차량용 촬영 장치는, 창부(85)의 광속 투과부(85a)를 투과한 촬영 광속을 수광하도록 구성되는 촬영 소자(30)와, 전열선에 의해 구성된 히터(47A, 47B)와, 상기 광속 투과부(85a)의 내면과 대향하고, 또한 상기 히터(47A, 47B)가 고정된 피가열부(40A, 40B, 40C, 40D)와, 상기 히터(47A, 47B)에의 통전 상태를 전환하도록 구성된 스위치 소자(89)와, 상기 피가열부(40A, 40B, 40C, 40D)에 배치된, 전류 제한 소자(52, 91)를 구비하고, 상기 전류 제한 소자(52, 91)는, 전력이 상기 스위치 소자(89)를 회피하면서 상기 히터에 공급되도록 상기 전기 회로에 쇼트가 발생하여, 상기 전류 제한 소자(52, 91)의 온도가 소정값 이상으로 되었을 때, 상기 히터(47A, 47B)에 흐르는 전류를 제로로 하거나 혹은 감소시키도록 구성된다.

    A photographing device for a vehicle includes: an imaging element (30) configured to receive a photographing beam passing through a beam transmission section (85a) of a window section (85); a heater (47A, 47B) constituted by a heating wire; a section to be heated (40A, 40B, 40C, 40D) to which the heater (47A, 47B) is fixed, the section to be heated (40A, 40B, 40C, 40D) being opposite to an inner side surface of the beam transmission section (85a); a switch element (89) configured to switch electrical connection state to the heater (47A, 47B); and a current limiting element (52, 91) disposed at the section to be heated (40A, 40B, 40C, 40D) and being configured such that current flowing through the heater (47A, 47B) becomes zero or is reduced when the electric circuit is short-circuited such that power is supplied to the heater while bypassing the switch element (89) and a temperature of the current limiting element (52, 91) become equal to or higher than a predetermined value.
