To suppress a temperature rise of an electronic device.SOLUTION: A case body is attached to a predetermined member by using a bracket, in a state where the case body is upright in a longitudinal direction. An intake port is formed in the lower part in the longitudinal direction of a wall part on the predetermined member side, and an exhaust port is formed in the upper part in the longitudinal direction. A control device is disposed between the intake port and the exhaust port. A cooling fan blows air so that the air taken in from the intake port is discharged from the exhaust port. An electronic device is located above the exhaust port in the longitudinal direction and the bracket is disposed on the external surface of the wall part and above the exhaust port in the longitudinal direction. The bracket has an exhaust passage at a position that does not match the electronic device and that is sandwiching the wall part.SELECTED DRAWING: Figure 10
【課題】電子機器の昇温を抑制する。【解決手段】筐体は、長手方向を立てた状態でブラケットにより所定の部材に取り付けられ、所定の部材側の壁部の長手方向の下部に吸気口が形成されると共に長手方向の上部に排気口が形成され、制御装置は、吸気口と排気口との間に配置され、冷却ファンは、吸気口から吸入した空気が排気口から排出されるように送風し、電子機器は、長手方向において排気口より上に配置され、ブラケットは、壁部の外表面であって長手方向において排気口より上に配置され、ブラケットは、壁部を挟んで電子機器と整合しない位置に排気通路を有する。【選択図】図10
