There has been lack of consideration of heat transferred from a semiconductor module to a capacitor via a bus bar module. Heat generated by a semiconductor module 1 is transferred to a bus bar module 3 via a direct-current terminal 1A of the semiconductor module 1. Then, the heat that has been transferred to the bus bar module 3 is transferred to a pressing member 5 by way of an annular conductor 8 and a bolt 5A as shown in fig. 4(B). As the pressing member 5 is in close contact with a second cooler 2B, the heat transferred to the pressing member 5 is subjected to cooling by the second cooler 2B. Meanwhile, the heat transferred to a projection 6A of a housing 6 is further transferred, via the housing 6, to a first cooler 2A so as to be cooled. Accordingly, in a configuration in which a capacitor 4 is connected to the semiconductor module 1 via the bus bar module 3, it is possible to suppress heat from being transferred from the semiconductor module 1 to the capacitor 4.

A first coolant LB is stored in a rotating electric machine accommodation part (41) of the rotating electric machine case (40). The driving unit (30) has a first connection part (70) that electrically connects the rotating electric machine MOT and the power conversion device PDU and a second connection part (60) that electrically connects a sensor provided in the rotating electric machine MOT and the power conversion device PDU. The first connection part (70) and the second connection part (60) are arranged between the rotating electric machine MOT and the power conversion device PDU in the orthogonal direction.
The present invention addresses the problem of shortening axial length while maintaining the necessary thrust and seal properties of a solenoid device. To solve the foregoing problem, a solenoid device 71 is provided with a bobbin 109 onto which a coil 74 is wound, a fixed core 68 that forms a lower-end surface of a housing space that houses the bobbin, a movable core 69 that is disposed opposite an upper-end surface of the fixed core and moves in the axial direction, and a seal section 107 disposed on an outer peripheral surface of the fixed core, wherein: a roughly ring-shaped protruding section 68B, the inner peripheral side of which is high and the outer peripheral side of which is low, is formed on the inner peripheral side of the upper-end surface of the fixed core so as to face an outer peripheral surface of the movable core; and the seal section is disposed at an axial-direction height so as to overlap with the protruding section.
A signal transmission circuit comprising: a circuit board housed inside a case; a connector mounted upon the circuit board and comprising a first signal terminal and a first ground terminal; and an integrated circuit mounted upon the circuit board and comprising a second signal terminal and a second ground terminal. The first signal terminal and the second signal terminal are mutually connected by signal wiring arranged on the circuit board. The first ground terminal and the second ground terminal are mutually connected by ground wiring arranged in a prescribed area of the circuit board that includes the area directly above or directly below the signal wiring. The ground wiring has a high-impedance structure that is formed wider than the signal wiring and narrower than the combined width of the first signal terminal and the first ground terminal, in at least part of the area directly above or directly below the signal wiring.
