Abstract: A sliding door apparatus capable of effectively restraining sliding movement of a door body is provided. A sliding door apparatus 1 includes: a rail 20 having an inner surface 24 formed to have a concave shape, the inner surface 24 having a first support surface 24A and a second support surface 24B which are not parallel to each other; a hanger 30A, 30B having a first driving member (32, 37) in rolling contact with the first support surface 24A, and a second driving member (33, 38) in rolling contact with the second support surface 24B; and a door body 40 configured to be moved in a longitudinal direction of the rail 20 through the hanger 30A, 30B. When seen along the longitudinal direction of the rail, the first support surface 24A and the second support surface 24B are formed to come close to each other as they extend toward a bottom of the inner surface 24.
