Claims

[Scope of utility model registration request]

A flexible ring fitted on the rod is held between flanges provided at each tip of a hollow shaft and a rod slidably penetrated through the hollow shaft, and the flexible ring is flexible as the rod moves. In a device for crushing rocks by the expansion force of the ring that is generated when the body ring is compressed in the axial direction, a back-up spring is provided on the conical surfaces formed on the opposing surfaces of the hollow shaft and each tip flange of the rod. A rock crushing device characterized in that a flexible ring is sandwiched between both backing springs that collide with each other, and a spacer is interposed between adjacent flexible rings.
