Document Type and Number:
Japanese Patent JP3569655
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power tool for moving an element corresponding to an object, for example, for moving a nut to be screw-fitted in a bolt and a bolt head and its moving method.
SOLUTION: They are a plurality of screw members which are arranged at an interval mutually around an axial line and can be screwed into an element to move the element in the direction of axial line relative to an object. A drive device including the screw members 9 having a first end part 10 for acting mutually with the object and a second end part 11 on the opposite side each and an action drive and a reaction drive which are arranged coaxially with an axial line A mutually and can rotate in the opposite direction is provided. By providing the drive device in which a drive 5 on one side meshes with an outer circumference of a ring of the screw member 9 and a drive 3 on the other side meshes with an inner circumference of the ring of the screw member 9, the drive device rotates in the opposite direction, the screw members rotate in the same direction, and as a result, the element is moved in the direction of axial line when a power tool operates.
