Abstract: In an electronic control unit, an electronic device including guide members at ends is installable to a rack along an installation direction orthogonal to a thickness direction. A movable member is disposed in the rack and holds a cooling plate to be movable in the thickness direction. The guide member includes a guide groove to receive a protrusion of the movable member. The guide member has an inclined portion, as a part of the guide groove, inclined relative to the installation direction and a holding portion at an end in the installation direction. The electronic device is configured to cause the movable member to move toward the electronic device by guiding the protrusion from the inclined portion toward the holding portion, after the electronic device is placed in a placement position to face the cooling plate, thereby mounted on the rack.

Abstract: A component mounting part has a width shorter than a distance between guiderails. Backside projected parts protrude in a width direction from the component mounting part at a case-backside end. A width K2 which is a sum of a width of the component mounting part and widths of the backside projected parts is greater than a distance G1 between the guiderails. A clearance is formed between the circuit board and the heat conduction member when the backside projected parts are supported by the guiderails. A distance G3 from an insertion slot to an end of the guiderail on the case backside, is shorter than a distance K4 from an end of the circuit board on the side of the insertion slot to an end of the backside projected part on the side of the insertion slot.

Abstract: A fixing device has a body case therein defining a housing chamber in which an object is housed and a cover that covers the housing chamber. The body case has one of a groove and a protrusion that engage with each other. The object has an other one of the groove and the protrusion.
