A stator (110) includes a stator body and a plurality of compression beads formed on an outer surface of the stator body (111 ) to reduce a contact surface between the stator body (111 ) and an inner surface of the shell (120), the plurality of compression beads (112) being compressed by the inner surface of the shell (120) and thus held therein when the stator (110) is fitted into the shell (120). Further, the plurality of compression beads (112) is oriented in a direction in which the stator body (111 ) is fitted into the shell (120), and each of the plurality of compression beads (112) has an inclined guide part (113) on an end corresponding to an end of the stator body (111 ) that is first fitted into the shell (120), to guide the fitting of the stator body (111 ).
