The invention provides a relay device and a power supply device for a vehicle, i.e., a relay device capable of operating even when a contact is frozen, and a power supply device for a vehicle capable of reducing malfunction in cold weather. A relay device (33) is provided with: a first contact (A331) and a second contact (A332); a drive mechanism (334) that causes the first contact (A331) and the second contact (A332) to approach or separate from each other; a first conductor (331) electrically connected to the first contact (A331); a second conductor (332) electrically connected to the second contact (A332); and a contactless relay (336) and an electric heating body (337) connected between the first conductor (331) and the second conductor (332). The electric heating body (337) is disposed so as to be able to heat at least one of the first contact (A331) and the second contact (A332).
本发明提供继电器装置及车辆的电源装置,即,即使在触点发生了冻结的情况下也能够进行工作的继电器装置以及在寒冷时能够降低工作不良的车辆的电源装置。继电器装置(33)具备:第一触点(A331)及第二触点(A332);驱动机构(334),使第一触点(A331)与第二触点(A332)接近或者分离;第一导体(331),与第一触点(A331)电连接;第二导体(332),与第二触点(A332)电连接;以及无触点继电器(336)及电热体(337),连接于第一导体(331)与第二导体(332)之间。并且,电热体(337)配置为能够对第一触点(A331)及第二触点(A332)中的至少一者进行加热。
