Claims

[Scope of utility model registration request]

The operation section 22 of the main transmission section 13 for driving, which can be switched forward or backward, and the operation section 25 of the auxiliary transmission section 14, which can be switched freely between high and low speeds, are linked to one shift lever 20, which can freely swing in a cross direction. At the same time, by operating the speed change lever 20 in a first direction, the traveling auxiliary speed change section 14 is switched, and the first lever is moved along a second direction perpendicular to the first direction and opposite to the first lever. The first lever guide side edge 31 of the guide side edge 31 and the second lever guide side edge 32
By operating the speed change lever 20 along the second lever guide side edge 32, the main speed change section 13 for traveling is switched while the auxiliary speed change section 14 for travel remains at low speed, and the main speed change section 13 is switched along the second lever guide side edge 32. The gear shift lever 20
By operating the traveling sub-transmission section 14
The driving main transmission section 13 is configured to switch while the main transmission section 13 remains at a high speed, and the operation positions N ₁ , F ₁ , F ₃ , F on the side of the first lever guide side edge 31
the first uneven portion 35 that engages and disengages the gear shift lever 20 operated in _{step 5} , and the operating positions N ₂ , F ₂ , F ₄ , F on the side of the second lever guide side edge 32;
A shift lever positioning tool 33 having a second uneven portion 36 that engages and disengages the shift lever 20 operated in _{step 6}
is a structure of an operation part in a traveling transmission in which the operating part is swingably attached to an engagement position and a disengagement position and is biased to an engagement position, wherein the operation part is attached to the first lever guide side edge 31 side. Main transmission section 1 for driving
a first operating portion 38a that releasably receives the shift lever 20 operated to the operating position _N1 , where the drive main transmission section 13 is in the neutral position, from the operating position R1, where the main transmission section ₁₃ is in reverse; The shift lever 20, which is operated to the operation position _N2 where the main transmission section 13 for traveling is in neutral on the side of the second lever guide side edge 32, is moved to the operation position _R2 where the main transmission section 13 for traveling moves backward. A shift checker 38, which is provided with a second operating portion 38b that is releasably received from the side, is attached to the support shaft 34 of the shift lever positioning tool 33 so as to be swingable between an operating position and an action release position. A structure of a transmission section in a traveling transmission device provided with a mechanism 37 for biasing a tool 38 to an operating position.
