That is, when the thick elastic piece 29a having the smallest deflection is perpendicular to the ground by the operation of the adjusting knob 27a as shown in (a) and (b) of FIG. Even if it is transmitted to 21a), the elastic force is not generated at the bottom surface by the thickest elastic piece 29a having the least bending, but at this time, two

elastic pieces

29c and 29d having different thicknesses are elastic members 21a. The elastic member 21a is stretched according to the elasticity of the

elastic pieces

29c and 29d by being positioned at the upper portion.

However, as shown in (a) and (b) of FIG. 5c, when the elastic piece 29e having the thinnest thickness and the high bending angle is erected perpendicularly to the ground by the operation of the adjusting knob 27a, the user's weight is the elastic piece 29e. ) As it is transmitted as it is to have the elasticity proportional to the elastic piece (29e) in the bottom surface, in this case, so that the ends of the two elastic pieces (29b, 29c) of different thickness are located on the upper portion of the elastic member (21a) By doing so, the elastic member 21a is stretched according to the elasticity of the

elastic pieces

29b and 29c.

Another embodiment of the present invention is a material having a constant curvature, which is hard to be bent as the thickness is thick, but is thinner as the thickness is used to be bent well, and vertices of the elastic control members 22a to 22d shown in FIGS. 4A to 4C. When standing vertically to prevent the impact is transmitted directly to the sole of the user to improve the wearing comfort, for example, the number of elastic pieces (29a ~ 29e) with different thickness is five, but the number is limited An odd number is preferred, such as three, five, seven, and the like.
