PROBLEM TO BE SOLVED: To prevent an operation member from interfering with an end face cam of a cam element part due to operation failure by spontaneously and continuously switching a cam while securing mountability to an engine in a valve gear of an engine in which a cam for opening/closing a valve can be switched.SOLUTION: A cam element part comprises: a slope part for forcedly moving an operation member to a non-actuation position after movement by an end face cam is completed by slide-contacting a contact part provided on the operation member while the operation member is at an actuation position; and a restraining part for restraining inrush of the operation member formed continuously with the slope part. The slope part and the restraining part are provided at least corresponding to a non-actuation range of the end face cam. |
