The stent graft delivery device includes a shaft on which the stent graft is placed on the distal side； a sheath which is slidable outside of the shaft； a handle which is provided on the proximal side of the shaft and the sheath； and an operation unit which is provided with a switch mechanism. When a rotating member is rotated, while in a state of pressing a switch member of the switch mechanism inward, the sheath moves backward and the shaft moves forward using the handle as a reference.
