Claims

[Claims for Utility Model Registration] (1) Two semicircular arc shapes having ratchet teeth on the outer periphery and spaced apart from the center of the plane toward the outer periphery so as to have a point-symmetric positional relationship with respect to the center of the plane. a gear having a hole, a gripping part for gripping a bolt head or a nut, a sloped part of the gripping hardware, and a central part of the gripping hardware, and the central part of the gripping hardware is arranged with a gap in the semicircular hole. The fitted gripping hardware, the fixed hardware having a fixed hardware inclined part and in which the gripping hardware inclined part and the fixed hardware inclined part are fitted, the gear, the gripping hardware, and the fixed hardware are stored, and the grip part is assembled. A ratchet spanner comprising a main body having a main body. (2) The ratchet spanner according to claim 1, wherein the gear has a cylindrical hollow part in the center thereof which is larger than the outer diameter of the threaded part of the bolt.
