<p>Conventionally, a wheelchair lift apparatus for a vehicle has had the problem that, when an electric flapper mounted on a platform is rotated by a manual operation, the electric motor or reduction gear assembly rotates due to the force of the manual operation and generates a high-frequency sound and other unpleasant noises. The present invention addresses the problem of preventing the generation of unpleasant noise when an electric flapper is rotated by a manual operation. The configuration is such that it is possible to switch between a power-connected state, in which a power system having a flapper drive device (20) using an electric motor as a power source is connected, and a power-disconnected state, in which the power is disconnected. Manual operation of a flapper (11) is performed in the power-disconnected state where the flapper has been moved laterally, whereby the generation of unpleasant noise by the electric motor and the like is prevented.</p> |
