Arm lowering motion restricting device for working vehicle
The arm lowering motion restricting device 40 comprises an arm restricting member 41 which can be freely swung upward and downward, one end portion of which is pivotably connected to the arm 21, and which extends so as to cover the upper surface of the raising and lowering cylinder 23, a locking pin 50 which is detachably passed through the lower end portion of the arm restricting member 41, and a torsion coil spring 60 which is attached to the upper portion of the tip end of the arm restricting member 41. When the raising and lowering cylinder 23 is extended so that the tip end portion of the arm restricting member 41 contacts the end surface 23b1 of the cylinder tube 23b on the cylinder rod side, the retraction of the raising and lowering cylinder 23 is restricted. In such a state, when the first arm part 61 of the torsion coil spring 60 is caused to abut against the upper surface of the tip end of the cylinder tube 23b, the second arm part 62 is latched on the latching pin 45 of the arm restricting member 41, and the raising and lowering cylinder 23 is extended, the arm restricting member 41 is caused to swing upward so that the restriction of the retraction of the raising and lowering cylinder 23 is released.
