Beschreibung
Zusammenfassung:	A water pump for a vehicle includes a power transmission member driven and rotated by an external power, a driven shaft driven to be rotatable independently from the power transmission member, an impeller, an arm member which includes a pressing portion pressing the power transmission member and which is contactable to the power transmission member for transmitting a rotation of the power transmission member to the driven shaft, a control member controlling the arm member so that the arm member and the power transmission member come in contact with each other or come out of contact from each other and so that a contact state between the arm member and the power transmission member is variable, and a biasing member biasing the arm member toward the power transmission member.
