Summary:The present invention relates to a valve operating mechanism for a poppet valve of an internal combustion engine, said mechanism comprising a spring retainer made of light alloy such as Al alloy which is mounted to the poppet valve via steel cotters, thereby increasing load of falling the cotters out of the lower end of the spring retainer. To operate a poppet valve in an internal combustion engine, a valve operating mechanism comprises a valve spring retainer which has a taper bore, a pair of cotters which is inserted in the bore to support the poppet valve, and a valve spring between the valve spring retainer and a cylinder head. There is provided means for preventing the cotters from falling out the bore.
