PROBLEM TO BE SOLVED: To fix the member with free layout in the neck part of operation handle, repair and change with ease by making it possible to divide the neck part of handle, on which the rotation-operable head part is mounted, into multiple members. SOLUTION: The operation handle is comprised of a neck part 7, which is to mount to a main body frame, a hemispherical head part 8, which is a gripping part, a coupling ring 9, which combines the neck part 7 with the head part 8, a discoid rotation member 10 and a connecting rod 11, which is extended from the center of rotation member 10. The neck part 7 is divided lengthwise in two by the face that passes the central axis. A screw hole 12a is set on the nearby bottom of one neck part B, a screw boss is set on another neck part A, and it is possible for the neck parts A, B to divide and assemble. A reinforcing rib 14a is extended to the connecting face at the area, which is difference in level, inside of neck parts A, B to partition into multiple parts. The around central axis, which is to be insert with a connecting rod 11, is a hollow and a fixing rib for member 14b is set on near the roughly central part and the opening part of inside of neck parts A, B. |
