ABSTRACT:
A protecting member of the invention is used for a gasket situated between two engine parts. The protecting member includes a spring member situated between the two engine parts and located around bolt. When the bolt is tightened, the spring member abuts against the engine parts and is compressed to provide predetermined pressure to the bolt through the engine parts. Thus, when an outward force applied to the bolt increase, an amount of the outward force exceeding the predetermined pressure, i.e. the tightening pressure, is only applied to the bolt to absorb a part of the outward force. When an inward force applied to the bolt decreases, the predetermined pressure of the spring member acts against the inward force applied to the bolt. Thus, the pressure changes to the gasket is reduced to prevent creep relaxation of sealing means of the gasket.
