Title: POWER TRANSMISSION DEVICE
Abstract:
Provided is a power transmission device which is always capable of smoothly transmitting power, by effectively absorbing an impact as a result of the appropriate elastic member acting in response to the load of a torque load. This power transmission device is configured in a manner such that: a first rotating body 71 and a second rotating body 72 are positioned so as to be capable of coaxially rotating relative to a rotational center axis Lc; a single arc spring 75 having a large elastic deformation volume and a small elastic coefficient is interposed so as to be capable of biasing both the first rotating body 71 and the second rotating body 72 in the direction opposite the direction of rotation; first pressing projection parts 71p formed so as to project in the first rotating body 71 and second pressing projection parts 72p formed so as to project in the second rotating body 72 are provided at relative positions that overlap the trajectory of rotation; and rubber 76 having a small elastic deformation volume and a large elastic coefficient are interposed between the first pressing projection parts 71p and the second pressing projection parts 72p in a manner such that a gap exists therebetween.
