供できる効果を有する。(7) Effects of the Invention As described above, the present invention provides an X-type link mechanism and a bellows via an intermediate plate between a substrate and a vehicle body mounting plate, and also provides a structure between the substrate and the vehicle body mounting plate. X-link mechanism is provided,
Since the vehicle body mounting plate is raised and lowered by the supply and exhaust of the bellows and the locking or unlocking of the stopper provided at the connecting pivot of the X-type link mechanism, the overall height of the jack itself can be reduced when shortening. It can be applied to low-floor type vehicles, improves the holding stability of the vehicle when it is extended, reduces the risk of damage to the bellows compared to a configuration with only bellows, and has a simpler configuration and more storage space. It has the effect that it can be provided at low cost without the need.
