Blower device

A blower device comprising:

• a fixing member attached to an outer periphery of a blower case and configured to fix the blower device at a mounting target, wherein
• an outer peripheral surface of the blower case includes:
• a pair of rail parts extending in a direction of a rotation axis of an impeller, and
• an engagement rib bridged at a middle of the pair of rail parts at an intermediate portion of each of the pair of rail parts in a longitudinal direction, and an inclined rib having a triangular shape and including an inclined surface having an ascending gradient toward an upper side in an axial direction is formed at a central portion of the engagement rib, wherein the fixing member includes:
• a pair of fitting parts configured to be fitted with the pair of rail parts and slidable in the direction of the rotation axis, and
• a claw part disposed between the pair of fitting parts and configured to be engaged with the engagement rib in the direction of the rotation axis,
• wherein the pair of rail parts include a plurality of pairs of rail parts disposed along the outer periphery of the blower case, and
• wherein the fixing member is selectively attachable at the pair of rail parts,
• wherein the blower case comprises a blower upper case and a blower lower case, the blower case includes a sidewall, a lower wall, and a curved wall configured to connect the sidewall and the lower wall,
• wherein a gap is provided between a boundary between the curved wall and the sidewall and lower ends of the rail parts in the axial direction, and
• wherein the gap comprises a surface that extends along the sidewall in a circumferential direction about the rotation axis,
• wherein the fixing member includes a first fixing mounting leg projecting to one end side in a direction of the rotation axis, second fixing mounting leg projecting from an end portion of the first fixing mounting leg to another end side in the direction of the rotation axis, and
• an engaging part projecting from an intermediate portion between the first and second
• mounting legs in a circumferential direction about the rotation axis, and
• the pair of fitting parts are disposed at the engaging part.
