るようにしたことを特徴とするさく岩槻。A cylinder into which a piston for striking the mounting rod is slidably inserted; a cylindrical exhaust muffler that fits around this cylinder and holds the cylinder so that it can be moved back and forth via a spring; and a cylindrical exhaust muffler is integrated in the front part. In the Iwatsuki that is equipped with a retaining member formed in the same manner, striped seats are provided at the front and rear ends of the spring, and the cylinder and the retaining member are normally provided with a front surface of the front spring seat and a rear spring seat. A locking portion is provided in contact with the rear surface, and when the exhaust port of the cylinder moves the holding member back against the cylinder to compress the spring, the front spring seat is secured and moved by the locking portion of the holding member. The Iwatsuki is characterized by having an opening at a position where the opening is closed by a spring seat.
