Claims

[Scope of utility model registration request]

The assembled nut, which can be divided vertically, is held inseparably at all times by a lock piston with a holding means, and the combustion gas pressure of the gunpowder is applied to the working chamber formed on the assembled nut side of the lock piston. In a separation nut in which the lock piston is propelled until the holding means separates from the held part of the assembled nut, the lock piston is provided so as to be able to freely stroke, and the lock piston is provided with a restriction that allows communication from the working chamber side to the back of the lock piston. A separation nut that formed a passage.
