る変速装置の二重噛合防止機構。 The single output shaft 6 is multi-stage shifted by the two transmission paths 2, 3 and the transmission mechanisms 4, 5 provided therein, and the shift forks 14, 15 in both transmission mechanisms 4, 5 are individually controlled. Shifter section 2 operated by provided operating levers 23 and 24
1 and 22, the shifter portions 21 and 22 are connected to shift shafts 19 parallel to each other.
, 20, and an arcuate groove 2 centered around both shift shafts 19, 20 in one 21 or 22 of these shifter parts 21, 22.
By forming a guide groove G consisting of 5 and 26 and protruding a pin portion 27 that engages with the guide groove G on the other 22 or 21, one of the transmission mechanisms 4 or 5 is formed. A double mesh prevention mechanism for a transmission device, which is configured such that only when a transmission mechanism 5 or 4 is in a neutral position, the other transmission mechanism 5 or 4 can be shifted to a position other than the neutral position.
