[Detailed Description of the Invention] The present invention relates to a lever device such as a combination switch for an automobile, and its purpose is to provide a lever device that can improve manufacturability and assemblage and reduce weight.

An embodiment of the present invention will be described below with reference to the drawings. 1 and 2, reference numeral 1 denotes a lever base attached to the upper end of a steering pipe (not shown), a cylindrical part 2 (not shown) is formed in the center thereof, into which a steering shaft (not shown) is inserted; A shaft cylinder 3 is formed. Reference numeral 4 designates a synthetic resin bracket disposed on the lever base 1 so that it can be rotated in the direction of arrow L and the direction of arrow R (Fig. 2) about the shaft cylinder 3, as described below. A lever 5 for turn signal/damage/passing is rotatably mounted. The lever 5 is a well-known lever consisting of a lever body 6, a rotating rod 7 inserted into the lever body, and a knob 8 for operating the rotating rod by twisting the lever body 6 as shown by arrow A in FIG. Yes, the base end 6a of the lever body 6
, a moderation mechanism 9 is provided to moderate the rotation of the rotation rod 7 and thus the knob 8. moreover,
As shown in FIG. 3, the base end 6 of the lever body 6
In a, cylindrical case parts 12, 12 for housing the moderation steel ball 10 and spring 11 are integrally molded, and shaft parts 13, 13 are integrally molded on both sides of the base end part 6a. , furthermore, this shaft portion 13, 13
Protrusions 15, 15 are integrally molded at the tip portions of the protrusions 15, 15 through plate-shaped spacer portions 14, 14. The lower surfaces of the shaft portions 13, 13 and the upper surfaces of the protrusions 15, 15 have the same circular arc shape, and the lower surfaces of the protrusions 15, 15 are formed in an oblique shape. In addition, 7a is the rotating rod 7
The operator is integrally molded on the base end of the controller. Here, the bracket 4 includes, as shown in FIG.
A pair of walls 16, 16 are formed to accommodate the base end 6a portion of the lever body 6.
6 and 16, a moderation mechanism 1 is attached to the front end of the lever 5 with a steel ball 10 and a spring 11.
7 are formed, and stoppers 19, 19 are integrally molded in the upper part of the moderation recess 18 in the shape of a canopy, and the upper edge of the rear part of FIG. Concave fitting grooves 20, 20 for fitting and supporting the wall portions 16, 13 are integrally molded, and each fitting groove 20 of the wall portions 16, 16
On the outside of the portion, elastically deformable retaining portions 21, 21 are provided at a distance for arranging the spacer portion 14.
is integrally molded. This retaining portion 21 has a protrusion insertion hole 21 opposite to the fitting groove portion 20.
a is formed.

When attaching the lever 5 to the bracket 4, while inserting the case parts 12, 12 of the lever 5 below the stoppers 19, 19,
3 and 13 are secured to the retaining portion 2 by the protrusions 15 and 15.
1 and 21 while elastically deforming the fitting grooves 20 and 20.
Fits in. With this, the shaft parts 13, 13 are supported by the fitting groove parts 20, 20, and the spacer part 14
is interposed between the wall portion 16 and the retaining portion 21, so that the lever 5 is rotatably attached to the bracket 4 via the shaft portions 13, 13 in the directions of arrows B and C in FIG. ing. Therefore, the lever 5 is
As shown in the figure, when the bracket 4 is operated from the neutral position PN in the direction of the arrow L and the direction of the arrow R, it rotates together with the bracket 4, and in each direction, the well-known moderation mechanism 22 provided at the left end of the bracket 4 The left lane change instruction position PL' and the left turn instruction position PL
and a rightward lane change instruction position PR' and a right turn instruction position PR. Further, the lever 5 moves the moderation mechanism 1 to the low beam position HL in FIG. 1, the high beam position HU in the direction of arrow B, and the passing position HP in the direction of arrow C.
However, in the passing position HP, the lever 5 is in the low beer position HL.
will be automatically returned to. Further, when the knob 8 is twisted and rotated in the direction of arrow A, the moderation mechanism 9
It is held from the OFF position to the small lamp lighting instruction position, the head lamp lighting instruction position, and the parking lamp instruction position. In addition, in FIG. 1, 23 indicates the lever 5 in the arrow B direction and the arrow C direction.
a cam plate for a switch, which is moved left and right and front and back by the operation in the direction and the twisting operation of the knob 8;
4 is a switch section for light/parking and dema/passing which is operated by the movement of this switch cam plate 23, and 25 is a wiper lever;
6 is a cancel cam, and 27 (Fig. 2) is a cancel operating body. Although not shown, the lever base 1 is provided with a turn signal switch section and a wiper switch section.

