Embodiment 1
[0140] In this case, in the present embodiment, the mechanical safety device 88 is composed of a power transmission portion 82f that transmits power from the first lever structure portion 82A to the second lever structure portion 82B. However, the mechanical fuse 88 is not limited to the power transmission portion 82f that transmits power from the first lever structure portion 82A to the second lever structure portion 82B. For example, if Figure 13 and Figure 14 As shown, the mechanical fuse 88 may be composed of a power transmission portion 82h that transmits power from the third shaft 81c configuring the drive shaft (output shaft) of the reduction mechanism 81 to the operating lever 84 .
[0141] Specifically, the power transmission portion 82h is composed of a plate-shaped main body having three thick portions 82y and two thin portions 82x formed between these thick portions 82y. The power transmission portion 82h is inserted into a notch portion 81z formed at the end o...
Embodiment 2
[0148] Such as image 3 As shown, in the above-described embodiment, the shift power transmission mechanism 80 is provided with a reduction mechanism 81 that reduces the rotational speed of the shift motor 70 , an operating lever 84 , a shift lever 82 , an operating lever 85 and a shift link mechanism 83 . However, the structure of the shift power transmission mechanism 80 is not limited thereto. Such as Figure 15 As shown, the shifting power transmission mechanism 80 may be composed of a reduction mechanism 81 , a shift linkage mechanism 83 and a connecting member 90 , wherein the connection member 90 connects the reduction mechanism 81 and the shift linkage mechanism 83 . For example, if Figure 16 As shown, the connection member 90 may be configured by a relatively non-rotatable element that coaxially connects the third shaft 81c of the reduction mechanism 81 and the shift operation shaft 83a of the shift linkage mechanism 83 .
[0149] Such as Figure 16 As shown, acc...
