This invention is to provide a bed apparatus capable of easily and properly changing a height in several steps with a simple structure. A support link and a reception link in which a slider is slidably housed are pivotally disposed in a base. An engaging pin is formed on the support link. A guide portion having a plurality of engaging portions formed at predetermined intervals along the longitudinal direction is formed in the reception link. The engaging pin is slidably inserted into the guide portion. When the reception link is pivoted, the slider inhibits or allows the engaging pin to engage with the engaging portion in accordance with the pivot direction of the reception link.
