PURPOSE:To facilitate an adjustment work by constituting the titled adjuster so that a tuning unit is locked with an adjusting spindle to move at the time of putting in/out of said unit, and releasing the lock at the time of not adjusting. CONSTITUTION:A connecting member 4 is inserted between the upper unit 21 and the lower unit 22 of a displacement member 2, and after thus integrating the two units, the member 4 is lowered until it covers the foremost end of the adjusting spindle 5. Then a hexagonal wrench is inserted in the hole 44 of the connecting member 4 and turned clockwise to let a vertical groove 41 provided in the member 4 and a protrusion 51 formed on the spindle 5 engage with each other, and at this time, the protrusion 43 of the connecting member 4 engages in the vertical groove 26 provided in the displacement member 2, thereafter, the member 4 is further turned clockwise so that the protrusion 51 of the spindle 5 engages in the lateral groove 42 of the connecting member, while the protrusion 43 of the connecting member engages in the lateral groove 27 of the displacement member. Being in this state, the adjusting spindle 5 is coupled with the member 2 by the connecting member 4. In such a way, the adjustment work is facilitated. |
