A jack for a vehicle includes a main frame fixed to an underside of a vehicle. A screw rod extends through two end plates that are respectively formed on two ends of the main frame. A movable member and a fixed member are respectively mounted on the screw rod. A lower supporting member includes a lower end in contact with the ground and an upper end pivotally connected to the movable member. The connecting member includes a first end pivotally connected to the fixed member and a second end pivotally connected to an intermediate portion of the lower supporting member. The lower supporting member and the connecting member are moved to a position for supporting the vehicle when the screw rod is turned in a direction. The lower supporting member and the connecting member are folded when the screw rod is turned in a reverse direction.
