A groove portion 701b is formed in the corner portion 43b of the flange portion 43a, which is the edge portion 70c. The groove portion 701b is configured by cutting out a rectangular edge portion 70c (lower surface 70b). The harness 50 can be passed through the groove 701b.

Therefore, since the harness 50 can be passed through the groove portion 701 b, the harness 50 attached to the first guide member 51 a can be moved along the outer surface of the main body 43.
According to the above operation device 25, by arranging the harness 50 so as to turn around the shaft 41, when the shaft 41 swings forward, back, left, and right, the stress applied to the harness 50 ( Force) can be dispersed, and stress can be prevented from being concentrated on a predetermined portion of the harness 50. Moreover, the harness 50 can be stably held around the shaft 41 (helical state) by the guide members 51 (the first guide member 51a and the second guide member 51b).

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims. In the above-described embodiment, the operating device 25 includes the main body 43 and the operating valve 46, that is, the operating unit 42. However, instead of this, the operating device 25 that does not include the operating unit 42 is also applicable. is there. In this case, the harness 50 only needs to extend from one end (lower end) of the shaft 41 toward the other end (upper end) while turning around the shaft 41.
