| description | Provided is a headup display device which is not liable to generate abnormal sound. The headup display device comprises: a liquid crystal display (20) for emitting display light (M); a concave mirror (D1) for reflecting the display light (M); and a motor device (1) for rotating the concave mirror (D1). The motor device (1) includes: a motor (10) having a motor shaft (150) projecting from a motor body (110); a worm (2) connected to the motor shaft (150) and having a spiral groove (21) formed on the outer peripheral surface (20); and a worm wheel (3) provided with teeth (36) engaging with the spiral groove (21) and transmitting a driving force from the motor (10) to the concave mirror (D1). A hole (23) is formed inside the worm (2) extending in the axial direction of the worm (2) from the end face (292) of the worm (2) near the motor body (110). A compression coil spring (8) is arranged in the hole (23) for biasing the worm (2) in the direction opposite the motor body (110) and biasing the motor shaft (150) toward the motor body (110). |
