The sliding member has a second engaging portion and is slideable between a transmission position in which the second engaging portion engages with the first engaging portion and a release position in which the second engaging portion disengages from the first engaging portion. A wheelchair includes two transmission devices associated with two rear wheels and two footrests. The footrests can be actuated when the rear wheels move.
