A vibrating device includes a dust filter (119) as a dust-screening member shaped like a plate as a whole, a piezoelectric element (120a) forming a vibrating member arranged outside the dust filter and configured to produce, at the dust filter, vibration having a vibrational amplitude perpendicular to a surface of the dust filter, a holder (145) forming a counter member spaced apart from that surface of the dust filter, on which the piezoelectric element is arranged, a pushing member (151) configured to push the dust filter onto the holder, and a seal (150) forming a first support member arranged between the holder and the dust filter, surrounding a center of the dust filter, and configured to support the dust filter when pushed by the pushing member. The seal is pushed with a pressure of 2 N or less when the pushing member pushes the seal. |
