するものである。 In the figure, an annular clutch body 1 is divided into three clutch pieces 5, 5, . . . by radial dividing surfaces 3, 3, . . .
It is slidably supported in the radial direction by a boss portion 9 that is fixed to a drive shaft 7 that is driven by. That is, the clutch piece 5 is held between the end of the drive shaft 7 and a boss 9 into which a disc-shaped washer 11 is fitted and screwed onto the end. The boss portion 9 is provided with guide rods 17 having a radial rectangular cross section and protruding in three directions at equal intervals on a boss shaft 15 provided around a screw hole 13.
An edge plate 19 is integrally formed on the outer surface of the guide rod 17 in a shape that projects from the periphery of the guide rod 17. A stop portion 21 protrudes and is formed in one piece. The clutch piece 5 is provided with a notched groove 23 that slidably engages with the guide rod 17, and the edge of the notched groove 23 engages with a locking part 21 to restrict the sliding range of the clutch piece 5. A rectangular locking hole 25 larger than the locking portion 21 is cut out. The divided surface of the clutch piece 5 has a notch recess 27 that can be engaged with the tip of a flat tool such as a flathead screwdriver, and smaller notches 2 are provided at both edges of the arc-shaped notch recess 27.
It is formed in a shape with 9. clutch body 1
A spring groove 31 opening on the side surface is provided along the outer periphery of the clutch member 5, and a coil-shaped spring 33 is engaged inside the spring groove 31 to press and urge the clutch piece 5 toward the center. A clutch drum 35 provided close to the outer periphery of the clutch piece 5 has a driven shaft 37 fixed to the center thereof, is rotatably supported on the outer periphery of the drive shaft 7 via a bearing 39, and is integrally formed on the outer periphery. Power is transmitted through a chain (not shown) that engages the sprocket 41.

As the clutch piece 5 rotates, the clutch piece 5 supported by the boss portion 9 also rotates, but at low rotations, it is pressed by the bullet 33 and does not contact the clutch drum 35, so that the driven shaft 37 does not rotate. When the engine speed increases and reaches the specified speed,
As the centrifugal force increases, the clutch piece 5 is pressed against the outer clutch drum 35 against the bullet 33, the clutch drum 35 rotates together with the clutch piece 5, and the driven shaft 37 rotates. In the event that the clutch drum 35 is damaged, the locking hole 25 of the clutch piece 5 is locked with the locking part 21 of the boss portion 9, so that the clutch piece 5 will not come off and scatter. Also, when assembling these three clutch pieces 5 to the boss portion 9, the bullet 3 is inserted into the spring groove 31 of the three clutch pieces 5.
3, engage the tip of the flathead screwdriver with the notch 29 of the notched recess 27, and rotate the flathead screwdriver 90 degrees, so that the three clutch pieces 5 are spread out. Next, the guide rods 17 of the boss part 9 are respectively engaged with the notch grooves 23 of the clutch piece 5, and the boss part 9 is screwed onto the tip of the drive shaft 7 while the clutch piece 5 is held between the washer 11 and the boss part 9. It matches.
