The sliding members 26 are each slidably held. In this case, the upper end of the contact holder 22 is engaged with the U-shaped groove 11 of the first actuating member 12 that is integrated with the bracket 3, so that when the bracket 3 rotates around the fulcrum shaft 4, the U-shaped groove 11
Through engagement with the groove 11, it is moved in a direction perpendicular to the plane of the paper in FIG. 2 (vertical direction in FIG. 1). This contact holder 22
The above-mentioned movement causes the direction indicator switch 21 to switch, and as a result, the direction indicator switch 21 issues a right turn instruction when the operating lever 7 is rotated from the neutral position PN to the right turn instruction position PR. The left turn instruction lamp is turned on, and when the left turn instruction position PL is rotated, the left turn instruction lamp is turned on. On the other hand, the first sliding member 24 is held by the holding frame 19 so as to be able to slide left and right in FIG. The engagement groove 27 that engages with the fulcrum shaft 4 is formed in a substantially arc shape centered on the fulcrum shaft 4. This first sliding member 24 is for operating the passing/dimmer changeover switch 23, and when the operating lever 7 is rotated around the support shaft 8 in the clockwise and counterclockwise directions in FIG. , the first sliding member 24 is slid to the left and right in FIG.

It is fixed to the front surface of the bracket 3 by screws 44, 44 which are screwed into the brackets 3, 43. In this way, the support shafts 8, 8 of the operating lever 7 are prevented from coming off from the bearing recesses 8a, 8a of the bracket 3 by the holding pieces 9a, 9a of the metal fitting 9. In the present invention, the operating lever held in a pivoted state by the holder (metal fitting) attached to the bracket as described above is of course not limited to the one for switching between passing and demagnetizing. It is.

As understood from the embodiments described in detail above, the present invention includes forming a cam surface on a plastic bracket that rotatably supports the operating lever to provide a force for holding the operating lever in a fixed position. A die-cut hole is formed along with the integral molding of the cam surface, and a holder is fixed to the bracket, at least a portion of which is engaged and held in the die-cut hole to hold the operating lever in a pivotally supported state. It has the following characteristics and can be expected to have the following effects. That is,
Conventionally, the cam surface that forms a part of the moderation mechanism that holds the operating lever for switching between passing and damping in a fixed position was formed from a metal plate, and the structure was such that this was attached to the bracket with screws. In the present invention, since the cam surface is formed integrally with the bracket, it is possible to eliminate the need for machining, forming, and screwing a metal plate for forming the cam surface. Furthermore, the holder that holds the operating lever in a pivotally supported state that cannot be removed from the bracket is attached to the bracket by engaging and holding at least a portion of it in a punched hole formed in the bracket when the cam surface is integrally molded. Because of this structure, the number of screws required for attaching the holder to the bracket can also be reduced.

Furthermore, since the cam surfaces constituting the moderation mechanism are formed on both sides of the axis perpendicular to the rotating axis of the bracket, the moderation mechanism portion on the operation lever side is also distributed on both sides, and therefore the moderation movement direction of the operation lever is Since the balance regarding rotation is improved, the operability is improved, and as a result of such dispersion, the necessary moderating engagement force can be secured without causing local enlargement.
