Motor and blower

A motor comprising:

• a shaft which extends along a rotation axis extending in a vertical direction;
• a rotor magnet configured to rotate together with the shaft;
• a stator located radially outside of the rotor magnet;
• a housing including a housing tubular portion which extends along the rotation axis;
• a cap located at an axially upper end portion of the housing;
• and
• a bearing portion configured to rotatably support the shaft, and supported by at least one of the housing and the cap;
• wherein
• the stator includes a stator core including an annular core back and a plurality of teeth which project radially inward from the core back;
• the core back includes a tubular outer circumferential surface, the outer circumferential surface including a plurality of stator contact portions each of which is in contact with the housing tubular portion;
• the stator contact portions are spaced from one another in a circumferential direction;
• the cap includes:
• a cap bottom portion perpendicular or substantially perpendicular to the rotation axis;
• and
• a cap tubular portion extending axially downward from the cap bottom portion;
• the cap tubular portion includes a plurality of cap contact portions each of which is in contact with the housing;
• the cap contact portions are spaced from one another in the circumferential direction;
• and
• at least one of the cap contact portions is located at a circumferential position different from a circumferential position of each of the stator contact portions.
