A flexible rail comprises rail pieces arranged in line, laterally opposed side plates, and laterally opposed connecting plates. Each rail piece includes a generally I-shaped member and a shelter member which is fixed to a top of the I-shaped member. The opposed side plates are fixed to respective side walls of the shelter member. The side plate overlaps one side of the rail piece. The connecting plate is fixed to a rear one of adjacent side plates, and is connected to the front side plate for pivotal movement. Thus, the rail piece, the side plates fixed thereto, and the connecting plates fixed to the side plates, as one body, are capable of pivotal movement. The rail piece, the side plate, and the connecting plate each may include an upper tapered portion with opposed upper inclined end faces starting from longitudinally opposed ridges, respectively, and a lower tapered portion with opposed lower inclined end faces starting from the longitudinally opposed ridges, respectively, except that a foremost rail piece and a rearmost rail piece each have an inner upper inclined end face starting from an inner ridge and an inner lower inclined end face starting from the inner ridge and an outer straight end face, and a foremost side plate and a rearmost side plate each have an inner upper inclined end face starting from an inner ridge and an inner lower inclined end face starting from the inner ridge and an outer straight end face. All the ridges are located at the same level.
