Claims

[Scope of utility model registration request]

A piston that is integrally constructed with a driver that strikes a stop or the like, a cylinder that houses the piston and is slidable, and a cylinder head that is integrally constructed with the cylinder and forms a passage for discharging compressed fluid from the upper part of the piston to the outside. In the driving machine, the driving machine has a housing B that constitutes a passage and a narrow path of the cylinder head, and a cylinder sleeve that is slidable circumferentially on the cylinder and that functions as a valve that controls the inflow of compressed fluid into the inside of the cylinder. The sleeve forms a compressed fluid chamber, and the cylinder head and housing B form a narrow passage when the cylinder is in the lower position and a wide passage when it is in the upper position, and the cylinder integrated with the cylinder head is forcibly returned to the lower position. 1. An output structure for a driving machine, characterized by having a spring for driving.
