カムと、該カムを流体圧により軸方向に移動させるアク
チュエータと、カムの回転に同期されており前記カムが
すべてベース径部においてロッカアームに臨む位置にあ
るときにのみ前記アクチュエータに流体圧を供給する流
体圧供給装置とを備えた可変バルブタイミング装置。A cam with a plurality of cam ridges on the same shaft that act on an on-off valve, an actuator that moves the cam in the axial direction using fluid pressure, and a cam that is synchronized with the rotation of the cam so that all of the cams are located at the base diameter part. A variable valve timing device comprising: a fluid pressure supply device that supplies fluid pressure to the actuator only when the actuator is in a position facing the rocker arm.
