PROBLEM TO BE SOLVED: To accurately position a neutral switch by arranging a gauge reference line to be fitted to a positioning plate and a neutral switch main body so as to coincide with each other, and eliminating a projecting piece from the positioning plate, and threadedly engaging a nut with a rotor shaft for lock. SOLUTION: A positioning plate 5 having a projecting piece 8 is press fitted into a rotor shaft 4 of a neutral switch 2, and a neutral switch main body 3 set at an N position and marked with an N reference line is installed in a tip 1 of a manual valve shaft. The neutral switch main body 3 is moved, and a gauge reference line 9 marked on the positioning plate 5 and an N reference line 3A marked on the neutral switch main body 3 are made to coincide with each other, and the projecting piece of the positioning plate 5 is eliminated. A nut 11 is threadedly engaged with a rotor shaft 4, and the left positioning plate 5 is fixed, and the nut 11 is locked. With this structure, the neutral switch can be excellently positioned. |
