Zusammenfassung:	PURPOSE:To provide an insert-fitting device enabling insert-fitting work without adjusting the end parts of a pair of pipes. CONSTITUTION:A pipe insert-fitting device has three or more diameter enlarging claws 5 for enlarging the diameter of the end part of a large diameter pipe 7, an air supply port 6 for blowing compressed air inward of the end part from the diameter enlarging claws 5, a means for inserting a small diameter pipe 9 into the diameter-enlarged large diameter pipe, and a means for pulling the diameter enlarging claws 5 out of the large diameter pipe 7 and the small diameter pipe 9. Since insert-fitting can be performed even when the end part of the small diameter 9 is not conformed to the end part of the large diameter part 7, there is no need of manual work so as to enable full automation.
