摘要

The weight and cost of a steerable ski can be reduced by providing a steerable ski formed of resin as a whole and which includes a hollow portion. The hollow portion is filled with a foamed material as required. Accordingly, the height in cross section of the steerable ski can be increased to thereby increase the modulus of section. As a result, the wall thickness of the steerable ski can be reduced to thereby prevent an increase in the weight and cost.
