Claims

[Scope of utility model registration request]

A cylindrical holder 2 having an outer diameter that can be inserted into a hole drilled in an object to be crushed such as a rock, and a through hole formed on the peripheral surface of the holder 2 that communicates the inside and outside of the holder 2. 3, a presser 5 fitted to the object to be crushed so as to move forward and backward; a rod 7 disposed at the center of the holding body and equipped with a pressure fluid passage 10 at the axial center; and a rod 7. A cylindrical elastic body that is fitted between the outer periphery and the inner periphery of the holder 2 and expands upon receiving the pressure of the pressure fluid from the pressure fluid passage of the rod 7, and applies the expansion force to the presser 5. An apparatus for crushing rocks, etc., comprising: 14.
