Variable valve timing device

摘要

A variable valve timing control device includes a rotation member unitary fixed to a rotation shaft for controlling a valve timing assembled to a cylinder head of an internal combustion engine to be rotatable, a rotation transmission member engaged with the rotation member to be relatively rotatable, a vane provided on either one of the rotation member or the rotation transmission member, a hydraulic pressure chamber formed between the rotation member and the rotation transmission member and is divided into an advance angle chamber and a retarded angle chamber by the vane, and a detection member for detecting a relative rotation phase between the rotation member and a crankshaft. The detection member is press fitted into a cylindrical portion formed in an axial direction of the rotation member and the rotation member is fixed to the rotation member by a tightening member.
