Abstract
A mechanical adjuster that automatically increases or decreases or decreases valve clearance is provided that includes: a housing () having threaded portions (); a threaded member () thread-coupled with the threaded portion (); a threaded member () connected to the threaded member () via mutual rotation prevention-couplings () and thread-coupled with the threaded portion (). When a load acting on the threaded member () is equal to or less than a valve closing load, valve clearance is decreased by an integrated rotation of the threaded members (). with a slip torque of the threaded member ()>a self-locking torque of the threaded member (). When a load acting on the threaded member () is close to or exceeds a valve opening load, valve clearance is increased by an integral rotation of the threaded members () with the absolute value of a slip torque of the threaded member ()>a self-locking torque of the threaded member ().
