置。A shaft 8 has one end attached to the exhaust bypass valve 5 that opens and closes the exhaust bypass passage 6, a diaphragm 9 attached to the other end of the shaft 8, and the diaphragm 9 connects the inside to the pressure chamber 10a and the atmosphere. No. 1 housing 10 separated into a chamber 10b etc., and the housing 1
A state in which the exhaust bypass valve 5 is closed when the communication passage 11 connecting the zero pressure chamber 10a and the intake manifold 4 and the boost pressure acting on the pressure chamber 10a through the communication passage 11 are below a set value. When the boost pressure exceeds a set value, the diaphragm 9 and shaft 8 are actuated to open the exhaust bypass valve 5, and a part of the exhaust gas is removed. In the exhaust bypass control device for a turbocharger that maintains the supercharging pressure below a set value by bypassing the turbine 2, the housing 10 includes a low friction material 19 such as a fluororesin, and a low friction material 19 such as a fluororesin. Attach a guide bushing 18 consisting of a cylindrical elastic material 20 with a material 19 attached to the inner peripheral surface,
An exhaust bypass control device for a turbocharger, characterized in that the shaft 8 is inserted into the guide bush 18.
