Abstract: A recess that is provided at an end of a first case body includes an inner wall facing an air duct, an outer wall located on an outer side of a housing, and a bottom. A protrusion that is provided at an end of a second case body includes a tapered portion whose thickness in a cross sectional view gradually decreases from the second case body toward the bottom of the recess. The tapered portion is fitted between the inner wall and the outer wall of the recess. A taper angle is formed by a surface of the tapered portion facing the outer wall and a surface of the tapered portion facing the inner wall. The taper angle is larger than an internal angle formed by a surface of the outer wall facing the inner wall and a surface of the inner wall facing the outer wall.

Abstract: A vehicular air conditioning unit includes an air-conditioning case and a blower. The blower includes a blower fan accommodated in the air-conditioning case and configured to rotate about a fan axis to cause the air to flow through the case passage, and a blower motor accommodated in the air-conditioning case and configured to rotate the blower fan. The air-conditioning case includes a case body having a case opening hole that is located outward of the blower in a radial direction of the fan axis and opens in the radial direction, and an opening hole cover fixed to the case body to close the case opening hole. The opening hole cover is detachable from the case body. The case opening hole has a size that allows the blower to pass through the case opening hole when the blower is taken out from the air-conditioning case.
