A mechanism for an open bolt type air gun includes a trigger that is pulled with a bolt in its retracted position. The mechanism includes a sear or an inner safety and a trigger bar. The sear is located behind and below the bolt and has a projection to come into contact with a locking projection of the bolt. The inner safety is located below the bolt and has a projection to come into contact with the locking projection of the bolt. A first trigger bar is located below the sear and has a bolt contact part which extends upward at its front end and comes into contact with a cam part of the bolt and a locking projection to lock the sear. A second trigger bar is located below the inner safety and forward of the first trigger bar and has a locking projection to lock the inner safety.
