Claims

[Claims for Utility Model Registration] (1) The turbocharger has a ring that rotates concentrically with the turbine shaft while being guided by a guide part provided on the outer wall of the center housing of the turbocharger, and a guide groove formed in the ring has a ring that rotates concentrically with the turbine shaft. In a turbocharger with a variable nozzle that converts rotation of the ring into rotation of the variable nozzle and changes the angle of the variable nozzle by slidably engaging a pin fixed to a lever attached to the shaft of the variable nozzle, A turbocharger with a variable nozzle, characterized in that contact prevention means for preventing contact between the parallel surfaces of the ring and the lever is provided near the pin. (2) Practical use in which the contact prevention means is constituted by a cylindrical raised portion protruding toward the ring side, which is formed on the ring side periphery of the hole for fixing the pin formed in the lever. A turbocharger with a variable nozzle as claimed in claim 1. (3) The contact prevention means is constituted by a partially spherical raised portion protruding toward the ring side, which is formed on the ring side periphery of the hole for fixing the pin formed in the lever. A turbocharger with a variable nozzle according to claim 1 of the registered utility model. (4) The turbocharger with a variable nozzle according to claim 1, wherein the contact prevention means is constituted by a washer interposed between the lever and the ring and having a center hole through which the pin is inserted.
