It is an object of the present invention to provide an air supply apparatus capable
of increasing a height of a scroll lap. The air supply apparatus comprising a stator
fixed to a motor frame, a rotor which is fixed to a motor shaft and rotated in
the stator, a orbiting scroll which is operated by a mechanism shaft, a stationary
scroll for forming a compression space between the stationary scroll itself and
the orbiting scroll, and a rotation-restraint member for turning the orbiting scroll,
in which the motor shaft and the mechanism shaft are connected to each other, the
mechanism shaft passes through the orbiting scroll and the stationary scroll, the
mechanism shaft is held by opposite ends of the orbiting scroll, wherein opposite
ends of the motor shaft are rotatably held by a first bearing and a second bearing,
one end of the mechanism shaft is held by the second bearing.
