A vibration preventing device in an intermittent driving mechanism for intermittently operating a driven member having a specified mass with a motor, includes an elastic body interposed between an operating member and a stationary member facing thereto which are disposed in a motor power transmission system, and a friction surface formed between the elastic body and the operating member or between the elastic body and the stationary member, whereby at the time of starting the motor, the load on rotation of the motor is gradually increased by elastic deformation of the elastic body.
