To provide an optical scanner that can prevent a trouble caused by deformation of an attachment part due to a change in temperature, the attachment part attaching an optical member to a housing, an image projection device, and a movable body.SOLUTION: An optical scanner comprises: a light source 111; scanning means that deflects light from the light source 111 in a main scanning direction α to scan an area to be scanned; an optical member 112 that guides the light from the light source 111 to the scanning means; a housing 240 that holds the light source 111 and optical member 112; and an attachment part 250 that attaches part of the optical member 112 to be bridged over the housing 240. The direction of bridging is adjusted to a direction α corresponding to the main scanning direction of the scanning means.SELECTED DRAWING: Figure 1
【課題】光学部材を筐体に対して取り付ける取付部が、温度変化によって変形することに起因する不具合を抑制できる光走査装置、画像投写装置及び移動体を提供する。【解決手段】光源111と、光源111からの光を主走査方向αへ偏向して被走査領域を走査する走査手段と、光源111からの光を走査手段に案内する光学部材112と、光源111及び光学部材112を保持する筐体240と、筐体240に対して光学部材112の一部を架橋して取り付ける取付部250とを備える光走査装置において、前記架橋の方向を、走査手段の主走査方向に対応する方向αに合わせる構成とする。【選択図】図1
