<P>PROBLEM TO BE SOLVED: To provide a rotation body operating tool equipped with antislip structure which can surely prevent the slip out of a handle while achieving a relatively reduced cost, in consideration of the actual rotating operation of the handle with a general valve handle wrench. <P>SOLUTION: The rotation body operating tool 1 includes a long rod operation lever 2, and a hook part 3 provided on one longitudinal end side of the operation lever 2 for gripping a rotation body 10, the hook part 3 being constituted of a base portion 6, and an arm 4 and an arm 5 extending in parallel from the base portion 6 along its radial direction. Herein, rubber layers 7 serving as antislip structure during the rotating operation of the rotation body 10 are formed at least on the surface of the arm 4 and on the surface of the arm 5 in their ranges where they face each other and can abut on the rotation body 10, and on the surface of the base portion 6 in its range where it extends from the base end of the arm 4 to the base end of the arm 5 and can abut on the rotation body 10. <P>COPYRIGHT: (C)2012,JPO&INPIT |
