Abstract: A target thermal sensation setter sets target thermal sensations for a finite number of parts into which the occupant is virtually divided. A cabin temperature controller individually controls a cabin air-conditioning unit and an auxiliary heater so that the thermal sensations of the respective parts of the occupant estimated by an occupant thermal sensation estimator fall within a range of the target thermal sensations.

Abstract: A comfort sensation calculation unit quantitatively calculates comfort sensation of an occupant from an RRI of the occupant A, and a target control value of a thermal environment control device is set based on the comfort sensation of the occupant. Therefore, it is possible to achieve air conditioning control that reflects the comfort sensation of the occupant. When a signal output from the comfort sensation calculation unit and a signal output from the occupant thermal sensation calculation unit do not correspond to each other, the signal output from the comfort sensation calculation unit is corrected, and the target control value is determined.

Abstract: A heat accumulating unit includes an upstream heat accumulator and a downstream heat accumulator each accommodating a supercooling heat accumulating material. Each of the upstream heat accumulator and the downstream heat accumulator has a channel in which fluid flows. In heat accumulation of the supercooling heat accumulating material, the channel of the upstream heat accumulator and the channel of the downstream heat accumulator are set in a serial connection state by a serial connection pipe. In a temperature rise mode, fluid that has passed through the channel of the upstream heat accumulator flows in a bypass pipe.

Abstract: A round bar output shaft is provided and fitted into an anti-slip member so as to rotate integrally with the anti-slip member. A recess is formed on the anti-slip member to make the stress generated on the anti-slip member by the output shaft fitted in non-uniform around a periphery of the anti-slip member. While the anti-slip member is being molded, a weld line is formed in a low-stress-generating portion.

Abstract: A fan includes a cylindrical anti-slip member that is rotatable integrally with a fan body. The anti-slip member is a molded product of a resin material with higher mechanical strength than the resin material of the fan body. A round bar output shaft is fitted into the anti-slip member. Recesses are formed on the outer peripheral surface of the anti-slip member.

Abstract: A vehicle air conditioner to be installed in a passenger compartment S includes a casing, a piping component, and a seal 60. The casing accommodates a heat exchanger. The piping component supplies a heating medium to the heat exchanger or exhausts the heating medium from the heat exchanger. The seal 60 seals a portion between the casing and a periphery of an opening P of a dash panel P of a vehicle. The dash panel P separates the passenger compartment S from an outside of the passenger compartment S. The piping component is inserted into the opening. The seal 60 has a surface facing the dash panel P and including a notch 60d. The notch 60d is positioned outside the periphery of opening P1.

Abstract: A drain hose (1) includes a drain hose body (10) and a hard member (20). The hard member (20) includes a notch (22) and hooks (21). The drain hose body (10) includes a protruding portion (14) provided to a part, of an outer periphery of the drain hose body (10), to which the hard member (20) is attached. The protruding portion (14) protrudes to be positioned in the notch (22), and, when force is applied to the drain hose body (10) in a direction to pull the drain hose body (10) from a through hole (P1), depresses edge portions (22a) of the notch (22) in a direction to expand the hard member (20) in diameter.
