To provide an air chuck which has strength for stably maintaining connection with a valve and can reduce an outer diameter.SOLUTION: An air chuck includes: an engagement pin 103; a guide cylinder 102 which can slide and move between an engagement position for engaging with a groove so as to sandwich a valve from both side surfaces and a release position for releasing an engagement state, and has a guide hole for protruding both end parts of a pair of engagement pins to an outer side from an approximately cylindrical outer circumferential surface; a washer 105 which supports both ends of the pair of engagement pins; a compression spring 104 which elastically biases the washer to the pair of engagement pins; and a slide outer cylinder 106 which has an engagement part positioned opposite to the compression spring in a center axis direction with respect to the engagement pin on an inner circumferential surface, and moves the engagement pin to the release position. The engagement pin does not abut on an inner circumferential surface of the slide outer cylinder when the engagement pin is positioned in the release position in the guide hole.SELECTED DRAWING: Figure 2

    【課題】安定的にバルブとの接続を保持できる強度をもち且つその外径の小径化を実現することのできるエアチャックを提供する。【解決手段】エアチャックは、係合ピン103と、バルブを両側面から挟むように溝と係合する係合位置と、係合状態を解除する解除位置との間をスライド移動可能にするとともに、該一対の係合ピンの両端部を略円筒形状の外周面よりも外側に突出させるガイド孔が形成されたガイド筒102と、一対の係合ピンの両端を支持する座金105と、座金を一対の係合ピンに対して弾性的に付勢する圧縮バネ104と、その内周面上の係合ピンに対して中心軸方向において圧縮バネと反対側に位置する係合部を有し、係合ピンを解除位置まで移動させるスライド外筒106とを備え、係合ピンは、ガイド孔内における解除位置に位置する状態においてスライド外筒の内周面に当接しない。【選択図】図2
