PROBLEM TO BE SOLVED: To provide an inexpensive vice device which increases force in a stable and efficient manner and achieves compactification.SOLUTION: A vice device includes: a body case having a fixed jaw and a movable jaw; a movable body; a screw rod; and a force-multiplication device included in the screw rod. The force-multiplication device includes: a piston rod having a second inclined part; a first body including multiple first inclined parts; a second body which is aligned with the first body while forming a certain space, faces the first body, and has slide parts; balls which are disposed among the piston rod, the first body, and the second body so as to contact therewith; and connection means. Each slide part has a restriction groove and is configured so that the balls can be moved to the radial outer side along the restriction groove by movement of the piston rod.SELECTED DRAWING: Figure 1 【課題】安定的に、且つ、効率良く増力させ、コンパクトにするとともに、安価なバイス装置を提供することを目的とする。【解決手段】固定ジョウと、可動ジョウを有する本体ケースと、可動体と、ネジ棒と、該ネジ棒に具備された増力装置とを備えたバイス装置において、増力装置は、第２傾斜部を有するピストンロッドと、複数の第１傾斜部を備える第１ボディと、第１ボディから一定の空間を有して対向配列され、スライド部を夫々備える第２ボディと、ピストンロッドと第１ボディと第２ボディとの間に当接されるボールと、連結手段とを備え、スライド部は、規制溝を有しており、上記ピストンロッドの移動により、ボールが上記規制溝に沿って径方向外方に移動可能に構成されていることを特徴とする。【選択図】 図１
