As a result, it is absorbed by the cushioning member 2 and the exercise operation can be favorably performed with an appropriate elasticity performance.
Further, when the player falls over for some reason and hits the head, elbow, knee, waist, or the like, the shock absorbing member 2 carries the impact with a moderate softness. At this time, an impact acting on a point on the floor plate 5 caused by the competitor is diffused in the joist deck member 3 which has high rigidity and is spread over substantially the entire surface of the floor surface, Then, the impact member 2 is
At any position on the floorboard 5,
Almost the same elastic performance and soft performance are maintained.

Then, the large load is received in a planar manner by the highly rigid joist deck member 3 and acts on a large number of buffer members 2 in a distributed manner over a large area, so that the buffer member 2a in the portion becomes more than a predetermined amount. Deform.
Thereby, the bent portions 7a, 7a of the regulating member 7 abut on the lower plate 2b to prevent further deformation of the cushioning material 2a, and a large load acting on the deck member 3 is reduced via the regulating member 7. Acts directly on the large pulling member 13 and has high rigidity
