PROBLEM TO BE SOLVED: To provide an image projection device that suppresses a cover member from having a high temperature even if a light source has the high temperature in a light source unit having a light source and cover member integrally configured.SOLUTION: In an image projection device comprising a light source unit 50 that is configured to be attachable/detachable to/from a device main body via an attachment/detachment port 18a of the device main body, and projecting an image using light of a light source 51 in the light source unit 50, a cover member 52 of the attachment/detachment port 18a is integrally structured with the light source 51 in a state relatively displaceable relative to the light source 51. A connection portion connectable directly or via a member between the light source 51 and a cover member 18 in an attachment state having the light source unit 50 attached to the device main body is configured so as to be only a connection portion connectable directly or via the member when the light source 51 and the cover member 18 relatively displace in a non-attachment state where the light source unit 50 is not attached to the device main body.SELECTED DRAWING: Figure 6 【課題】光源とカバー部材とを一体構造とした光源ユニットにおいて、光源が使用中に高温になってもカバー部材が高温になるのを抑制する画像投射装置を提供する。【解決手段】装置本体の着脱口１８ａを介して装置本体に対して着脱可能に構成された光源ユニット５０を備え、光源ユニット５０内の光源５１からの光を用いて画像を投射する画像投射装置において、着脱口１８ａのカバー部材５２は、光源５１に対して相対的に変位可能な状態で、光源５１と一体構造になっており、光源ユニット５０が装置本体に対して装着された装着状態において光源５１とカバー部材１８との間で直接又は部材を介して連結し得る連結部位が、光源ユニット５０が装置本体に対して装着されていない非装着状態において光源５１とカバー部材１８とが相対的に変位するときに直接又は部材を介して連結し得る連結部位のみとなるように構成されている。【選択図】図６
