Abstract
Notched portions and positioning projecting portions are elastically engaged with each other to hold a fan unit at a fixing position in a housing, in a state in which the fan unit is placed at the fixing position.
Claims7
A fan unit fixing structure comprising:
- a fan unit having a fan device for rotating a fan, and an elastic holder for holding the fan device;
- piece portions provided at positions at which the fan unit placed at a fixing position in a housing is sandwiched between the piece portions from both sides thereof;
- first elastic engagement portions provided in an outer peripheral portion of the holder, the first elastic engagement portions corresponding to the piece portions;
- second elastic engagement portions provided in the piece portions, and elastically engaged with the first elastic engagement portions in a state in which the fan unit is placed at the fixing position, to hold the fan unit at the fixing position;
- a drawn portion provided so as to project toward an inside of the housing, serving as a base of the fan unit placed at the fixing position, and having a seat surface in which a hole is formed;
- a second projecting portion provided so as to project from the outer peripheral portion of the holder, and fitted into the hole in a state in which the fan unit is placed at the fixing position;
- a contact portion provided so as to project from the outer peripheral portion on a periphery of the holder which is opposite to the second projecting portion;
- and
- a hitting portion provided so as to project from a top plate, and being in contact with the contact portion while applying pressure to the contact portion, in a state in which the top plate is mounted to the housing.
