Abstract
A compressor includes a crankshaft, an electric motor, a counterweight, and an oil outflow reduction member. The electric motor has a rotor coupled to the crankshaft and a stator in which the rotor is housed with an air gap formed between the stator and the rotor. The counterweight is disposed adjacent to the rotor and is integrated with the crankshaft. The oil outflow reduction member encloses an upper side, a lower side, and a lateral side of a counterweight passing space. The counterweight passing space is a space through which at least part of the counterweight passes when the crankshaft rotates 360°.
