To provide a vehicle air conditioner which can reduce an amount of metal powder flowing from a motor to the evaporator side.SOLUTION: A blower unit 2 includes: a fan 20; a motor 21 having a rotary shaft part 211 which rotationally drives the fan 20, a commutator which rotates with the rotary shaft part 211, and a brush which contacts with the commutator; and a cover 5 which is installed between the fan 20 and the motor 21 so as to cover the motor 21. The cover 5 has an umbrella-shaped body which spreads toward the end from an inner peripheral edge part 51 to an outer peripheral edge part 52. The motor 21 includes a motor case 212 formed with cooling hole parts 210 allowing communication between an interior and an exterior of the motor 21. The cover 5 includes cover through hole parts 50 which penetrate through the cover 5 and allow communication between a cover rear space 5a provided between the cover 5 and the motor 21 and a fan side space 5b provided between the cover 5 and the fan 20.SELECTED DRAWING: Figure 2
【課題】モータから流出する金属粉について蒸発器側への流下量を抑制できる車両用空調装置を提供する。【解決手段】送風ユニット2は、ファン20と、ファン20を回転駆動する回転軸部211、回転軸部211とともに回転する整流子および整流子に接触するブラシを有するモータ21と、モータ21を覆うようにファン20とモータ21との間に設置されたカバー5とを備える。カバー5は、内周縁部51から外周縁部52にかけて末広がりとなる傘状体である。モータ21は、モータ21の内部と外部とを連通する冷却用穴部210が形成されたモータケース212を備える。カバー5はカバー5を貫通し、モータ21との間に設けられたカバー裏空間5aとファン20との間に設けられたファン側空間5bとを連通するカバー貫通穴部50を備える。【選択図】図2
