In this vehicular air-conditioning device, an inner wall surface along a width direction of an air-conditioning casing is provided with guide portions each extending in a vertical direction. The guide portions are recessed on the outside in the width direction, forming recesses with respect to the inner wall surface. When an evaporator is inserted from above the air-conditioning casing and assembled inside, second seal portions of side plates disposed on side surfaces of the evaporator are respectively inserted into the guide portions, whereby the evaporator is guided along the vertical direction. The guide portions further include an entry portion disposed at an upper end portion of a first guide wall and expanding in a direction away from a second guide wall. Thus, the evaporator can be inserted into the air-conditioning casing from above in a preferable manner.

1. A vehicular air conditioner comprising an air conditioner casing, a passage provided in an interior of the air conditioner casing to flow air, and a heat exchanger disposed in facing relation to the passage in the interior of the air conditioner casing, wherein: the heat exchanger includes a pair of tanks disposed with an interval provided mutually therebetween, plural tubes disposed between the tanks and opposite ends of which are connected respectively to the tanks, and side plates provided on both ends of the tanks in a longitudinal direction of the tanks, and which are disposed substantially in parallel with the tubes;on the side plates, there are provided rail members extending in a longitudinal direction of the side plates, and projecting in directions away from the tubes with respect to the side plates;in the air conditioner casing, there are provided an insertion opening through which the heat exchanger is inserted, and a pair of guides extending toward an inner side in an insertion direction from the insertion opening, the pair of guides being configured to guide the heat exchanger along inner wall surfaces of the air conditioner casing by abutment against both rail members; andeach guide of the pair of guides including a first guide wall and a second guide wall which have different lengths in the insertion direction, and ends of the first and second guide walls which are facing the insertion opening are offset from one another in the insertion direction. 2. The vehicular condition according to claim 1, wherein: the rail members are seal members configured prevent leakage of air through gaps between the heat exchanger and the air conditioner casing by abutment against the air conditioner casing; andthe guides comprise sealing parts extending toward the inner side in the insertion direction from the insertion opening, and abutting against surfaces on the seal members that are substantially parallel with the side plates. 3. The vehicular air conditioner according to claim 1, wherein the pair of guides are formed by projecting the air conditioner casing outwardly in directions away from the heat exchanger. 4. The vehicular air conditioner according to claim 2, wherein the seal members provided on the side plates are formed integrally with seal members that are installed on the tanks. 5. The vehicular air conditioner according to claim 1, wherein the guides include inlet portions therein, which are formed to expand gradually toward a side of the insertion opening. 6. The vehicular air conditioner according to claim 2, wherein a width dimension of each of the seal members is smaller than a distance between the first and second guide walls of each of the pair of guides. 7. The vehicular air conditioner according to claim 1, further comprising a blower opening, wherein the insertion opening is positioned at an upper portion of the air conditioner casing, and the blower opening is aligned with the insertion opening, andthe first and second guide walls of each of the pair of guides are aligned along a direction which is the same direction along which the blower opening and the insertion opening are aligned. 8. The vehicular air conditioner according to claim 1, further comprising a blower opening, wherein the insertion opening is positioned rearward of the blower opening in an air flow direction through the heat exchanger and at an upper portion of the air conditioner casing,the first and second guide walls of each of the pair of guides are aligned along the air flow direction with the first guide wall upstream of the second guide wall, andthe first guide wall of each of the pair of guides is shorter in the insertion direction, than the second guide wall of each of the pair of guides. 9. The vehicular air conditioner according to claim 1, further comprising a cover member configured to cover the insertion opening after the heat exchanger has been inserted in the air conditioner casing, wherein the insertion opening is positioned at an upper front side portion of the air conditioner casing,the first and second guide walls of each of the pair of guides are aligned along an air flow direction through the heat exchanger, andthe first guide wall of each of the pair of guides is positioned closer to the front side portion and is shorter in the insertion direction, than the second guide wall of the pair of guides.
