PURPOSE:To very easily control the connection of a clutch through its simple construction, by fitting a concaved flange to a protrusive flange, in which plural long holes are provided in a protrusive spherical body, providing driving protrusion movably engaged with said long holes in the side of the concaved flange and slidably mounting said concaved flange onto a driving shaft interposing a spring. CONSTITUTION:A clutch 15 can be roughly dividied into a protrusive flange 20 and a concaved flange 21. The protrusive flange 20, in which plural long holes 23, 23... are provided at an equal pitch angle on the surface of a protrusive spherical body 22, is fixed to a driven shaft 14 through a retainer screw 24. While the concaved flange 21, in which driving protrusions 26, 26 movably engaged with said long holes 23, 23 are provided on the surface of a concaved spherical body 25, is slidably mounted to a driving shaft 13. In short, placing the point end part of a screw 28 into a long groove 27 provided in a point end part of the driving shaft 13, the protrusive flange 20 and the concaved flange 21 are constituted so as to hole their fitted condition by the pressing force of a spring 19. |
