    • Body air outlets of an air-conditioning-apparatus indoor unit each has a substantially trapezoidal shape in plan view and are each defined by a body-air-outlet outer side wall, a body-air-outlet inner side wall, and a pair of body-air-outlet end walls. The body-air-outlet outer side wall is provided with a deflection guide at each of long-side ends thereof. The body-air-outlet end walls are each provided with a sloping guide. The deflection guide has a deflection-guide upper surface that gradually projects toward the body-air-outlet inner side wall in a direction toward a body open face (toward a downstream side) and in a direction toward the central part of the body air outlet. The sloping guide has a sloping-guide upper surface that gradually projects toward the central part of the body air outlet as the sloping guide extends closer to the body open face (toward the downstream side).
    • 空调机室内机的主体空气出口在平面图中各自具有大致梯形形状,并且分别由主体 - 空气出口外侧壁,主体 - 空气 - 出口内侧壁和一对 车身 - 出风口端壁。 主体 - 出气口外侧壁在其每个长边端处设置有偏转引导件。 身体 - 出气端壁各设有倾斜导向件。 偏转引导件具有偏转引导器上表面,该偏转引导器上表面朝向主体 - 空气出口内侧壁朝向主体开放面(朝向下游侧)朝向身体排气口的中心部分的方向突出 。 倾斜导向件具有倾斜导向件上表面,当倾斜导向件更靠近主体开放面(朝下游侧)延伸时,倾斜导向件上表面逐渐向主体空气出口的中心部分突出。
