Abstract
In a power transmission apparatus, a driving rotary body is rotated by power from a driving device. A driven rotary body includes a driven rotary member attached to a rotating shaft of a driven device and a holding plate attached to the driven rotary member. A damper mechanism includes a cylindrical elastic member attached to the driving rotary body and a connecting member which is engaged in the elastic member to be movable forward/backward. At least one rotation transmission member is attached to the connecting member, has one end connected to the driving rotary body through the damper mechanism and the other end separably connected to the driven rotary body, and transmits rotation of the driving rotary body to the driven rotary body. A preset load setting member is mounted between the driven rotary body and the connecting member to elastically deform the rotation transmission member, thus applying a preset load.
