PURPOSE: To transmit a large torque with a small clamping force and to conduct with only one clamping screw by incorporating a frictional member in an adjustable gearwheel for regulating a fixed gearwheel and a rotary position to the fixed gearwheel, and connecting the frictional member to be mutually overlappingly interengaging in a manner of a multi-drive clutch. CONSTITUTION: A connection by a tensionally connection of a fixed gearwheel 1 and a gearwheel 5 coaxial with and adjustable in rotational position thereof relative to the fixed gearwheel is conducted by a clamping plate 6 for forming a clamper and a clamping screw 7 passing through a central hole of the plate 6. The screw 7 is supported to the plate 6 at a screw head 8, and engaged at male threads with female threads of a hole of a shaft 2. A push ring 9 molded integrally is formed at an inside of the plate 6. The ring 9 press bonds the gearwheel 5 to the gearwheel 1 at the time of clamping the screw 7, thereby interengaging both the gearwheels via tensional connection by a frictional force. The member is clamped with the gearwheel 1 or the gearwheel 5 with screws 12, 13 to interengage the gearwheels 1, 5 in a clutch disk-like state to be formed of frictional disks 10, 11 formed in an overlapping range rear of the ring 9. |
