徴とする走行伝動装置の操作レバー構造。 By rotating the operating lever 14 around the second fulcrum shaft 18, the operating arm 1 of the forward and reverse systems of the continuously variable transmission mechanism 3 is rotated.
1a and 11b, the operating arm 12 of the forward/reverse switching mechanism 4 is switched, and the operating arm 12 of the operating lever 14 is rotated about the first fulcrum shaft 15 provided orthogonally to the second fulcrum shaft 18. In the operation lever structure of the traveling transmission device 1 including the continuously variable transmission mechanism 3 and the forward/reverse switching mechanism 4 that performs the speed change operation of the operating arms 11a, 11b of the selected continuously variable transmission mechanism 3, the forward/reverse switching mechanism 4 is provided. The arch-shaped arm 23 linked to the operating arm 12 is supported at two points coaxially with and straddling the second fulcrum shaft 18. In addition, an arch-shaped arm 23 linked to the operating arm 12 is supported at two points coaxially with and straddling the second fulcrum shaft 18. When viewed, a U-shaped U-shaped font 21 is formed, and this U-shaped font 2
1. An operating lever structure for a travel transmission device, characterized in that an arch-shaped arm 23 is inserted into the lever.
