According to the present invention, a DC motor for a vehicle includes a yoke (10), a bracket (11) coupled to an upper portion of the yoke (10), and a base (31) coupled to a lower portion of the yoke (10). The DC motor further comprises a magnet holder (16) holding a plurality of magnets (15) coupled to the inner surface of the yoke (10). The magnet holder (16) includes: a central connection portion (161); a fixing protrusion (162) protruding radially outward from an upper portion of the central connection portion (161); a first magnet inner support portion (163) and a second magnet inner support portion (164) respectively extending downward from both sides of the central connection portion (161) in the circumferential direction; and a flow gap (165) located below the central connection portion (161) as a space between the first magnet inner support portion (163) and the second magnet inner support portion (164). According to the present invention, the assembly of the magnets is facilitated, thereby improving the assembling property.
