A projection type image display apparatus for projecting optical fluxes from a light source onto a projection plane so as to display an image, provided with a reflection mirror arranged in such a manner that the reflection mirror interrupts an optical path of the projection light in the direct projection mode when the reflection mode is set and reflects the projection light to the backside of the projection type image display apparatus, and when the reflection mode is set, the projection type image display apparatus is tilted to the backside. The projection type image display apparatus is further provided with an adjustment leg arranged in a front portion of a bottom plane of the projection type image display apparatus and extended by a predetermined leg length, and thereby the projection type image display apparatus is tilted to the backside.
