Abstract: [Problem] To improve a strength and productivity of a filter having a filtration member in a pleated shape. [Solution] A filter (40) includes a filtration member (41) having partitioned surfaces (43) that are partitioned by mountain-fold pleats (42) and valley-fold pleats (42), and end plates (48, 49) fixed to two end portions of the filtration member (41) and configured to maintain the filtration member (41) in a pleated shape. The filtration member (41) includes a plurality of filtration portions (45a, 45b, and 45c) and intermediate portions (46a, 46b) each provided between the adjacent filtration portions. In the filtration portions (45), an angle formed by the adjacent partitioned surfaces (43, 43) is greater than 0°, and in the intermediate portions (46a, 46b), an angle formed by the adjacent partitioned surfaces (43, 43) is 0°.

Abstract: A vehicle air conditioning device (10; 10A; 10B) has a casing (20) configuring a temperature adjustment section (12; 12A; 12B). The casing (20) has provided in a position thereof opposed to an inflow surface (41) of a heat exchanger (40) a flow direction change section (30) which causes the flow direction of air led to the temperature adjustment section (12; 12A; 12B) from a duct section (13; 13A; 13B) to bend approximately 90 degrees and leads the air to the inflow surface (41). Guide portions (60, 70; 60A, 70A; 60B) smaller in area than the flow direction change section (30) as seen when directly facing the inflow surface (41) are provided in a heat exchanger upstream space (22) between the inner wall surface of the casing (20) and the inflow surface (41).

Abstract: The present invention provides a fragrance device for a vehicle capable of supplying plural fragrant ingredients to the inside of the vehicle as being contained in air flow of a vehicle-use air-conditioning device with a simple structure. The fragrance device for a vehicle according to the present invention includes a main body 10 having a fragrance retention container 5, an inlet passage 6, an outlet passage 7, an inlet passage opening/closing door 8 and an outlet passage opening/closing door 9, an actuator 11 fixed to the main body 10, and a cam 14 which rotationally drives a rotary shaft 12 of the inlet passage opening/closing door and a rotary shaft 12 of the outlet passage opening/closing door.

Abstract: Provided is an air blowing unit for a vehicle which, even when a backflow prevention means which prevents the flow of air which flows back through a gap formed between a bottom surface of an impeller and an upper surface of a motor flange is adopted, optimally maintains a size of the gap thus suppressing noises and the collection of moisture and, can suitably boost a pressure of air in a scroll case portion. With respect to a case of an air blowing unit, a projecting portion is formed in a projecting manner on an inner side of a second wall portion on a side opposite to a first wall portion where an air suction port is formed as an air backflow prevention means. The projecting portion is positioned outside an impeller in the radial direction with a predetermined gap between a radial outer end of the impeller and the projecting portion.

Abstract: Object of this invention is to allow baffle plates with varying functions to be interchangeably mounted at a single air-conditioning system and to prevent an erroneously selected baffle plate from being mounted undetected. A unit case 3 includes a plurality of fastening structures 24 and 25 as required, each to be used in conjunction with one of the baffle plates 20A, 20B and 20C with differing functions. The baffle plates 20A, 20B and 20C each include a fastening structure that is used in conjunction with the fastening structure 24 or 25 at the unit case 3 or is used by itself when mounting the corresponding baffle plate 20A, 20B or 20C at the unit case 3.
