PLASTIC-MADE ROTATIONAL OPERATING TOOL

摘要

PROBLEM TO BE SOLVED: To provide a plastic made rotational operating tool capable of favourably and easily rotationally operating a plastic made screw member such as a nut, etc. SOLUTION: A rotational operating tool 1 is a plastic made integral mold constituted of a tool main body 6 and an operating lever 7 connected to its base end part. A fulcrum part 9 to be irregularly engaged with a recessed part 5 formed on an outer peripheral surface 4 of a rotationally operated part 3 of a plastic made screw member 2 is formed on a head end part of the tool main body 6. A working point part 8a to be frictionally engaged with the outer peripheral surface 4 of the rotationally operated part 3 in a state where the fulcrum part 9 is irregularly engaged with the recessed part 5 is formed on a base end part of the tool main body 6. It is possible to rotate the plastic made screw member 2 in the specified direction R by revolutionally operating the operating lever 7 in a direction Ra to pressurize the working point part 8a on the outer peripheral surface 4 of the rotationally operated part 3 around an engaged part of the fulcrum point 9 of the tool main body 6 and the recessed part 5 of the rotationally operated part 3 as its center.
