(57) Abstract :
A motor-driven compressor that suppresses the transmission of vibration and noise to the exterior, while obtaining heating
performance that is sufficient for use in a heat pump. The motor-driven compressor includes a compressor mechanism, which
compresses a refrigerant, and a motor mechanism, which actuates the compressor mechanism. The motor-driven compressor
further includes an inner housing, which accommodates the compressor mechanism and the motor mechanism in a sealed state,
and an outer housing, which accommodates the inner housing. The outer housing includes a mounting portion that can be mounted
to another member. A first intermediate member is arranged between the inner housing and the outer housing. The first
intermediate member includes anti-vibration and thermal insulation properties.
