PROBLEM TO BE SOLVED: To provide a heat insulating device for an actuator of a VG turbocharger of reduced cost and improved reliability by avoiding stress concentration and improving anti-vibration strength through reduction of the rigidity of a section where stress is high and facilitation of deformation. SOLUTION: In an L-shape thin plate stress reduction structure, one surface 52 of a plate member having an L-shape bent part is mounted on a vibration source member 4, the other surface 51 continuing from the one surface 52 includes a flange part 55 at one edge side in a lateral direction, a reinforcement piece 53 connecting a section near a bent side of the flange part 55 and a flange part 55 side end edge of the one surface 52 is arranged, and the other surface is arranged at an interval from the vibration source member 4. In projection quantity L from the bent part of the other surface 51 to the end edge of the other surface 51, a rigidity reduction part 56 where rigidity is reduced as compared with other sections is formed within a range of 3/1 or less of the projection quantity L from the bent part.
