PROBLEM TO BE SOLVED: To surely protect an electric compressor from external force applied to a vehicle.SOLUTION: Between a pair of mounting legs 7a respectively formed at places of a housing, which are spaced in the rotation direction of an electric motor 5, a rib 7e is protruded integrally with the housing. The rib 7e has a protrusion part 7f with a tip 7g arranged at the outermost position from the contour of the housing, and a pair of connection parts 7h respectively connecting between the protrusion part 7f and each mounting leg 7a. The protrusion part 7f of the rib 7e is arranged offset from a straight line C, which connects the centers of through holes 7b of the respective mounting legs 7a continuous to the rib 7e, in the rotation axis direction X of the electric motor 5. The protrusion part 7f offset in the rotation axis direction X is arranged, for instance, within an existence range Wa of a connection portion of each mounting leg 7a continuous to the rib 7e to the housing and within ranges Wb, Wc of press fit portions of a compression mechanism 3 and the electric motor 5 to the housing.SELECTED DRAWING: Figure 1 【課題】車両に加わる外力から電動コンプレッサを確実に保護する。【解決手段】ハウジングの電動モータ５の回転方向に間隔をおいた箇所にそれぞれ形成された一対の取付脚７ａの間に、ハウジングと一体にリブ７ｅを突設した。このリブ７ｅは、先端７ｇがハウジングの外形よりも最も外側の位置に配置される突起部７ｆと、突起部７ｆと各取付脚７ａとの間をそれぞれ接続する一対の接続部７ｈとを有している。リブ７ｅの突起部７ｆは、リブ７ｅに連なる各取付脚７ａの貫通孔７ｂの中心間を結ぶ直線Ｃ上よりも電動モータ５の回転軸方向Ｘにオフセットして配置した。回転軸方向Ｘにオフセットさせた突起部７ｆは、例えば、リブ７ｅに連なる各取付脚７ａのハウジングに対する接続部分の存在範囲Ｗａ内で、かつ、ハウジングに対する圧縮機構３や電動モータ５の圧入部分の範囲Ｗｂ，Ｗｃ内に配置した。【選択図】図１
