PROBLEM TO BE SOLVED: To provide an injection nozzle member securing sealability when injecting compressed air, and surely preventing water droplet and dust from approaching an air injection part side.SOLUTION: An injection nozzle member 10 installed an on-vehicle camera 12 is formed of an elastic material, and has an air passage 28 to which compressed air is supplied, in the inside of a cover part 22 installed on a top face 14b of a housing 14. In an air injection part 26 to which compressed air is injected, a pair of seal portions 36a, 36b are formed in the width direction outside of the air passage 28, and the seal portions 36a, 36b are formed in a lip-like shape projecting downward and toward a width direction center to be the air passage 28 side. The injection nozzle member 10 is abutted so as to bring the tips of the seal portions 36a, 36b to the air passage 28 side when being installed on the on-vehicle camera 12, and is pressed to the housing 14 side by compressed air flowing in the air passage 28 so as to adhere closely.SELECTED DRAWING: Figure 4

    【課題】噴射用ノズル部材において、圧縮エアを噴射する際のシール性を確保しエア噴射部側への水滴や塵埃等の進入を確実に防止する。【解決手段】車載用カメラ12に装着される噴射用ノズル部材10は、弾性材料から形成され、筐体14の上面14bに装着されるカバー部22の内部に圧縮エアの供給されるエア通路28を有する。圧縮エアの噴射されるエア噴射部26には、エア通路28の幅方向外側に一対のシール部36a、36bが形成され、シール部36a、36bは、下方、且つ、エア通路28側となる幅方向中央に向かって突出したリップ状に形成される。そして、噴射用ノズル部材10が車載用カメラ12に装着された際、シール部36a、36bの先端が互いにエア通路28側となるように当接し、前記エア通路28内を流れる圧縮エアによって前記筐体14側へと押圧されることで密着する。【選択図】図4
