Claims

[Scope of utility model registration request]

(1) a housing, a rotating shaft rotatably supported by the housing; - a drive shaft connected to the rotating shaft so as to be slidable relative thereto and having a socket at its tip; an input shaft that is rotatably supported on an axis and has a sun gear formed on its outer periphery; a first one-way rotation clutch that transmits rotation to the rotating shaft only when the input shaft rotates forward; and a first one-way rotation clutch that is engaged with the sun gear. a planetary gear fixed to the housing concentrically with the input shaft and meshing with the planetary gear; and a fixed internal gear rotatably supported by the housing concentrically with the input shaft and the fixed internal gear a movable internal gear that is given a difference in the number of teeth and meshes with the planetary gear;
The movable internal gear includes a second one-way rotation clutch that transmits rotation to the rotation shaft only when the movable internal gear rotates in the normal direction, and a drive motor that rotates the input shaft in the forward and reverse directions, and the planetary gear is formed in a thin-walled cylindrical shape. A nut runner is made by filling the hollow inside of this planetary gear with an elastic material.

(2) Two of the planetary gears are arranged on the diameter line of the sun gear, and two of the movable internal gears are arranged with respect to the fixed internal gear.
The nut runner according to claim 1 of the utility model registration claim, which has a difference in the number of teeth.
