PURPOSE:To enable incorporation of gears with a normal tool by using a standardized temporary clamping bolt and storing energy and releasing a scissors spring by changing relative angle position of a main gear and a sub gear. CONSTITUTION:A scissors spring 16 is disposed almost coaxially between a main gear 12 and sub gear 14 to constitute a scissors gear with a circlip type spring having a first and a second end portions. The first end portion is engaged with the main gear 12 and the second end portion is engaged with the sub gear 14. A screw hole 40 is provided on the main gear 12 or the sub gear 14, and a temporary clamping bolt 42 is made to screw in the second or the first end portion. And a means 34 engaging with a tip of the temporary clamping bolt and displacing the second or the first end portion in the circumferential direction is provided on the scissors spring 16. By this constitution, gears can be incorporated only with a normal tool. |
