Abstract
Inclination of an image display unit is prevented at the time of using a wearable display unit in which the image display unit can move between a projection position where the image display unit comes in front of a user's eye and a retracted position where the image display unit has been retracted from the front of the user's eye. A display support memberis prevented from rotating in relation to a display support member housing partin a direction included in a plane perpendicular to the longitudinal direction of the display support member, even in a state that the display support member can move. To that end, groovesextending in the longitudinal direction are formed in the display support member, while guide rollersin contact with these grooves are provided within the display support member housing part
