Fan and indoor equipment

A fan comprising:

• a multi wing fan;
• and
• a mechanism configured to rotate the multi wing fan around a rotation axis,
• wherein the multi wing fan includes
• a plurality of impellers that are lined in an axial direction that is parallel to the rotation axis;
• and
• a partition plate that is arranged along a plane that is perpendicular to the rotation axis,
• the partition plate includes
• a body part that separates two impellers among the plurality of impellers;
• and
• an outer circumferential part that surrounds an outer circumferential side of the body part that is perpendicular to the rotation axis,
• the outer circumferential part is sharp such that the outer circumferential part gets thinner toward an outer circumferential edge of the partition plate,
• the outer circumferential edge of the partition plate is formed of a plurality of outer circumferential edge parts that are continuous in a circumferential direction, and
• a first position of a first outer circumferential edge part among the plurality of outer circumferential edge parts in the axial direction is different from a second position of a second outer circumferential edge part different from the first outer circumferential edge part among the plurality of outer circumferential edge parts in the axial direction.
