Abstract: A motor-driven compressor includes collars, which maintain the gap between a cover and an outer surface of a first housing member. Fasteners fasten the cover to the first housing member. Each collar is arranged to face a seating surface of the head of the corresponding fastener such that the cover is sandwiched between the collars and the seating surfaces. Each collar thus includes a facing portion, which faces the seating surface and receives a pressing force from the seating surface via the cover, and a transmitting portion, which transmits the pressing force received at the facing portion to a base member. Accordingly, the pressing force applied through the seating surface of the fastener is transmitted to the base member through the collar, so that the base member is pressed against the outer surface of the first housing member.

Abstract: A fluid machine includes a housing, an electric motor, a drive circuit that includes a heat-generating component and drives the electric motor, a cover that defines an accommodation chamber, which accommodates the drive circuit, with the housing, and a fastener that fastens the cover to the housing. The cover is configured to press the heat-generating component or a heat transfer member, to which heat of the heat-generating component is transferred, against the housing in a fastening direction of the fastener when fastened by the fastener. The fluid machine further includes a seal that is held between the first opposing surface of the housing and the second opposing surface of the cover in the direction intersecting the fastening direction of the fastener.

Abstract: An electric compressor includes a cylindrical motor housing, an inverter case, and a conductive member. The inverter case is joined to an end portion of the motor housing. The inverter case includes a cylindrical case peripheral wall surrounding the end portion. The end portion has an end face that extends in a radial direction of the motor housing and a peripheral surface that extends in an axial direction of the motor housing and is connected to the end face. A ring-shaped sealing member is disposed between the peripheral surface and the case peripheral wall. An accommodation groove for accommodating the sealing member is recessed in the peripheral surface. The sealing member is held by the peripheral surface and the case peripheral wall in a radial direction of the sealing member to seal a space in which the conductive member is disposed.

Abstract: An electric compressor includes a housing a compression mechanism, an electric motor and a motor driving circuit. The motor driving circuit includes a circuit board and an electronic component mounted on the circuit board. The electric compressor further includes a bus bar, a shield plate having a bolt hole and an intervening portion interposed between the bus bar and the shield plate. The bus bar, intervening portion and the shield plate are integrated by a resin member. A part of the intervening portion on a side thereof opposite from the shield plate and/or a part of the bus bar on a side thereof opposite from the shield plate is exposed without being covered with the resin member. A surface of the shield plate around the bolt hole on a side thereof opposite from the intervening portion is exposed without being covered with the resin member.
