エータ（９）の作動点を調整するようになされている。Since the boost pressure control device for a conventional engine is configured as described above, the exhaust gas discharged from the engine cylinder (not shown) passes through the exhaust gas inlet (6) and reaches the exhaust gas outlet (7) K. When flowing out, this exhaust gas causes the turbine (3) of the supercharger (1) to rotate at high speed, so the compressor (2) directly connected to this turbine (3) via a connecting shaft (1 person) also rotates at high speed. , air supply inlet passage (4)
The intake air flowing in is compressed and sent under pressure to the engine through the supercharging air passage φ). When the engine speed increases, the amount of exhaust gas inevitably increases, which increases the rotation of the turbine (3) and increases the pressure added to the compressor (2), which improves the efficiency of the engine. being done. There is an upper limit to the boost pressure from the supercharger (1) K depending on the engine characteristics, and in order to operate at an appropriate boost pressure, the waste gate actuator (9) that responds to the boost pressure is used to pump waste gate pulp (8). The operating point of the wastegate actuator (9) is adjusted so that the wastegate actuator (9) operates at a supercharging pressure higher than the upper limit of the supercharging pressure.

しまうとい５欠点がある。This adjustment is done by adjusting the degree of screw engagement between the threaded hole (94,) of the adjustment rod shaft and the threaded part (92,) of the connecting rod screwed into the hole (94,), as shown in Figure 2. It is being done. However, with the conventional adjustment means described above, car enthusiasts who want to increase only the output while ignoring engine performance can readjust it freely by loosening the lock nut and rotating the adjustment load shaft. There are 5 drawbacks to being able to do this.

The connecting part between the connecting rod (a) and the adjusting rod is shown, and the ring shows the connecting position of the adjusting rod and the connecting rod (a) so that the opening of the waste gate pulp (8) is suitable for the engine performance. After adjusting the adjustment position, a cylindrical protective sleeve is inserted to cover the lock nut that locks the adjusted position.The protective sleeve member hides the lock nut (to) and then uses crimping pliers, etc. A part of the protective sleeve (a) is constricted by a tool to form a constriction part (96,) and fixed in a predetermined position.
It is constructed in such a way that it cannot be easily moved without tearing it off.

ことはいうまでもない。As described above, the present invention hides the lock nut (on the connecting rod of the waste gate actuator (9)) and the lock nut (on the connecting rod) of the waste gate pulp (8) with the protective sleeve (). , and because it is fixed, once the manufacturer has adjusted it to the ideal condition, it has an excellent effect that cannot be readjusted easily unless the protective sleeve ring is torn off. It is something. In addition, when the protective sleeve is fixed by tightening it, it is required to legally seal it by stamping a mark on the tightened portion (96,) with a press. It can also be done easily. Furthermore, the shape of the protective sleeve is not limited to the cylindrical shape described above (it goes without saying that a polygonal cylindrical shape can also provide the same effect).
