PROBLEM TO BE SOLVED: To provide a coolant pump which can suppress an increase of a discharge amount even when the number of revolutions of an internal combustion engine is increased.SOLUTION: A coolant pump comprises a rotor R to which a drive force is transmitted via a clutch mechanism C for connecting and disconnecting the drive force of a rotating body 3 driven by an internal combustion engine E. The clutch mechanism C comprises a contact transmission member 13 which is displaceable in a direction separating from the rotating body 3 accompanied with the rotation of the rotor R by being supported by the rotor R, and an energization member 14 which applies an energization force to the contact transmission member 13 in a direction where the contact transmission member comes into contact with the rotating body 3.SELECTED DRAWING: Figure 1 【課題】内燃機関の回転数が増大した場合でも、吐出量の増大が抑制される冷却液ポンプを構成する。【解決手段】内燃機関Ｅで駆動される回転体３の駆動力を断続するクラッチ機構Ｃを介して駆動力が伝えられるロータＲを備えている。クラッチ機構Ｃが、ロータＲに支持されることでロータＲの回転に伴い回転体３から離間する方向に変位自在な接触伝動部材１３と、この接触伝動部材１３を回転体３に接触する方向に付勢力を作用させる付勢部材１４とを備えて構成されている。【選択図】図１
