Provided is a head-up display device such that shaking of a display image due to vibration can be mitigated. This head-up display device, which reflects display light output from a display unit with a reflection unit so as to produce an image to be viewed, includes a first supporting part for supporting the reflection unit rotatably about a rotation axis and a first supported part provided at one end of the reflection unit and supported by the first supporting part. The first supported part has a spherical surface formed thereon, and the first supporting part has a sliding surface that is formed therein and is in substantially point contact or line contact with the spherical surface formed on the first supported part. A first elastic member that presses the first supported part and the first supporting part against each other in the rotation axis direction is provided.

Head-up display support structure for reflection unit

A power transmission device which is free from a possibility of breakage of a driving member is provided. A stepping motor (driving member)configured to be driven on the basis of a command signal from a controller, a lead screw portionconfigured to be rotationally driven in association with the drive of the stepping motor, and a power transmitting memberconfigured to move along an axial direction X of the lead screw portionin accordance with the rotation of the lead screw portionand transmit a power to a power transmitted memberare provided, and the controlleris configured to control the output of the command signal to the stepping motorto be stopped when the power transmitting memberis not moved along the axial direction X.

Power transmission device

A method including acting a pointer toward a first target value B of the pointer from an indicated value A of the pointer determined at the present time, comparing the first target value B and a second target value C, judging whether the second target value C is increased or decreased relative to first target value B, using a predetermined function to obtain an indicating characteristic which indicates a value equal to or more than first target value B from the indicated value A of the pointer where the second target value is increased, and an indicating characteristic indicating a value equal to or less than first target value B from indicated value A of the pointer where the second target value is decreased, and smoothly acting the pointer using an indicated value p in unit of output updating cycle in accordance with the indicating characteristics.
