であり、十分に満足な結果は得られない。 In internal combustion engines, ignition timing has a large effect on engine performance, and especially when ignition timing is strictly adjusted to prevent engine exhaust gases, it is important for the user to change the ignition timing without permission. This results in a loss of effectiveness. For this reason, it is desirable that the power distribution device of the ignition system be attached to the engine body in such a way that it cannot be adjusted by the user.
As a fixing means for this purpose, JP-A-54-
There is one described in Publication No. 113751. This known fixing means separates the screw head from the screw body when the screw is tightened with a tightening torque exceeding a predetermined value.
Use a tightening screw that cannot be tightened or loosened any further, and in the tightened state,
By providing a wall that covers the head of the screw body, the screw cannot be loosened by applying an impact force to the side surface of the head of the screw body. but,
Even if this kind of fixing means is used for installation, it is possible to change the mounting position of the distributor body by tapping the mounting part of the distributor body from the side, and a fully satisfactory result may not be obtained. do not have.

A first inclined surface inclined in the direction opposite to the first inclined surface and a second inclined surface inclined in the opposite direction to the first inclined surface are formed, and is attached to the elongated hole at a position corresponding to each of the first and second inclined surfaces. A screw is inserted, and a washer member whose thickness changes at an angle that matches the inclination angle of the inclined surface is disposed between the mounting screw and the mounting portion of the power distributor. According to the present invention, two inclined surfaces with opposite inclination directions are provided along the arc-shaped elongated hole provided in the mounting portion of the power distribution device, and the mounting screw is inserted into the elongated hole at a position corresponding to the inclined surfaces. Since it is inserted, it becomes impossible to change the mounting position by hitting the mounting portion of the power distributor after tightening the mounting screw. The number of arc-shaped elongated holes is not limited to one, but two or more may be provided, and a first inclined surface may be formed along one elongated hole and a second inclined surface may be formed along the other elongated hole.
In addition, in order to prevent the mounting screw from being removed after tightening, use a mounting screw whose head is separated from the screw body when the screw is tightened with a tightening torque exceeding a specified value. The washer member may be provided with a peripheral wall surrounding the head of the screw body.

A mounting plate 2 is fixed to the lower surface of a main body 1 of a power distributor with bolts 3, and the main body 1 of the power distributor is attached to an engine main body 4 by the mounting plate 2. As shown in FIG. 2, arc-shaped elongated holes 6 and 7 having their centers on the central axis 5 of the power distributor are formed in the mounting plate 2, and mounting screws 8 and 9 are inserted into these elongated holes 6 and 7. be done. Along the elongated hole 6, a first inclined surface 10 inclined in the length direction of the elongated hole 6 is formed on the upper surface of the mounting plate 2, and similarly along the elongated hole 7, a first inclined surface 10 is formed in the opposite direction to the first inclined surface 10. A second inclined surface 11 is formed. The mounting screw 8 consists of a screw body 8b having a head 8a and a head 8d coupled to the head 8a of the screw body 8b via a constriction 8c. Below the head 8a of the screw body 8b, a washer member 12 is located. The washer member 12 has a lower surface inclined at an angle corresponding to the inclination of the first inclined surface 10, a flat upper surface, and a peripheral wall 12a surrounding the head 8a of the screw body 8b. When installing the power distributor main body 1, after adjusting the position along the elongated holes 6 and 7, the head 8d
When the mounting screw 8 is tightened by operating the , when the tightening torque exceeds a predetermined value, the head 8d is torn off at the constriction 8c, resulting in the state shown in FIG. 3. The mounting screws 9 are similarly configured, and in this state, it is impossible to remove the mounting screws 8 and 9 without breaking the washer member 12.
After tightening, even if the mounting plate 2 is hit from the side, its position will not change due to the presence of the inclined surfaces 10 and 11 in opposite directions.
