Cooling device

A cooling device comprising:

• a fan motor including a rotation shaft, an impeller supported by the rotation shaft to rotate integrally with the rotation shaft, and a sleeve bearing unit configured to pivotally support the rotation shaft;
• and
• a heat sink including a plurality of heat radiation pins extending from a base portion,
• wherein the fan motor is placed on the heat sink,
• the impeller includes a blade support element supported by the rotation shaft and a fan blade extending from the blade support element in an outer peripheral direction of the rotation shaft,
• the heat radiation pins extend from the base portion toward the sleeve bearing unit in a direction along the rotation shaft,
• the impeller is spaced apart from the heat radiation pins between the sleeve bearing unit and the heat radiation pins, and
• the blade support element and at least one of the heat radiation pins overlap with each other as viewed in an axial direction of the rotation shaft.
