A transferring apparatus includes a plurality of side-arm transfer units each provided with a pair of side arms each of which is capable of stretching toward and retracting from both sides of an object to be conveyed. The side-arm transfer units are arranged side by side in a left-and-right direction that is orthogonal to a stretching-and-retracting direction of the side arms. The side arms each include pinion gears, a rack gear, and a motor that drives the pinion gears. The motors positioned between the side-arm transfer units are connected to the pinion gears whose positions in the stretching-and-retracting direction are different from each other.
