The cover part (300) is provided with a transmission part (310) and a heater part (320). At least a portion of the heater unit (320) is disposed on one of both lateral sides of the transmissive unit (310) (the positive direction side in the fifth direction (L)) and on the lower side of the transmissive unit (310) (the negative direction side in the sixth direction (V)). The amount of heat generated per unit length of the heater section (320) in the outer circumferential direction of the transmissive section (310) on the lower side (the negative direction side in the sixth direction (V)) of the transmissive section (310) is higher than the amount of heat generated per unit length of the heater section (320) in the outer circumferential direction of the transmissive section (310) on one of the two lateral sides (the positive direction side in the fifth direction (L)) of the transmissive section (310).
罩部(300)具备透射部(310)及加热器部(320)。加热器部(320)的至少一部分配置于透射部(310)的两横侧的一者(第五方向(L)的正方向侧)和透射部(310)的下侧(第六方向(V)的负方向侧)。于透射部(310)的下侧(第六方向(V)的负方向侧)处的沿透射部(310)外周方向上的加热器部(320)的每单位长度的发热量比于透射部(310)的两横侧的一者(第五方向(L)的正方向侧)处的沿透射部(310)外周方向上的加热器部(320)的每单位长度的发热量高。
