Claims

[Scope of utility model registration request]

Han who supported movable Paul! A cam for accumulating pressure in a spring for closing a contact, and a ratchet integrally connected to this cam are coaxially provided, and the movable pawl is engaged with the ratchet by rotating the handle. In the air breaker, the cam is rotatably driven in the pressure accumulation direction of the energy storage spring, and a support pin that rotatably supports the movable pawl is connected to the handle by a fixing portion having a semicircular cross section formed at one end thereof. A spring is wound around the outer periphery of the support pin, and one end of the spring is engaged with the support pin, and the other end is engaged with the handle across the movable pawl. the movable pawl is pressed against the handle by the winding part of the spring, and the movable pawl is moved to the engagement position with the ratchet by the pressing force of the pawl straddling part due to the twisting between both ends of the spring. Pressed air breaker.
