An air passage (12) and two lines of cleaning liquid paths (11a) and (11b) are provided in a nozzle (7), and furthermore, the air passage (12) is bifurcated into two lines of distal end portions (14a) and (14b). Then, a distal end portion of the cleaning liquid path (11a) and the distal end portion (14a) of the air passage (12) are caused to merge, and a distal end portion of the cleaning liquid path (11b) and the distal end portion (14b) of the air passage (12) are caused to merge. Thus, if the compressed air is supplied to the air passage (12), the resulting air flow causes a negative pressure on the downstream side. This makes it possible to make a cleaning liquid into the form of a mist and suction it, and to mix the cleaning liquid in the form of a mist with the compressed air, whereby it is possible to clean the lens surface (1a) of a camera. Furthermore, by making the cleaning liquid into the form of a mist, it is possible to reduce the amount of the cleaning liquid used.
