To provide a projection device that, even when the shape of a housing is changed, can standardize the positional relationship between an image forming unit and an imaging optical system, and a movable body.SOLUTION: A projection device comprises: an image forming unit that makes incident radiation light radiated from a light source, forms an image, and emits image light; an imaging optical system 30 that reflects the image light to form an image; and a housing 102 that accommodates the image forming unit and the imaging optical system 30 and transmits the image light reflected by the imaging optical system 30. The projection device comprises a positioning member 1030 that positions and holds the image forming unit and the imaging optical system 30 and is attached to the housing.SELECTED DRAWING: Figure 18
【課題】筐体の形状を変更した場合でも、画像形成部と結像光学系の位置関係を共通化できる投射装置および移動体を提供する。【解決手段】光源から照射される照射光を入射して、画像を形成し、画像光を出射する画像形成部と、前記画像光を反射して像を結像させる結像光学系30と、前記画像形成部および前記結像光学系30を収納するとともに、前記結像光学系30により反射された前記画像光を透過させる筐体102と、を備えた投射装置であって、前記画像形成部および前記結像光学系30をそれぞれ位置決めして保持して、前記筐体に対して取り付けられる位置決め部材1030を備える。【選択図】図18
