An alignment apparatus for aligning hairpin-shaped heat-exchanger tubes at a regular pitch. An insertion position side is configured as a regular pitch alignment unit where arrangement plates are provided at an interval that is double the pitch of through-holes in a fin stack. An upstream side is configured as a wide pitch alignment unit where arrangement plates are provided at an interval equal to an integer multiple of two or more times the regular pitch alignment unit. The regular pitch alignment unit is provided with stopper apparatuses that stop the hairpin-shaped heat-exchanger tubes at different positions in an inclined direction for the respective arrangement plates. The wide pitch alignment unit is capable of moving along an alignment direction of the arrangement plates so as to allow the hairpin-shaped heat-exchanger tubes to move to the regular pitch alignment unit, where the hairpin-shaped heat-exchanger tubes are stopped at a more downstream position.

Provided is an insertion guide that performs accurate rotation correction between a shaft and a hole and phase correction between the shaft and hole. The shaft includes: a first guide portion at a distal end of the shaft having a diameter smaller than a diameter of the hole; a second guide portion, provided on a base end side of a first narrow cylindrical portion, and having a diameter smaller than the diameter of the hole and larger than a diameter of the first narrow cylindrical portion; and a third guide portion, provided at the distal end of the shaft, and is a recessed portion to be engaged with a protruding portion formed in the hole. The shaft being inclined with respect to the hole, is brought into contact with the hole at two points or less before the third guide portion is brought into contact with the protruding portion.
