Therefore, the invention can easily assist standing of a person having weak physical strengths, such as an old or weak person, by a simple operation, and a rotational angle of the seat can be adjusted so as to assist standing in accordance with weight and body type of the old or weak person. In addition, the standing assist chair of the present invention can assist standing and sitting of a user according to the user's weight and body type by easily adjusting a standing angle of the seat. In addition, since the link means, the gas cylinder, and the standing angle adjusting device can be configured as a single seat tilting module, the seat tilting module can be applied to various types of chairs. Specifically, the seat tilting module can be detached from the side frames for constituting side parts of a wheelchair by using a supporter.
