Electric motor for vehicle

An electric motor for vehicle comprising:

• a stator around which coil is wound;
• a stator support member configured to support the stator;
• a rotation shaft rotatably supported by the stator support member via an axle bearing and extends in a horizontal direction;
• a rotor including a bottom wall of a disc-like shape that covers one side of the stator in an axial line direction of the rotation shaft and a peripheral wall of a cylinder-like shape that rises from an outer circumferential end of the bottom wall and covers an outer circumferential side of the stator, in which the peripheral wall is provided with a magnet and the bottom wall is configured to be integrally-rotatably combined with the rotation shaft;
• and
• a bearing holder including a tube part of a cylinder-like shape configured to support the axle bearing in an inner circumferential side thereof, and a water drip hole is formed in a vertically lower side of the tube part, the stator support member being provided with a bearing holder insertion part including a boss part of a cylinder-like shape into which the tube part is configured to be inserted,
• wherein a water drain structure configured to drain a water drop from the water drip hole toward outside is provided along a circumferential direction of an inner circumferential surface of the boss part in a vertically lower area of the inner circumferential surface of the boss part, and
• the water drain structure is a plurality of concave parts recessed from the inner circumferential surface of the boss part toward outside in a radial direction and are communicated to an outside of the boss part.
