A model gun with automatic bullet supplying mechanism comprises a pressure accumulating chamber from which a gas leading passage extends, a slider movable along a barrel structure, a pressure receiving portion fixed in the slider at the back of the barrel structure, a movable member provided with first and second inner spaces and arranged at the back of a bullet holding chamber, a passage connecting portion provided at the outside of the movable member for connecting the gas leading passage to the first and second inner spaces in the movable member, and a movable valve provided in the passage connecting portion. The movable valve is operative selectively, during a period in which the gas leading passage is connected through the passage connecting portion to the first and second inner spaces in the movable member, to cause gas derived through the gas leading passage from the pressure accumulating chamber to act through the first inner space in the movable member on a sham bullet in the bullet holding chamber and to shut off gas flow to the bullet holding chamber through the first inner space in the movable member from the gas leading passage so that the gas derived through the gas leading passage from the pressure accumulating chamber acts through the second inner space in the movable member on the pressure receiving portion to cause the pressure receiving portion to move back in company with the slider. |
