PROBLEM TO BE SOLVED: To provide an operation handle used for a valve, capable of appropriately maintaining a fitting state of a protective cover with respect to a handle main body and replacing the protective cover. SOLUTION: Lock claws 14g are formed on end faces in right and left sides of an inclined part 14b formed at a tip of a horizontal part 14a of the handle main body 14. The horizontal part 14a and the inclined part 14b of the handle main body 14 are covered with the protective cover 17 made of synthetic resin. In this state, an inner face of the protective cover 17 is locked by the lock claws 14g. Due to this, the protective cover 17 is mounted so as not to easily be detached from the handle main body 14 by mischief and an external shock. When replaced, the protective cover 17 is removed by resisting coming-off stop resistance of the lock claws 14g, and replaced with another protective cover 17. COPYRIGHT: (C)2006,JPO&NCIPI
