the support pillar is disposed closer to a rear end of the support unit than a front end of the support unit.

10. A blower comprising:

a blower unit that has a housing defining a slit therein which extends vertically;

a support unit that has a support pillar inserted through the slit of the housing and pivotally coupled with the blower unit to make the blower unit swingable vertically; and

a pivotally coupling mechanism that is configured to restrict release of a pivotally coupled state of the blower unit and the support pillar,

wherein the pivotally coupling mechanism has a lock portion protruding from the blower unit in a direction of a swing axis thereof, a flange along an end edge of the lock portion, a slit that is on the support pillar and in which the flange is movably inserted, and a protrusion provided in the slit of the support pillar, and

wherein the support pillar is restricted from being pulled out from an axial portion of the blower unit by rotating the support pillar such that the protrusion and the flange are facing each other in the direction of the swing axis.

11. The blower according to claim 10 , wherein

the housing has a front cover and a rear cover that are dividable at a center of the blower unit, and
