Abstract
A water discharge device that discharges water while reciprocally vibrating the water. The water discharge device includes a water discharge device body and a vibration generating element. The vibration generating element includes a water supply path, a collision portion, a vortex street path, and a discharge path. The vortex street path is formed by fitting an upstream fitting portion of an upstream member and a downstream fitting portion of a downstream member to each other. The upstream member or the downstream member is provided with a vibration reducing portion that reduces vibration of the upstream member due to vortices generated in the vortex street path. The upstream fitting portion or the downstream fitting portion is elastically deformed by a predetermined amount due to the provision of the vibration reducing portion.
