受台昇降装置。 The base ends of a tension link 16 and a bendable compression link 11 that constitute a parallel link on the vehicle body frame 1 are supported so as to be swingable up and down, and the tension link 16
A support shaft 17 provided at the tip of the support shaft 17 pivotally supports the loading platform 3 so as to be able to rise and fall, and pivotally supports one end of a connecting link 19. A connecting pin 20 is attached to the other end of the connecting link 19.
A safety lock mechanism S is attached to the bending compression link 11 to restrain the bending of the bending compression link 11. When the safety lock mechanism S is activated, the tension link 1
6 and the bending compression link 11 maintain a parallel relationship, and the rocking movement of these links 16 and 11 raises and lowers the loading platform 3 in a substantially horizontal state, and when the safety lock mechanism S is not activated, the loading platform 3 is compressed. Link 1
In the loading platform elevating device for a vehicle, which allows the loading platform 3 to tilt forward and downward by allowing bending of the bending link 11 and the connecting link 19, the bending link 1. A loading/unloading platform elevating device for a vehicle, characterized in that a rolling roller 21 that can land before the tip of the loading roller 11 is rotatably supported.
