Referring to FIG. 2, the force applied to the attachment plate 220 is transmitted to the ground through the tread 210 and the support 230. At this time, the mounting plate 220 and the stepping plate 210 and the support 230 is elastically deformed, thereby reducing the impact force due to a sudden load action to protect the human knee and the like. Therefore, the larger the elastic deformation amount to the upper and lower, the longer the impact time, the less the impact force due to the load action, the larger the elastic deformation is generally preferred.

Referring to FIG. 2, since the attachment plate 220 is rubber, it is elastically deformed when a load is applied, thereby prolonging the collision time and preventing suddenly large impact force from acting.

Referring to Figure 2, the tread 210 is a laminated reinforcement wood is a large amount of elastic deformation during the action of the load. On the other hand, since the support 230 is attached to each corner of the lower surface of the tread plate 210, when the load is applied to the center portion of the tread plate 210, the elastic deformation amount of the center portion is the maximum to minimize the impact force.

2 and 3, since the support body 232 is a thermoplastic polyurethane, the amount of elastic deformation during a load action is large. The elastic deformation amount is further increased due to the hole 232b formed in the support body 232. In addition, since the air cushion tube 234 inserted into and fixed to the support body 232 is a sealed tube filled with air, etc., the elastic deformation amount in the direction perpendicular to the circumference when a load is applied to the circumference of the air cushion tube 234. This becomes large so that the opposing periphery may be in contact. Therefore, the amount of movement to the lower portion of the support body 232 is located at the upper portion of the air cushion tube 234 during the load action, the impact time is reduced as the impact time is longer than the conventional design.

On the other hand, referring to Figure 2, if a large amount of load acts on the stepping plate 210 so that the deformation amount of the stepping plate 210 is large, the auxiliary support 240 is in contact with the ground so that the deformation amount of the stepping plate 210 exceeds the elastic limit Will be prevented. Even when the auxiliary support 240 is in contact with the ground, since the auxiliary support 240 is a thermoplastic polyurethane, a large impact force does not suddenly act on the user. The elastic deformation amount of the auxiliary support 240 is further increased due to the hole 240a formed in the auxiliary support 240.
