Driving apparatus having a joint member around which is wound an urging member

摘要

A driving appratus which includes a driving shaft which is linked to a driving member, a driven shaft which is connected with the driving shaft and which is linked to a driven member, a joint member which connects the driving shaft with the driven shaft so that a torque is transmitted from the driving shaft to the driven shaft while absorbing the eccentricity between both shafts and an urging member which is disposed to the joint member and which urges the joint member in the axial and rotational direction in regard to the both shafts. According to this improved driving appratus, the joint member rotates under the condition which is urged by the urging member in the axial and rotational direction in regard to the driving shaft and the driven shaft and transmitts the torque from the driving shaft to the driven shaft. Therefore, it is able to effectively absorb the vibration between the driving shaft and the driven shaft by the urging member and therefore it is able to prevent the generation of the uncomfortable noise and so on due to the vibration.
