できる。(Effects of the invention) As explained above, the present invention fixes an annular insulating plate having a flat surface perpendicular to the drum axis to the axial end of a change drum in a transmission, and also provides a positioning and positioning plate made of a conductor. Press-fit and fix the contact pin into the pin insertion hole of the drum, insert the contact pin into the positioning hole of the insulating plate, form a flat surface with the tip of the contact pin, align it with the flat surface of the plate, and align it with the neutral plate. The switch part is arranged to face the flat surface of the plate, and the contact part of the switch part is brought into contact with the flat surface of the plate so as to contact the contact pin when in neutral: (1) Contact pin 10 and switch part 15 contact part 16
The contact range can be set accurately, and compared to the conventional device shown in Fig. 4, it is possible to prevent contact failure during neutral due to axial movement of the contact part and abnormal contact of the contact part outside the neutral range. can.
即ちニユートラル時におけるインジケータに
よるニユートラル標示が適正に行われる。 That is, the neutral indication by the indicator at the neutral time is properly performed.

またコストも安い。(2) Since the contact pin 10 is also used for positioning the plate 12 and an insulating material is used as the plate 12, it is only necessary to form a flat surface 12a on the plate and drill holes for the pin. Therefore, the structure and manufacture of the switch mechanism is extremely simple compared to the devices shown in FIGS. 5 and 6.
Also, the cost is low.
