摘要： An objective of the invention is to provide a work apparatus in which the maximum value of the force acting on a work object is unchanged even when the size of the object varies, the work apparatus not exerting force in excess of a prescribed value. The work apparatus is provided with a first member (1) and a second member (2), at least one of which is moveable, and is additionally provided with a work part (3) operated by movement of the first member (1) or the second member (2). Either the first member (1) or the second member (2) is furnished with a mobilization part (4) and a mobilized contact part (5), while the other is furnished with a contact receiving part (6). When the operating resistance of the work part (3) reaches a prescribed value, the mobilized contact part (5), having been mobilized in a direction different from the direction of movement prior to contact due to deformation of the mobilization part (4), comes into contact against the contact receiving part (6), and in this state of contact of the mobilized contact part (5) against the contact receiving part (6), force further applied to the moveable first member (1) or the second member (2) is not transmitted to the work part (3).
