A starter for starting an engine in a vehicle is disclosed. The starter includes a motor and an output shaft that rotates by receiving torque from the motor. The starter also includes a pinion movable body that includes a pinion for transmitting the torque of the motor to a ring gear of the engine. The pinion movable body is provided on an outer circumference of the output shaft integrally with the pinion in a manner allowing movement along an axial direction thereof. The pinion is pushed towards the ring gear by a pinion-pushing means. A motor current-supply means turns ON and OFF energizing current flowing to the motor. A shock absorbing device is disposed on a torque transmitting path transmitting the torque of the motor to the pinion.
