To provide a load drive device capable of reducing the number of components of at least a part of a load drive circuit, while reducing the mounting area and restraining weight increase.SOLUTION: A load drive device includes a main relay 20 and a switching relay 30, and is configured so that a first load 11 and a second load 12 are connected with the switching relay 30, respectively. With such an arrangement, while controlling on-off of current supply from an electric power supply 50 by means of the main relay 20, the power supply destination can be selected from the first and second loads 11, 12 by means of the switching relay 30. With such a load drive device, not only actuation of the first load 11 can be controlled, but also actuation of the second load 12 can be controlled. Various components used for actuation of the second load 12 can be shared with various components used for actuation of the first load 11.SELECTED DRAWING: Figure 1

    【課題】負荷駆動回路のうちの少なくとも一部の部品点数を削減でき、搭載エリアの削減および重量増加の抑制を図ることができる負荷駆動装置を提供する。【解決手段】メインリレー20と切替リレー30とを備えると共に、第1負荷11と第2負荷12とをそれぞれ切替リレー30に接続した構成とする。これにより、メインリレー20によって電源50からの電流供給のオンオフを制御しつつ、切替リレー30によって電流供給を行う先を第1負荷11と第2負荷12のいずれにするかを選択できるようにしている。このような負荷駆動装置により、第1負荷11の作動を制御できるだけでなく、第2負荷12についても作動を制御することができる。そして、第2負荷12を作動させるために用いる各種部品について、第1負荷11を作動させるために用いる各種部品と共通化させられる。【選択図】図1
