Summary:PURPOSE:To reduce labor of fabrication thereby to reduce cost by forming a body of an operation handle by die casting and forming a recess and protrusion for locking a plate-shaped key part by press working. CONSTITUTION:A plate-shaped key part 2 at the end of a body 1 of an operation handle is inserted into a key groove 10 provided in a rotary magazine 15 so that driven pins 11a, 11b in the groove 10 are opposed to recesses 6a, 6b for rear surface key of the part 2, respectively thereby pushing the pins rearward. As a result, a locking shaft 13 is released from a fixed magazine 14 secured to a door 9 and the shaft 13 can be rotated in association with rotation of the handle 5 and a receiving part 12 follows the rotation of the shaft 13 so that the door 9 is opened with respect to a fixed frame 17. By such constitution, the body 1 can be formed by die casting and the recesses and protrusions for locking of the part 2 can be formed by press working. Consequently, labor for fabrication and cost can be reduced.
