An automobile air conditioner for use in an automobile which has a generally rectangular box casing curved along a curvature of the ceiling of automobile and having an air inlet and an air outlet defined at opposite sides thereof, a generally elongated evaporator accommodated in the casing adjacent to the air inlet, a cylindrical blade wheel connected with a motor with their axes in a alignment for generating air flow through the evaporator, a stabilizer extending under the fan unit toward the air outlet, an air flow deflector for controlling the direction of air flow between the fan unit and the air outlet, and a diffuser with a beam on its lower surface for controlling the air flow above the cylindrical blade wheel toward the air outlet. By this structure, a flat and compact type of air conditioner for use in an automobile is provided.

A lining material superior in abrasion-proof, considerably reducing the sliding sounds to be caused at high speeds, and an ultrasonic wave driven motor using the lining material (9) for the inverted face of a rotor (2). The lining material is composed of total aromatic polyamide pulp granule of a meta type and/or total aromatic polyamide fiber of a meta type as main comonents, being 3 through 40% in the percentage of voids. As the lining material (9) is used as the inverted face of the rotor portion (2) which comes into contact against the vibration amplifying portion (5) of the stator portion (1), so that the noises during the driving operation may be reduced, and also, the service life of the inverted face may be extended.
