Abstract: A cleaning device for an imaging unit includes a housing that holds an imaging section, a protection cover provided in the visual field of the imaging section, a vibrator section that vibrates the protection cover, and a cleaning nozzle that discharges a cleaning liquid. The cleaning liquid discharged by the discharge section reaches a surface of side of the protection cover that is opposite to the side thereof adjacent to or in a vicinity of the imaging section. According to the vibrator section vibrating the protection cover, a portion of surface of the protection cover exhibits an amount of displacement larger than that of a portion of surface of the protection cover that the discharged cleaning liquid has reached.

Abstract: A vibrating device includes a tubular body including first and second end surfaces, and a side wall portion that connects the first and second end surfaces, a piezoelectric vibrator provided on the first end surface of the tubular body, and a light transmitting body that is directly or indirectly connected to the second end surface and covers an opening in the second end surface of the tubular body. A connecting portion is connected to the first end surface of the tubular body inside or outside an opening in the first end surface. A tubular bent portion is connected to a surface of the connecting portion that faces toward the second end surface of the tubular body. The tubular bent portion extends in a direction from the first end surface toward the second end surface of the tubular body.
