Abstract:
PROBLEM TO BE SOLVED: To provide a securely holdable and smoothly usable exercise plaything not excessively slipping and catching by erecting a climbing up/down body with irregularity formed by several rows of spiral faces on the outer face. SOLUTION: A climbing up/down body 1 is formed of a hollow metal tube, preferably a rod-like rigid body. On the outer face of the climbing up/down body, several rows of spiral faces 2 are formed by known spiral working. The spiral faces is formed by connecting plural rows of protruding bars spirally extended, and the cross section orthogonally crossed to the axial line a is formed in a shape that a protruding face 20a and a recessing face 20b are alternately continued and equally placed. Several climbing up/down bodies 1 are supported and erected by a supporting means. Thus the plaything can be stably placed and one can safely climb up/down by the spiral face 2 as not excessively slipping and catching.
