カム軸と、このカム軸に相対回転変位可能に設け
られ、回転駆動源に連動して回転する回転体と、
上記カム軸を回転体に対して回転方向に沿つて付
勢するばねとを備え、上記回転体とカム軸の回転
角度位置を変化させて上記吸排気弁の開閉タイミ
ングを変化させる可変バルブタイミング装置にお
いて、上記ばねの一端に係合するフロートを設け
、このフロートの上記ばねとは反対側に圧力室を

る可変バルブタイミング装置。 a camshaft provided with a cam for opening and closing the intake and exhaust valves; a rotating body that is rotatably displaceable relative to the camshaft and rotates in conjunction with a rotational drive source;
a spring that biases the camshaft relative to a rotating body along the rotational direction, and a variable valve timing device that changes the opening/closing timing of the intake and exhaust valves by changing the rotational angular position of the rotating body and the camshaft. A float is provided that engages one end of the spring, a pressure chamber is formed on the opposite side of the float from the spring, and a fluid pressure that changes depending on the operating state of the engine is introduced into the pressure chamber. Features a variable valve timing device.
