A hand is provided which is capable of increasing not only the operation stroke of a pair of gripping members but also gripping force of the pair of gripping members. The hand according to the present invention is provided with first and second sliders (11, 12), a driving source (3), a rotating plate (5), a first clamping link (31), and a second clamping link (32). Of these components, the first and second sliders (11, 12) are provided on a hand body (1) so as to be linearly movable in opening and closing directions and the driving source (3) is provided in the hand body (1). The rotating plate (5) is rotatably driven by the driving source (3). The first clamping link (31) is linked with the rotating plate (5) so as to be only rotatable on a first shaft (41), and is linked with the first slider (11) so as to be only rotatable on a second shaft (42). Moreover, the second clamping link (32) is linked with the rotating plate (5) so as to be only rotatable on a third shaft (43), and is linked with the second slider (12) so as be only rotatable on a fourth shaft (44). The first and second sliders (11, 12) move linearly in the opening and closing directions by making the driving source (3) rotate the rotating plate (5). |
