A wheelchair comprises a seat, a first armrest disposed at one side of the seat, a second armrest disposed at the other side of the seat, and a desk plate which is arranged on the first armrest in a collapsible manner. The desk plate comprises a rotary arm part with one end pivoted to the front end of the first armrest, and a plate part pivoted to the rotary arm part. The rotary arm part is rotatable between a folding position and an unfolding position relative to the first armrest. At the folding position, the rotary arm part and the first armrest are overlapped and aligned with each other. At the unfolding position, the rotary arm part is located in front of the first armrest. The plate part can be unfolded toward the second armrest by using the rotary arm part as an axis to allow users to place objects thereon.
