PROBLEM TO BE SOLVED: To provide a vehicle oil pump drive device capable of improving fuel consumption by reducing the friction due to the drive of an oil pump.SOLUTION: A vehicle oil pump drive device having oil pump driven accompanying the rotation of an engine output shaft, comprises: a first torque transmission mechanism that connects the output shaft of an engine to the drive shaft of the oil pump with a first change gear ratio; and a second torque transmission mechanism that connects the output shaft of an engine to the drive shaft of the oil pump with a second change gear ratio which is different from the first change gear ratio. The first torque transmission mechanism includes a first clutch; and the second torque transmission mechanism includes a second clutch. At least one of the first clutch and the second clutch is a clutch for switching transmission or interception of torque by an axial load produced by the torque input to a helical gear.SELECTED DRAWING: Figure 1

    【課題】オイルポンプの駆動によるフリクションを低減して燃費を向上可能な車両のオイルポンプ駆動装置を提供する。【解決手段】エンジンの出力軸の回転に伴って駆動するオイルポンプを備えた車両のオイルポンプ駆動装置において、エンジンの出力軸とオイルポンプの駆動軸とを第1の変速比で連結する第1のトルク伝達機構と、エンジンの出力軸とオイルポンプの駆動軸とを第1の変速比とは異なる第2の変速比で連結する第2のトルク伝達機構と、を備え、第1のトルク伝達機構は第1のクラッチを有し、第2のトルク伝達機構は第2のクラッチを有し、第1のクラッチ及び第2のクラッチの少なくとも一方は、ヘリカルギヤへのトルク入力により生じる軸方向荷重によってトルクの伝達又は遮断を切り替えるクラッチである。【選択図】図1
