Abstract: A handling unit comprises: a collet integrally having a reference part, a plurality of elastic deformation parts connected to the tip side of the reference part, finger parts respectively connected to the tip sides of the elastic deformation parts, and a driven part that receives a driving force; a housing having a cylinder structure formed on the base end side or the outer circumferential side of the collet and provided with a fluid supply port and having a collet locking part that locks the collet at a locking position; and an operation body having a driving part that imparts a driving force to the driven part, a pressure reception part that receives the pressure of a fluid supplied from the fluid supply port, and a cylinder slide contact part that makes slide contact with the internal surface of the cylinder structure.
