The invention discloses a mounting structure for a cylinder head cover. The mounting structure for the cylinder head cover comprises a double-end stud through which a cylinder head and the cylinder head cover are connected. A damping pad is arranged on the double-end stud and located above the cylinder head cover. The double-end stud is sleeved with a damping bushing, and the damping bushing sequentially penetrates through the damping pad and the cylinder head cover and connected with the top surface of the cylinder head in a contact mode and tightly presses the damping pad. A lock nut is arranged on the portion, above the damping bushing, of the double-end stud, and the damping bushing, the damping pad and the cylinder head cover are locked on the cylinder head through the lock nut. A gapis formed between the cylinder head cover and the cylinder head. An elastic ring which is used for sealing the gap is also arranged between the cylinder head cover and the cylinder head. The mountingstructure is simple in structure, the cylinder head cover is mounted through flexible connection based on non-metal materials, vibration transmitted to an engine from the cylinder head can be effectively isolated, radiation noise of the cylinder head cover is lowered, and the cylinder head and the cylinder head cover are protected against damage.