Here, when operating the lever 5, there is a concern that the lever 5 may deviate beyond the moderation range of the moderation mechanism 17 if it is strongly rotated in the direction of arrow B. Since the stoppers 19, 19 prevent the case parts 12, 12 of the lever 5 from rotating as shown by the two-dot chain line in FIG. 5, there is no such concern. Also, the lever 5 moves the moderation mechanism 1 in the direction of arrow C.
If the bracket 4 is rotated beyond the moderation range 7, the rotation is prevented by the bottom wall portion 4a (FIG. 5) which is continuous with the lower end of the moderation recess 18 of the bracket 4. At this time, the shaft parts 13, 13 of the lever 5 are connected to the fitting groove part 20,
There is a concern that the device may be removed from the device 20, but this is prevented by the retaining portions 21, 21.

By the way, in the lever device of this type of lever combination switch, an end plate made of a steel plate is attached like a lid to the upper part of the wall part 16, and the end plate prevents the lever 5 from rotating in the direction of arrow B. 13 is also prevented from coming off, but in this case, the end plate must be formed separately from the bracket 4, and the work of attaching the end plate itself is also required.
It had the drawbacks of poor manufacturability and assembly, and increased weight.

In this regard, according to this embodiment, the stopper part 19 and the retaining part 21 are integrally molded on the synthetic resin bracket 4, so the conventional end plate made of steel plate can be made unnecessary, and the stopper part 19 and Since the retaining portion 21 can be obtained together with the molding of the bracket 4, the number of manufacturing steps will not increase.

Furthermore, according to this embodiment, the shaft portion 13 is supported by the fitting groove portion 20 instead of the elastically deformable retaining portion 21, so that the shaft portion 13 can be supported reliably. In other words, in the case of a configuration in which the shaft is supported and prevented from coming out only by the hole in the elastically deformable retaining part, there is a possibility that the shaft may be inadvertently fitted during assembly, such as fitting the shaft into the hole, or when operating the lever. When a strong external force is applied to the shaft portion from above, the shaft portion presses the hole in the retaining portion, causing the retaining portion to be elastically deformed, and the shaft portion may come off from the hole. However, in this embodiment, the shaft portion 13 is supported not by the elastically deformable retaining portion 21 but by the fitting groove portion 20 formed in the wall portion 16 that is not expected to undergo elastic deformation, so that a strong force is applied to the shaft portion 13 from above. Even if it is, the wall part 1 that supports this
6 is not likely to be elastically deformed, and therefore the shaft portion 1
3 will not come off from the fitting groove 20 and the protrusion insertion hole 21a.

Furthermore, according to this embodiment, since the spacer part 14 integrated with the shaft part 13 is located between the wall part 16 and the retaining part 21, even if a large force is applied to the lever 5 in the axial direction, The shaft portion 13 does not move in the axial direction, and in general, the shaft portion 13 will not come off from the fitting groove portion 20 even if a force is applied in any direction.

As is clear from the above description, the present invention integrally molds a stopper part and a retaining part on a synthetic resin bracket, thereby making it possible to eliminate the need for a conventional end plate made of a steel plate. Since the part and the retaining part can be obtained together with the bracket when molding the bracket, there is no increase in manufacturing man-hours, and when installing the lever, the shaft part can be fitted into the fitting groove part. This can be done with extremely simple work, and the overall manufacturability and assemblability can be greatly improved, and the weight can also be reduced.

Furthermore, the shaft is supported by the fitting groove formed in the wall, and the spacer part, which is integrated with the shaft, is positioned between the wall and the retaining part, ensuring that the shaft does not come off. can be prevented.
