To provide a lift device of light weight and low cost to solve the problem of heavy weight and high cost due to a large number of components in conventional lift devices equipped on minivan type vehicles or the like, provided as welfare vehicles equipped with lift devices for enabling a wheelchair to easily get on and off, where the lift device is equipped with a link mechanism to elevate a platform, and a slide mechanism to horizontally move it.

Two link mechanisms 20 and 30 are connected, and they are actuated by separate drive sources 29 and 35, so that similar horizontal moving quantity to that of conventional slide mechanisms is secured with the platform 11. The slide mechanism in conventional devices is thus omitted to reduce the number of components, thereby light weight and low cost are achieved in the lift device 10.
