PURPOSE:To obtain a simply structured clutch mechanism by vaking said clutch capable of switching transmission/non-transmisson of power depending upon the rotary direction of a motor or the like without utilizing spring force. CONSTITUTION:A clutch jaw 4 is so supported with a clutch jaw shaft 5 as to be able to universary move in the circumference direction at the end face of a flange part 2a of a disk 2 fixed to a spindle 1 with a fixing screw 3. The clutch jaw 4 is so formed as to be balanced in weight on right and left sides of the clutch jaw shaft 5 as a fulcurum. A clutch plate shaft 6 is provided being separated from the spindle 1 on its center line, and a clutch plate 7 is fixed to the clutch plate shaft 6 with a sixing screw 8. The clutch plate 7 is provided with an outer frame 7a of which inner diameter is slightly larger than the outer diameter of the flange part 2a of the disk 2. One or more notches are formed and arranged on outer frame 7a to switch the transmission/non-transmission of power depending upont the rotary direction of a motor or the like without utilizing spring force and to simplify the structure. |
