- the first link connecting portion 47c is pulled up, the first link member 48 rotates about the link swing shaft 48e, and the second link connecting portion 48b moves backward. Move to.
- the second link member 49 moves rearward, so that the guide pin 42b is attracted rearward and the gate lever 42 moves to the retracted position.
- the flip-up operating member 47 is located at the second position.
- the flip-up operation member 47 moves to the first position as shown in FIG. 11A.
- the first link connecting portion 47c is pushed down, the first link member 48 rotates about the link swing shaft 48e, and the second link connecting portion 48b moves forward.
- the second link member 49 moves forward, so that the guide pin 42b is pushed forward and the gate lever 42 moves to the cutoff position.
- the flip-up operation member 47 can also be used to flip up the first frame 20, so that the flip-up operation can be performed continuously with the retracting operation of the gate lever 42.
- the flip-up operation member 47 is further shown in FIG. 13 (a) from the first position shown in FIG. 11 (a) via the second position shown in FIG. 11 (b).
- the operation to the third position is performed, the engagement between the locking portion 46a of the flip-up stopper 46 and the pin 23 is released, and the first frame 20 is configured to flip up.
- the flip-up operation member 47 moves to the third position as shown in FIG. 13 (a).
- the first link connecting portion 47c is pulled up, and the first link member 48 rotates about the link swing shaft 48e.
- the stopper pushing portion 48d moves forward and pushes the flip-up stopper 46 forward.
- the flip-up stopper 46 swings forward against the urging force of the stopper spring 46g, and the engagement between the locking portion 46a and the pin 23 is released.
- the first frame 20 is flipped up to the upper position shown in FIG. 13B by the urging force of the flip-up damper 45b.
- the flip-up operation member 47 cannot be operated forward. That is, as shown in FIG. 13B, when the first frame 20 is flipped up to the upper position, the stopper pushing portion 48d is engaged with the upper regulating portion 46d and the tip hook 46e of the flip-up stopper 46. It fits. In this state, since the first link member 48 cannot rotate in the direction in which the stopper pushing portion 48d pushes the tip hook 46e (clockwise in FIG. 13B), the flip-up operating member 47 is operated forward. Can't be done.
- the flip-up operation member 47 is inoperably locked by the flip-up stopper 46, when the first frame 20 is flipped up, the flip-up operation member 47 is operated forward to operate the gate lever. It is configured so that the 42 cannot be moved to the cutoff position.
- the third frame 45 that supports the first frame 20 so as to be swingable up and down, and the flip-up damper 45b that urges the first frame 20 to flip up upward. It includes a flip-up stopper 46 that is attached to the third frame 45 and can be engaged with the pin 23, and a flip-up operation member 47 for operating the flip-up stopper 46.
- the flip-up stopper 46 includes a locking portion 46a capable of engaging and disengaging the pin 23, and when the pin 23 is engaged with the locking portion 46a, the first frame 20 acts as an urging force for the flip-up damper 45b.
- the flip-up structure of the console 11 can be realized by using the pins 23 constituting the tilt structure.
- the first frame 20 can be rotated with respect to the third frame 45 while maintaining the inclination of the second frame 25 with respect to the first frame 20. According to such a configuration, since the tilt position is maintained before and after the operator gets on and off, it is not necessary to reset the tilt position every time the operator gets on and off, which is convenient.
- this modification includes a gate lever 42 provided so as to be able to turn in order to prevent the driver from getting on and off the seat 10, and the gate lever 42 operates the flip-up operation member 47 to a predetermined first position. Occasionally, it moves to a blocking position that blocks the passage to the seat 10, and when the flip-up operating member 47 is operated to a predetermined second position, it moves to a retracted position retracted from the passage to the seat 10. Has been done. According to such a configuration, the flip-up operation member 47 can perform not only the flip-up operation of the console 11 but also the operation of the gate lever 42, so that the console 11 can be simply configured.
- the flip-up operating member 47 is inoperably locked by the flip-up stopper 46 so that the gate lever 42 cannot move to the blocking position when the first frame 20 is flipped up. According to such a configuration, it is possible to prevent the gate lever 42 from being accidentally moved to the blocking position when the first frame 20 is flipped up, so that safety can be improved.
