A meter unit includes a step motor, a gear, a braking spring and a case. The gear has a gear body and a rotation shaft. The braking spring urges the gear in a direction of an axis of rotation of the gear. The case accommodates the step motor, the gear body, a part of the rotation shaft, and the braking spring therein. The braking spring has a shape through which the first part of the rotation shaft passes. A first face of the gear body is formed with a recessed portion which accommodates the braking spring. A first part of the case supports a second face of the gear body. A second part of the case is configured to press the braking spring so that entire part of the braking spring is accommodated in the recessed portion. |
