To provide a wheelchair that even a person who can not stand up by himself/herself can transfer even from the floor of a Japanese room such as a tatami mat and pick up an object placed on the floor in the case his/her hands are available, safely transfer from a bed and is turned to the standing height of a healthy person.

In this wheelchair 1, a seat 30 is constituted so as to be elevated and lowered from the prescribed height state as a chair to the almost floor surface level. The seat 30 has a deformation part 40 including a front plate pivoted to the front end of the seat 30 and turned to a downward angle at the time of the height state. By the lowering of the seat 30 from the height state to the floor surface level, the deformation part 49 abuts on the floor surface and successively is pushed out to the front of the wheelchair while being guided by the floor surface and the front plate 41 forms a slope from the seat 30 to the floor. Further, the seat 30 is constituted so as to be elevated and lowered in an upper direction from the prescribed height state as the chair.
