PROBLEM TO BE SOLVED: To provide a tool socket which has an outer socket part and an inner socket part and prevents falling of the inner socket part.SOLUTION: A tool socket includes a cylindrical member (16), a moving member (18), an elastic member (20), and a restriction member (22). The cylindrical member (16) has an outer socket part (24) and a housing part (26), and the moving member (18) has an inner socket part (32) and a protruding part (36). The inner socket part (32) is provided so as to move in a cylinder axis direction in the outer socket part (24). The elastic member (20) biases the moving member (18) toward the one end side of the cylindrical member (16) in the housing part (26). The restriction member (22) has a C shape and is fitted into a groove part (26b) of the housing part (26). The restriction member (22) contacts with the protruding part (36) to restrict the moving member (18) from moving to the one end side.SELECTED DRAWING: Figure 2 |
