Title: Valve clearance adjusting mechanism of valve actuating apparatus
Inventor: KAWAHARA KAZUCHIKA
IPC: F01L1/20
Filed: 2001-02-23
Abstract: PROBLEM TO BE SOLVED: To prevent a pivot from changing an adjusted position in its axial direction when the previously adjusted pivot is brought into locked in a rotation regulating condition. SOLUTION: When a taper member 34 is moved to a locking position, movable pins 31 are outwardly pressed in the radial direction against the inner periphery of the female screw hole 23, the pivot 21 is locked under the rotation regulating condition by the friction force caused by a pushing pressure. When the taper member 34 is moved to a lock releasing position, the pushing pressure to the inner periphery of the female screw of the movable pin 31 is released so that the pivot 21 becomes rotatable. Since the frictional resistance force in locking is made to cause by the pushing force in the radial direction, the pivot 21 is not displaced in the axial direction causing the adjusted position.
