る釘打機。 A nail is provided with a grip part in the rear part of the housing and a striking cylinder which slidably accommodates a nail striking piston in the front part, and in which the main part of a main air chamber connected to a compressed air supply source is formed in the grip part. A striking machine, the above-mentioned striking cylinder,
The front end wall of the housing, both side walls continuous to the front end wall, and a first partition wall formed between the both side walls are formed into a substantially square cross section, and the striking piston is formed to have a substantially square cross section, At the rear of the striking cylinder, a striking piston return air chamber is defined by the first partition wall, both side walls, and a second partition wall formed between the both side walls behind the first partition wall. On the other hand, above the valve seat plate that closes the upper end of the percussion cylinder, a head valve having a substantially rectangular cross section that selectively communicates and shuts off the percussion cylinder with the main air chamber or the exhaust hole is biased rearward. A nailing machine characterized by being arranged in a vertical position.
