Abstract
A driving apparatus includes a motor, an output unit, and an elastic transmission mechanism. The transmission mechanism is disposed between the motor and the output unit to relieve shocks applied to the driving apparatus when operation of the output unit is obstructed. The elastic transmission mechanism includes a first elastic member which absorbs a first shock and second elastic member which absorbs a second shock different in torque from the first shock.
