PROBLEM TO BE SOLVED: To solve a problem that a large throttled resistance is applied on an exhaust gas auxiliary stream passing through a bypass and the exhaust gas auxiliary stream is prevented from flowing out of a waist gate valve port. SOLUTION: A connector for exhaust gas discharging of an engine supercharger is provided with an elbow passage 1 and the bypass 2. The bypass 2 is located at the side of the elbow side 1. An inner end inner wall surface 8 of the bypass 2 is retreated from a bypass inlet 7 to the separating direction. An elbow passage 1 side of the bypass 2 is opened for the elbow passage 1 from the bypass inlet 7 as far as an innermost end inner wall surface 9. The innermost end inner wall surface 9 of the bypass 2 is retreated beyond a lower part extended axis 5b of an outlet center axis 5a. A passage sectional area of the bypass 2 is so large that the throttled resistance applied on the auxiliary stream 15 passing through the bypass 2 out of the waist gate valve port 6 is lessened.
