Abstract (en)
To provide a variable phaser for an automobile engine including a self-locking mechanism which does not hinder an operation of changing a relative phase angle of a cam shaft with respect to a drive rotating member. In a variable phaser for an automobile engine including a drive rotating member having a cylindrical section and driven by a crank shaft, a cam shaft coaxially supporting the drive rotating member in a coaxial and relatively rotating fashion, a relative phase angle changing mechanism, and a self-locking mechanism preventing the misalignment of the relative phase angle due to the cam torque by means of pressing the lock plate held on a holding section integral with the cam shaft to an inner circumferential surface of the cylindrical section, plate-pressing surfaces disposed at a plurality of positions almost equally separated along an outer circumferential direction of an outer circumference of the holding section, and a plurality of lock plates equally separated in correspondence to the plate-pressing surfaces are formed, and the respective plate-pressing surfaces are formed by first and second pressing surfaces for delivering the cam torques along advance and lag directions to the respective lock plates.
