Abstract
A pump is provided with a pump housing, a vibrating portion, a driving portion, and a displacement regulating portion. The pump housing internally has a pump chamber. The vibrating portion is supported against the pump housing in the pump chamber and divides the pump chamber into a first pump chamber and a second pump chamber. The driving portion drives the vibrating portion so as to bend and vibrate the vibrating portion in a predetermined direction. The displacement regulating portion is positioned to prevent displacement of the vibrating portion that results in plastic deformation.
