Abstract: A vehicular antenna device includes an antenna portion having an antenna element, and a frame accommodating a heat generation member. The vehicular antenna device is configured to be attached to an attachment portion of a vehicle. The frame includes a first space portion having a cylindrical shape and defining a first space, the first space portion being exposed to an outside air in a condition where the vehicular antenna device is attached to the vehicle. The heat generation member is located along a second surface of the frame that is a reverse side of a first surface defining the first space. The antenna portion is detachable from the frame.

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 housing-securing unit for a vehicle includes: a housing in which a circuit board is to be housed; and a bracket through which the housing is mounted to the vehicle. A holding pin having a column shape is provided on a side surface of the housing. The bracket has a side support component in which a through hole is formed for fitting the holding pin. The holding pin has an inclined approach surface having a height that is increased as extending in an assembling direction, and a holding surface formed to regulate the side support component from moving in the assembling direction and to oppose an inner peripheral surface of the through hole when the holding pin is fitted to the through hole. A height of a top part of the holding surface is more than or equal to a height of a top part of the inclined approach surface.

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. The groove includes a receiving portion and a positioning portion. The receiving portion extends in an inserting direction in which the object is inserted into the housing chamber. The positioning portion extends in an intersecting direction intersecting with the inserting direction. The cover has a restricting portion that is in contact with the object while the cover covers the housing chamber. The protrusion engages with the positioning portion when the object is fixed in the body case. The restricting portion restricts a displacement of the object in a direction opposite to the intersecting direction.

Abstract: An electronic control unit includes a control board, a battery pack, and a housing that accommodates the control board and the battery pack. The electronic control unit further includes a battery holder that has a bent shape and includes a bottom surface along a longitudinal direction of the battery pack, the battery holder clamping a main body of the battery pack, and a fixing frame that includes a juxtaposing and mounting part on which a plate surface of the control board and the bottom surface of the battery holder are mounted in a state of being adjacent to each other with a boundary line along the longitudinal direction therebetween, the control board and the battery holder being fixed to the juxtaposing and mounting part. The housing includes an opening portion into which the juxtaposing and mounting part of the fixing frame is inserted, and a back side holding portion that holds the juxtaposing and mounting part at an inner back side of the housing opposed to the opening portion.

Abstract: In a connector device, a side surface of a protruding part on a base portion side of an opposite part is configured as an inclined surface that comes closer to an opposite surface in a direction toward the base portion side of the opposite part, and is engaged with an inclined surface of a second connector in a state where a first connector and the second connector are fitted together. The connector device includes a disengaging member that has a disengaging part arranged between the opposite part of the first connector and the second connector and including an end surface opposed to a side surface of the protruding part on an end side of the opposite part, and an operating part configured integrally with the disengaging part and protruding toward an opposite side of the disengaging part from the second connector. When the end surface is displaced in a direction to make contact with the protruding part, the end surface presses the protruding part.
