A vehicle slope apparatus includes a slope plate configured to be deployed at a lower end of a door opening portion, a guide rail extending in deployment and housing directions of the slope plate, a moving member configured to move along an extending direction of the guide rail, a support arm rotatably connected to a rear end of the slope plate and rotatably connected to the moving member, and a lift mechanism configured to lift the rear end of the slope plate by rotating the support arm in a state where the slope plate is deployed. The support arm is provided with a roller configured to hold a moving posture of the slope plate by being in sliding contact with the guide rail in a state where the slope plate is moved integrally with the moving member.

Vehicle slope apparatus

A vehicle ramp device includes a ramp plate deployed at a lower end of a door opening, a moving body moving in a deploying or retracting direction of the ramp plate, a support arm rotatably connected to the ramp plate and the moving body to allow a rear end portion of the ramp plate to be lifted up when the ramp plate is deployed, a fall prevention member rotatably connected to the ramp plate, an urging member urging the fall prevention member to make it stand on a side end portion of the ramp plate, and a pressing member abutting against the fall prevention member that moves downward together with the ramp plate having been lifted up based on a rotation of the support arm and pressing the fall prevention member to bend it on a top surface of the ramp plate against an urging force of the urging member.

Vehicle ramp device

A vehicular slope apparatus includes: a slope plate deploying to a lower end of a door opening portion; a guide rail extending in a deploying and storing direction of the slope plate; a drive shoe moving in an extending direction of the guide rail; a link member having a first connection point rotatably connected to a rear end portion of the slope plate and a second connection point rotatably connected to the drive shoe; a posture holding mechanism configured such that the slope plate moves in the extending direction of the guide rail in conjunction with the drive shoe; and a lift mechanism configured to form a rotation fulcrum of the link member between the first and second connection points and to rotate the link member by changing an interval between the rotation fulcrum and the second connection point to thereby lift the rear end portion of the slope plate.

Vehicular slope apparatus

A ramp apparatus for a vehicle includes a ramp retractable in the vehicle and drawable to an outside of the vehicle, a moving body movable in a drawing direction and a retracting direction together with the ramp, a support arm rotatably coupled with the ramp at a first rotatable coupling point and rotatably coupled with the moving body at a second rotatable coupling point, and a tension spring interposed between the ramp and the moving body. The ramp is arranged in a lifted-up position in which the ramp faces a door opening of the vehicle from a drawn position. The tension spring rotationally urges the first rotatable coupling point positioning above the tension spring in the drawn position of the ramp about the second rotatable coupling point and exerts an urging force on the ramp, the urging force moving the ramp from the drawn position toward the lifted-up position.
