Abstract
An electrically-driven compressor including a housing, an electric motor, a compression mechanism, a cover member, a motor drive circuit, and a sealing member is disclosed. The electric motor is accommodated in the housing. The compression mechanism is accommodated in the housing and operated by the electric motor. The cover member is attached to the housing. The housing and the cover member form an accommodation portion including an accommodation space therein. The motor drive circuit is accommodated in the accommodation space and drives the electric motor. The sealing member is arranged between the housing and the cover member to seal the accommodation space. The sealing member includes an elastic seal portion that comes into close contact with the housing and the cover member. A core sustains the shape of the seal portion in conformance with the circumferential edge of the accommodation space. The core is formed so that at least a circumferential edge part of the core is in conformance with the circumferential edge of the accommodation space. The seal portion is formed integrally with the circumferential edge part of the shape sustaining member by depositing rubber material ther…
