PURPOSE:To simplify an operation by making a negative pole side terminal of a battery conduct to a car body, and lighting automatically a head lamp, prior to an optical axis adjusting work. CONSTITUTION:When a car body B is thrown in and positioned in an optical axis adjusting process, a main arm 13 which has been in a holding state before that time turns by an action of a cylinder, and also an auxiliary arm 14 executes an expanding action by an action of a cylinder 17. When the main arm 13 turns and the auxiliary arm 14 expands, a pad 23 of an electric conductive bar 15 contacts elastically to a negative pole side terminal of a battery Ba and a part of the car body B, and a head lamp is lighted. In this regard, a head lamp switch of the inside of a car chamber is set to an on-state in advance. |
