Claims

[Scope of utility model registration request]

A wrench main body with a regular hexagonal nut tightening part with an enlarged diameter at one end of a metal tube having a required length, and a handle locking part with the other end reduced in diameter, and an elastic member fitted into the wrench main body. The clamping body is made of a material, and the clamping body is cylindrical and has a flange-shaped friction resistance plate extending from the outer peripheral surface of one half of one end thereof, and extending from the wall surface to the inner peripheral surface of the clamping body for clamping. One end of the body is integrally provided with a cylindrical clamping part whose diameter is reduced at the end protruding toward the opening side, and the other end of the clamping body is placed first on the nut tightening part side of the main body of the wrench. A wrench for a spark plug, which is inserted through an opening, pushed into the inside of the reduced diameter end side, and frictionally locked inside the main body of the wrench by the friction resistance plate.
