A projection apparatus for a vehicle of the present invention includes a projector for projecting an image onto a screen, a support bracket supporting the projector, a frame attached to a ceiling of the vehicle, and a vibration absorber arranged between the support bracket and the frame. The vibration absorber includes a plurality of wire ropes for absorbing multidirectional vibrations transmitted from the vehicle through the frame to the projector. Accordingly, this prevents the projector from shaking so that passengers can comfortably watch video content, and also reduces the incidence of breakage of components of the projector, thereby prolonging the lifetime of the projector.
