Title: Motion converting unit

Abstract: The multi-functional motion converting unit can be compact, efficient and inexpensive. In the motion converting unit of the present invention, a holding member is provided in a plane. A swing fin is extended, from the holding member, in a direction perpendicular to the plane. The swing fin has a first face and a second face, which cross a swing direction of the swing fin. The faces are capable of guiding a flow of a fluid.
