As described above, according to the present invention,
A ski plate is interposed between a ski boot and a ski, and the ski plate is flexed and deformed between a boot side mounting position where the ski boot side is mounted and a ski side mounting position where the ski side is mounted. Since it is shifted as much as possible, even if an abruptly changing load is applied from the ski boot, the load is absorbed by the ski plate and transmitted to the ski as a gradually changing load. Therefore, a sudden change in load transmitted from the ski boot to the ski can be reduced.

Since the pressure adjusting plate and the ski are slidably supported in the front-rear direction by the rear ski-side spacer, natural flex control according to the load from the ski boot is realized. be able to.
