The present invention provides a motor that comprises: a housing: a stator that is included in the housing and around which a coil is wound; a rotor coupled to the inside of the stator; a shaft coupled to the rotor; and a bus bar-terminal assembly that includes a bus bar that includes a connection terminal connected with the coil and a terminal connected with an external power supply and a body that includes the bus bar therein such that the connection terminal and the terminal protrude to the outside, wherein the bus bar-terminal assembly includes an alignment guide part provided on the outer circumferential surface of the body in the height direction and slide-coupled with the inner circumferential surface of the housing. Therefore, the present invention provides an advantageous effect of increasing the assembly efficiency of the motor and reducing the number of components thereof by configuring the terminal of the bus bar and the terminal-housing assembly as a single component and an advantageous effect of easily securing the alignment position by providing the alignment guide part on the outer circumferential surface of the bus bar-terminal assembly and installing a slot or rib at the inside of the housing to correspond to the alignment guide part.
