Zusammenfassung:To provide a jack capable of exerting a force with only one-hand wrist work in order to solve the problem that a jack for a large load which does not need a space of tool work usable in a narrow space is not available.SOLUTION: A cam-type jack comprises, in order to provide a mechanism for directly bearing phase deformation of the jack by an internal gear and enabling its operation only by a screw: a U-shaped base member f; a shaft member g attached to the base member; a plurality of cam members e supported by the shaft member so as to be rotatable and different in direction; a pair of cover members a and b covering the cam members and the base member from both sides; a shaft member c enabling opening/closing of the cam member sides of the cover members; a cover groove j-1 formed on an inside surface of each cover member and engaged with a cam groove formed on a cam surface of each cam member; and a rotation operation device member d in which one of the base member and the shaft member is rotatably supported and the other is screw-coupled.SELECTED DRAWING: Figure 1 【課題】 狭い空間で使える工具作業のスペースを必要としない、大荷重用のジャッキがない、したがって片手の手首作業程度で力が出せるジャッキを発案し、前述の課題を無くそうとするものである。【解決手段】 本発案は、内部の歯車がジャッキの位相変位を直接担い、その操作をねじだけで可能とする仕組みにするために、コの字状のベース部材fと、該ベース部材に取り付けられたシャフト部材gと、該シャフト部材に回転可能で向きが互い違いに支持される複数のカム部材eと、該カム部材と、前記ベース部材とを両側から覆う1対のカバー部材a,bと、該カバー部材の前記カム部材側を開閉可能とする軸部材cと、前記カバー部材のそれぞれの内側面に形成され、前記カム部材のカム面に形成されたカム溝部に係合するカバー溝部j-1と、前記ベース部材と前記軸部材のどちらかが回転可能に支持され他方がネジ結合される回転操作装置部材dで構成されていることを特徴とするカム式ジャッキで課題を解決しようとするものである。【選択図】図1
