<P>PROBLEM TO BE SOLVED: To simplify a structure of a rotating direction reversing unit, and to provide stable reversing action. <P>SOLUTION: An intermediate shaft 7 extending in a direction orthogonal to a fixed shaft 1 is provided around the fixed shaft 1, bevel gears 8, 9 respectively rotatably attached with a first input member 2 and an output member 4 on both sides of the intermediate shaft 7 are provided on opposing faces of the first input member 2 and the output member 4, and an intermediate bevel gear 10 engaging with the bevel gears 8, 9 is rotatably attached to the intermediate shaft 7 as a second member 3. In a state of rotating the first input member 2, when a revolution speed (a rotation speed of the intermediate shaft 7) of the intermediate bevel gear 10 of the second input member 3 is changed to about half of a rotation speed of the first input member 2, a rotating direction of the output member 4 is reversed. By this, a conventional spring clutch can be eliminated, and simplification of the structure and stabilization of the reversing action can be carried out. <P>COPYRIGHT: (C)2011,JPO&INPIT |
