A fixing structure for an electrical component includes a heat removing member for removing heat from the electrical component. The heat removing member has a receiving portion for receiving the electrical component. The fixing structure for an electrical component further includes a separation member that is coupled to the electrical component to separate the electrical component from the heat removing member. The separation member is coupled to the heat removing member. The fixing structure for an electrical component includes a soft material member that is accommodated in the receiving portion to contact the receiving portion and the electrical component. Heat of the electrical component is transmitted to the heat removing member via the soft material member.

A motor-driven compressor includes a housing having at one end thereof an accommodation space, an electric motor, a motor driver circuit provided in the accommodation space and having a circuit board, a connector having a bus bar electrically connected to the circuit board, and a cylindrical portion located at the one end of the housing and extending toward the direction close to the electric motor. The housing has a mounting hole communicating with the accommodation space and the interior of the cylindrical portion. The bus bar has a bent shape having opposite ends extended toward the direction close to the electric motor. The connector is disposed in the mounting hole with one end of the bus bar inserted in the cylindrical portion and the other end of the bus bar inserted in the accommodation space. The mounting hole is closed up by a cover with a seal member provided therebetween.

An electric compressor includes a compression mechanism, an electric motor for driving the compression mechanism, and a drive circuit for controlling the electric motor. The drive circuit includes an external connector made of an insulating material. The external connector has a connecting terminal that is constructed to be electrically connected to an external power source. The drive circuit further includes a circuit board electrically connected to the connecting terminal and a filter element electrically connected to the circuit board. The drive circuit is accommodated in a metal housing. The filter element is integrally formed with the external connector such that contact of the filter element with the housing is prevented.

An electric compressor includes an inverter cover. The inverter cover has a metal plate that is arranged to cover an inverter (a circuit board). The metal plate has bolt insertion holes, through which metal bolts for fixing the inverter cover to a suction housing are passed. The head of each bolt contacts a flange portion, which is the periphery of the corresponding bolt insertion hole. The inverter cover is formed of plastic by being molded in a mold, using the metal plate as a core.

A structure for connecting a circuit board and an external connector includes a lead and a stress dampening unit. The lead electrically connects the circuit board and the external connector. The external connector is fitted to and removed from the lead. The stress dampening unit dampens stress applied to the circuit board by the lead when the external connector is fitted to and removed from the lead.

A running control device of a vehicle includes an engine, a connecting/disconnecting device separating the engine and wheels, and a transmission transmitting power of the engine toward the wheels, the running control device being configured to execute a normal running-mode performed by using the power of the engine with the engine and the wheels coupled, a free-run inertia running-mode that is performed by separating the engine and the wheels and stopping the engine during running, and a neutral inertia running-mode that is a performed by separating the engine and the wheels and operating the engine in a self-sustaining manner during running, the running control device setting a gear ratio of the transmission on a low vehicle speed side in the case of return from the free-run inertia running-mode to the normal running-mode as compared to the case of return from the neutral inertia running-mode to the normal running-mode.

A running control device of a vehicle includes an engine and a brake booster amplifying a brake force by forming a negative pressure in a negative pressure tank by rotation of the engine. The running control device is configured to execute an engine brake running mode performed with the engine coupled to wheels such that an engine brake is applied by driven rotation of the engine and an inertia running mode performed with an engine brake force made lower than that of the engine brake running mode. The running control device executes a first inertia running mode performed with the rotation of the engine stopped and a second inertia running mode performed with the engine kept rotating as the inertia running mode in accordance with predefined respective execution conditions. The running control device comprises a prediction portion configured to predict a necessity of the negative pressure.
