[Issue] To provide a bending instrument for an endoscope with which a linking part which joins a sliding part and a fixed part reliably returns to its original state after having bent so that there is no impediment to operation, and furthermore with which the endoscope does not become soiled, and an endoscope set which uses the same. [Means of Resolution] A bending instrument 10 for an endoscope which is attached to the tip end of a sheath 27 for covering the endoscope 20, and which causes the tip end portion of the endoscope 20 to bend consists of: a fixed part 12 which is attached to the outer periphery at the tip end of the sheath 27 a sliding part 13 which is slidably attached further towards the base end of the sheath 27 than the portion where the fixed part 12 is attached a flexible linear linking part 14 for joining the fixed part 12 and the sliding part 13 and a spacer 11 comprising a coil spring which is fitted on the outer periphery of the sheath 27 between the fixed part 12 and the sliding part 13. Furthermore, an endoscope set consists of the bending instrument 10 for an endoscope, the endoscope 20, the sheath 27 and a gastrostomy catheter 40.
