ABSTRACT:
In a direction display device which indicates direction by an arrow, a translucent direction display portion is formed on an outside housing. A rotation roller is disposed within the housing to be rotated by a motor. Inclined stripes are formed on the rotation roller, and therefore, by the drive force of the motor, the rotation roller rotates in the housing. As a result, the inclined stripes on the rotation roller move in the direction display portion of the housing as if the stripes move in the same direction as the arrow direction. By indicating a direction by the arrow of the direction display portion and the direction of a movement direction of the inclined stripes of the rotation roller, visibility of the indicated direction is increased. In the case that the display device has two arrow portions, the arrow portions to be used is reversed from one to the other and the direction of movement of the inclined stripes is reversed also.
