Abstract

An optical unit (100) includes a shade (130,140), a motor (150), and a casing (170). The shade (130,140) is movable between an advanced position a retreated position. The motor (150) includes terminal connection parts (153A,153B), and an output shaft (152) connected to the shade (130,140). The motor (150) moves the shade (130,140) from one of the advanced position and the retreated position to the other by rotation of the output shaft (152). The casing (170) includes wall parts (172a,172b,172c,172d,172e), an opening part (176), a connector(178), and power supply terminals (180A,180B). The wall parts (172a,172b,172c,172d,172e) forms an accommodation space. The opening part is used to insert the motor into the accommodation space (174) therethrough. The power supply terminals (180A,180B) are electrically connected to the connector (178) and exposed to the accommodation space (174). The power supply terminals (180A,180B) are disposed in the accommodation space (174) so that the terminal connection parts (153A,153B) and the power supply terminals (180A,180B) are brought into physical contact with each other when the motor (150) is inserted into the accommodation space (174).
