Abstract
An extending and retracting device for a vehicle step includes a mounting bracket adapted to be fixed to a vehicle body and a step bracket adapted to be connected to a step member of the vehicle step. First and second arms each defines a lower end portion connected to the step bracket and an upper end portion. A third arm defines an upper end portion rotatably connected to the mounting bracket and a lower end portion rotatably connected to the upper end portion of the first or second arm. The upper end portion of the other of the first or second arm is rotatably connected to the mounting bracket. At least one arc-sliding member is mounted to the step bracket. At least one arc slot is formed in the lower end portion of the second arm. The arc-sliding member is adapted to fit into the corresponding arc slot so as to be slidable in the arc slot so that the lower end portion of the second arm is rotatable with respect to the step bracket.
