A foldable ramp (1) for a vehicle (4) with a lowered floor well (5) in the vehicle's rear part is connected to pivotally attached tiltable side parts (8) and it moves along with them between the entry position (A) and the transport position (B). The ramp can be folded into the passive position (C) inside the vehicle (4) by means of rotationally translational movement of the carriers (7) in respect to the tiltable side parts (8). The carriers (7) are arrested with releasable single levers (11) attached to the tiltable side parts (8). Manual control of the foldable ramp (1) is made easier by springs (25) and a rope (26) conducted on pulleys (28, 29, 30, 31) to the carriers (7).
