The invention provides a relay device and a power supply device for a vehicle, that is, a relay device in which freezing is difficult to occur at a contact and a power supply device for a vehicle in which malfunction is difficult to occur in a cold period. The relay device (33) includes a first contact (A331) and a second contact (A332), a first conductor (331) electrically connected to the first contact, a second conductor (332) electrically connected to the second contact, a housing (339) housing the first contact, the second contact, the first conductor, and the second conductor, and heat transfer members (336A, 336B) having a higher thermal conductivity than the housing. Furthermore, heat transfer members (336A, 336B) are provided from the outside of the housing (339) to the inside of the housing (339), and are in contact with at least one of the first conductor (331) and the second conductor (332).
本发明提供继电器装置及车辆的电源装置,即在触点难以发生结冰的继电器装置以及在寒冷时期难以发生故障的车辆的电源装置。继电器装置(33)具备第一触点(A331)及第二触点(A332)、电连接有第一触点的第一导体(331)、电连接有第二触点的第二导体(332)、容置第一触点、第二触点、第一导体及第二导体的壳体(339)以及热导率高于壳体的传热部件(336A、336B)。并且,传热部件(336A、336B)从壳体(339)的外部设置到壳体(339)的内部,并且与第一导体(331)及第二导体(332)中的至少一者接触。
