A motor-driven compressor in which an electric driving mechanism is capable of keeping high efficiency. The compressor includes an electric driving mechanism, a compression mechanism and a motor drive circuit. The electric driving mechanism is accommodated in a housing. The housing has a main body portion in a cylindrical shape, a bulging portion that bulges in a radially outward direction from the main body portion, and a partition wall. In the main body portion, a stator accommodation chamber is formed. In the stator accommodation chamber, a stator of the electric driving mechanism is accommodated. In the bulging portion, a cluster block accommodation chamber is formed. In the cluster block accommodation chamber, a cluster block is accommodated. A partition wall separates the stator accommodation chamber and the cluster block accommodation chamber in a radial direction. The main body portion and the partition wall support a stator core. |

1. A motor-driven compressor comprising an electric driving mechanism, a compression mechanism that is driven by the electric driving mechanism, and performs compression of a refrigerant, and a motor drive circuit for driving the electric driving mechanism,
wherein the electric driving mechanism has a stator that is accommodated in a housing, and has a stator core and a coil provided at the stator core, a rotor rotatably provided in the stator, a drive shaft that is fixed to the rotor and drives the compression mechanism, a lead wire connected to the coil, and a cluster block for electrically connecting the lead wire to the motor drive circuit, the housing has a main body portion in a cylindrical shape that forms a stator accommodation chamber in which the stator is accommodated in an inside thereof, a bulging portion that bulges in a radially outward direction from the main body portion, and forms a cluster block accommodation chamber in which the cluster block is accommodated in an inside thereof, and a partition wall that separates the stator accommodation chamber and the cluster block accommodation chamber in a radial direction, and the housing supports the stator core at the main body portion and the partition wall, and has the lead wire disposed across the stator accommodation chamber and the cluster block accommodation chamber. |
