摘要： A rock crushing device according to the present invention is designed to crush rocks by the use of the expansion pressure generated when an elastic expandable member of a cylindrical configuration is expanded by pressure fluid to be injected into looped pockets provided within the elastic member. The elastic member, made of rubber or similar materials, is provided tightly to cover around a metal shaft having a fluid passage to introduce pressure fluid into the looped pockets of the elastic member.
