Abstract: Disclosed is an all-solid-state battery capable of suppressing volume expansion during charging and discharging.

Abstract: This embodiment relates to a motor comprising: a housing; a stator disposed within the housing; a rotor disposed inside the stator; and a shaft coupled to the rotor. The housing includes a body and a plurality of protrusions that protrude inward from the inner circumferential surface of the body, and the stator includes a stator core and a coil wound on the stator core. The inner surfaces, which are the inside surfaces of the protrusions, are in contact with the outer circumferential surface of the stator core, and the protrusions are disposed spaced apart at predetermined intervals along the circumferential direction such that gaps (G) are formed in the radial direction between the outer circumferential surface of the stator core and the inner circumferential surface of the body. Accordingly, the protrusions formed on the housing of the motor reduce the amount of contact between the housing and the stator core, and can thus improve friction torque performance.
