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 point management system using a vehicle as a contact point includes: an evaluation device that evaluates a specific activity of an user of the vehicle based on vehicle information according to a travel state of the vehicle or activity information recorded in a smart device of the user; a point giving device that gives the point to the user according to an evaluation by the evaluation device; and a propose device that proposes, to the user, an activity for which the point is given. The specific activity includes at least one of three categories of an eco-driving activity, a health care activity, and a social contribution activity.

Abstract: A blower includes a centrifugal fan and a partition wall disposed in a suction space in the centrifugal fan. The partition wall has a base portion extending along a fan central axis to partition the suction space into a first space for a first fluid and a second space for a second fluid. The partition wall has an enlarged portion connected to an end of the base portion on another side of the fan central axis. The enlarged portion covers a part of a fan boss. A clearance passage is defined between the enlarged portion and the fan boss and has a first space side opening and a second space side opening. The enlarged portion is biased in the suction space to the second space such that a pressure at the second space side opening is less than a pressure at the first space side opening.

Abstract: An air conditioning unit for a vehicle includes: an air conditioning case defining an in-case passage in which air flows to a vehicle interior; a cooler arranged in the air conditioning case and configured to cool the air flowing in the in-case passage; a blower that includes a blower motor and an impeller configured to be rotated by the blower motor and generate an air flow in the in-case passage; and a cooling passage portion defining a motor cooling passage in which air flows to cool the blower motor. The blower is arranged downstream of the cooler with respect to the air flow in the air conditioning case. The motor cooling passage includes a passage inlet located downstream of the impeller with respect to the air flow in the in-case passage, and a passage outlet located upstream of the impeller with respect to the air flow in the in-case passage.

Abstract: An air-conditioning unit for a vehicle includes an air conditioning case, a blower, and a rectifying mechanism. The blower has a blower fan rotating around a fan axis and arranged in an in-case passage of the air conditioning case, and blows out air drawn from one side in an axial direction of the fan axis by rotation of the blower fan. The rectifying mechanism is arranged downstream of the blower fan in the in-case passage, and the air passes through the rectifying mechanism. The blower fan is arranged so that the other side of the fan axis that is opposite to the one side extends toward a downstream side of the in-case passage. The rectifying mechanism suppresses a swirling flow generated by the rotation of the blower fan in the air blown out from the blower fan as compared with the blown-out air prior to flowing into the rectifying mechanism.

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.

Abstract: In an air conditioning case, a blower sucks air flowing out from first and second upstream side ventilation paths from one side in an axial direction of a fan axis by rotation of a blower fan and allows the sucked air to flow to first and second downstream side ventilation paths. An upstream side guide member is provided on one side in the axial direction with respect to the blower fan and guides the air to the blower fan. Further, the upstream side guide member has a twisted shape and guides the air to the blower fan along the twisted shape.
