portion 12 includes an outer wall 14 that is formed by continuously rising upward from the bottom wall portion 13, and a holding space that is coupled to the outer wall 14 and holds the lower end portion 101 of the intermediate rod 100 inside. The inner wall 15 defines 120. In this example, screws 141a and 151a that can be engaged with each other are formed on the inner peripheral surface 141 of the outer wall 14 near the inner wall 15 and the outer peripheral surface 151 of the inner wall 15 near the outer wall 14, respectively. 14 and the inner wall 15 are joined together.

  On the upper end 152 of the inner wall 15, an upper flange 153 projects outward in a radial direction substantially perpendicular to the axis L direction so as to come into contact with the upper end surface 142 of the outer wall 14. It is formed so that it can be locked. Further, a plurality of (four in the illustrated example in FIG. 2) split grooves 156, 156,... Are vertically long (in the direction of the axis L) from the upper end 152 of the inner wall 15 at a predetermined interval in the circumferential direction. Are provided such that a plurality of elastically deformable locking pieces 154, 154,... That can swing in the radial direction by being notched in the direction are extended upward.
