【発明が解決しようとする課題】従来の後方監視カメラ
は車体後部に取付けるのが一般的であり、その後方監視
カメラのレンズ部は常時露出しているタイプと、レンズ
部前面に可動式のカバーを備えカメラ作動時のみカバー
を開放するタイプがある。The conventional rear monitoring camera is generally mounted on the rear of the vehicle body. The rear monitoring camera has a lens portion that is always exposed and a movable cover on the front surface of the lens portion. There is a type that has a cover that opens only when the camera is operating.

を走行することが多く、オフロードを走行する際に車体
後方ははね上げによる泥の付着が著しく、後方監視カメ
ラにも泥が多量に付着するという事態が多々発生する。When the above-mentioned rear monitoring camera is mounted on a dump truck for construction equipment, the dump truck for construction equipment is mounted on an unpaved road (ie, off-road) at a civil engineering work site or the like.
When traveling off-road, the rear of the vehicle body is often splashed with mud, and a large amount of mud also adheres to the rear monitoring camera.

状況を確認できず、障害物、人等の検知ができずに非常
に危険である。If mud adheres to the lens portion of the rear monitoring camera, the situation behind the vehicle body cannot be sufficiently photographed. If mud adheres significantly to the lens portion, no photographing can be performed at all. The situation at the rear of the vehicle body cannot be confirmed, and obstacles and people cannot be detected, which is extremely dangerous.

部を清掃することが困難である。Further, as disclosed in Japanese Patent Application Laid-Open No. 59-199343, a surveillance camera has been proposed in which a lens portion can be cleaned with a wiper. However, splashed mud adheres to the lens portion and hardens. The wiper cannot remove the hardened mud and clean it. In particular, since the dump truck for construction equipment has a large splash of mud, it is difficult to clean the lens unit with a wiper.
