Abstract: A needle carrier (100) includes a pinching attachment (20) having a pinching arm member and a pinching arm support portion on which the pinching arm member is disposed and configured to pivotably support the pinching arm member around a first axis line, a needle carrier body (10) on which a grip portion (112) is formed, a pinching arm opening/closing drive portion (30) having a pinching operation lever (31) and a pinching operation transmission part, and a pinching arm pivotal drive portion (40) having a pivotal operation wheel (41) and a pivotal operation transmission part, and the pinching arm opening/closing drive portion (30) includes an axial dimension expansion/contraction spring (35) configured to attenuate a pinching operating force input from the pinching operation lever (31) and pinch the pinching portions.

Abstract: A gripper is capable of efficient gripping in a narrow space. A gripper has a first arm and a second arm which can open and close about a supporting pin and are configured so that opposing surfaces formed by opening and closing the first and second arms form the holding portion. The gripper is characterized in that a pair of clipping members is connected with the holding portion of the first arm and the second arm so that the pair of clipping members can rotate about support points relative to the holding portion, and in that a rotation manipulation portion is connected with the clipping members at a position offset from the support points and applies a displacement to the position to which the rotation manipulation portion is connected.
