To provide a transfer device not generating a load by a rolling moment even if a side part of a fork piece is downwardly deflected by the load and capable of smoothly sliding a linear motion guide.

The transfer device is provided with a slide fork in which a plurality of fork pieces 1 superposed in a vertical direction are expanded/contracted in a horizontal direction. The upper and lower fork pieces 1 are slidably connected to each other through a linear motion block 3 of the linear motion guide and the linear motion rail, and the fork piece 1 at the uppermost stage of the linear motion guide and the linear motion block 3 are pivotably connected through a pin 5.
