PROBLEM TO BE SOLVED: To facilitate on-site confirmation of presence/absence of occurrence of fixation of a rotary shaft of an angle sensor.SOLUTION: A fixation mark member 27A is attached to a movable part 26c of a pin pressing spring 26 for bringing a connection pin 22 provided in a control valve 200 into press-contact with one side wall (lower side wall) 23a1 of a long hole 23a of a feedback lever 23. The fixation mark member 27A is positioned at a rear surface of the feedback lever 23 in a regular attachment state of the pin pressing spring 26. If the rotary shaft of the angle sensor 4 becomes non-rotatable, a movable part 26b of the pin pressing spring 26 is pushed up by movement of the connection pin 22 against biasing force of the pin pressing spring 26 due to movement of a valve shaft 20, and the fixation mark member 27A is exposed from a rear surface of the feedback lever 23. Thereby, it is possible to find occurrence of fixation of the rotary shaft of the angle sensor 4. |
