PROBLEM TO BE SOLVED: To provide a wheelchair with a vertically moving function capable of shortening a wheel base in association with rising of a seat. SOLUTION: This wheelchair with the vertically moving function comprises a tilting-back rod 10 rotatably coupled at its lower end to a front wheel section, a tilting-forth rod 11 rotatably coupled at its lower end to a rear wheel section and pivotally secured to the rod 10 across the rod 10 at an intermediate position, a seat 5 pivotally secured to the upper end of the rod 11, and a link rod 15 pivotally secured at its upper end to a backrest 6 and pivotally secured at its lower end to the upper end of the rod 10. The pivotally securing position and the length of the rod 15 are set to enable holding of the seat 5 in a horizontal state with respect to a change of a rods opening angle between the rod 10 and rod 11. The rod 15 is rotated with respect to the rod 10 in response to the change of the rods opening angle to hold the seat 5 in the horizontal state.
