Title: VIBRATION DEVICE, WATER DROPLET REMOVAL DEVICE FOR CAMERA, AND CAMERA
Abstract:
Provided is a vibration device in which a piezoelectric vibrator is not subjected to a large load. A vibration device 10, equipped with: a cylindrical body 11 having a first end surface 11a and a second end surface 11b on the opposite side from the first end surface 11a, the cylindrical body 11 having a side wall part 11c connecting the first and second end surfaces 11a, 11b; piezoelectric vibrators 12 provided to the first end surface 11a of the cylindrical body 11; and a translucent part 17 directly or indirectly linked to the second end surface 11b, the translucent part 17 being provided so as to cover an opening in the second end surface 11b of the cylindrical body 11. The vibration device 10 is provided with: a linking part, which is continuous from the inside or the outside of an opening in the first end surface 11a of the cylindrical body, and a cylindrical foldback part 13, which is continuous from the surface of the linking part on the side of the second end surface 11b of the cylindrical body 11 and which extends in the direction from the side of the first end surface 11a towards the side of the second end surface 11b of the cylindrical body 11.
