PROBLEM TO BE SOLVED: To provide a centrifugal compressor capable of suppressing occurrence of surging, and a turbocharger.SOLUTION: By closing a communication hole 60 with a closing member 66, backflowing force acting on compressed air having passed through a winding start part 54A on the side of a winding end part 54B is weakened. Consequently, when the closing member 66 is arranged at a closing position, occurrence of backflow is suppressed, and then occurrence of surging is suppressed.SELECTED DRAWING: Figure 2 【課題】遠心圧縮機において、サージングが発生するのを抑制することができる遠心圧縮機、及びターボチャージャを得る。【解決手段】閉止部材６６で連通孔６０を閉止することで、巻き終わり部５４Ｂ側で巻き始め部５４Ａを通過した圧縮空気に作用する逆流する力は弱まる。これにより、閉止部材６６が閉止位置に配置されている場合には、逆流の発生が抑制され、サージングの発生が抑制される。【選択図】図２
