Claims

[Scope of utility model registration request]

A driven-side rocker arm 5 is interlocked and connected to a valve-driving cam 2 of a valve-driving device 1 of an engine E via a driving-side rocker arm 3 and a clutch 4, and the clutch 4 is configured to be able to be turned on and off by a hydraulic cylinder 6 and a coiled return spring 100. , in a partial valve operation deactivation device of an engine valve train in which the main same side rocker arm 3 and the driven side rocker arm 5 are fitted onto a common rocker arm shaft 7, a coiled return spring 100 is disposed on the rocker arm shaft 7. The spring wire tip portion 105 of the fixed side end portion 104 of the coiled return spring 100 and the spring wire tip portion 1 of the movable side end portion 110 are attached in a fitted manner.
11 are oriented to face each other along the expansion/contraction direction S of the coiled return spring 100, and the fixed side spring wire tip portion 105 is fixed to the spring receiving portion 102 that does not move relative to the rocker arm shaft 7 in the axial direction and rotational direction. The movable spring wire tip 111 is connected to the output end 36 of the driven rocker arm 5 so that the coiled return spring 10 presses the driven rocker arm 5 in the clutch 4 release direction and valve opening direction. A partial valve train deactivation device for a valve train of an engine, characterized in that the device is engaged with a valve train of an engine.
