In a vehicle air conditioner for a vehicle cabin interior is split into a plurality of air-conditioned zones, that is capable of independent air conditioning control for individual air-conditioned zones, provided is a solar radiation sensor that measures solar radiation levels individually for a first air-conditioned zone and a second air-conditioned zone adjacent thereto; a judging unit () that judges whether or not a difference between the solar radiation level of the first air-conditioned zone and the solar radiation level of the second air-conditioned zone falls within a predetermined range; a first controller () that performs identical air conditioning control for the first air-conditioned zone and the second air-conditioned zone when the difference falls within the predetermined range; and a second controller () that performs independent air conditioning control individually for the first air-conditioned zone and the second air-conditioned zone when the difference falls outside the predetermined range.

A dial type switch mechanism is developed in which an installation space can be made as small as possible. In a dial type switch mechanism () furnished with a push type switch part provided in its center, and a dial switch part which operates a dial fitted around the push type switch part, there are provided: a substantially cylindrical dial knob (), in the center of which a cavity is provided for the push type switch part to be installed; a ring-shaped joint ring (), which is supported such that it can rotate freely relative to a front panel () and connects and rotates together with the dial knob (); and a rotary bracket (), which is joined to the joint ring (), and in which a switch rotation shaft () that operates the dial type switch part is connected together with a ring-shaped member () via an arm ().

In a vehicular air conditioner, in which an air flow passage for directing air sucked horizontally through a suction port upward in a casing having a plurality of blowout ports at the upper part and said suction port at the lower part, and an evaporator, air mix damper, heater, and blowout mode switching damper for selectively switching the plural blowout ports are arranged in the air flow passage, the evaporator can be replaced easily and rapidly, and the contamination of the surroundings, caused by the drain which drops from the evaporator when the vehicle is inclined and flows back into the blower case and drops from it by leaking, is prevented. For this purpose, the evaporator is disposed at a portion where the direction of air changes from horizontal to upward in the air flow passage so as to be tilted in such a manner that the suction port side end thereof is high than the opposite side end, and the casing is divided into a plurality of sections, and also one of the divided casings forms the upper half part of the suction port and is configured as an evaporator detachable cover for covering one side of the evaporator so that the evaporator can be pulled out of the casing by removing the cover.
