PROBLEM TO BE SOLVED: To provide a socket holder for performing positioning by abutment means by rotatably adjusting a positioning block in particular.SOLUTION: The rotary positioning socket holder includes a base, a positioning plate, and a plurality of positioning blocks. The base has rails projected on opposing surfaces, a connection plate is installed between the lower sides of the rails, and a positioning recess is formed in the connecting plate. The positioning plate is fitted in the positioning recess of the base, and an abutment part is provided to project between the rails from the lower side. The positioning block is installed on the rail of the base so as to be rotatable and slidable in the longitudinal direction of the rail. The positioning block is brought into contact with the abutment part via a bottom part and with the inner surfaces of the two rails via upper surface both sides, thereby constituting three abutment points. The positioning block is positioned on the base and the positioning plate by the abutment points.SELECTED DRAWING: Figure 1 |
