  In the above-described conventional configuration, the light slider 23 is assembled by placing the slider 23 on the upper surface of the slider guide portion 24 of the insulator 2, and then assembling the intermediate case 3 from the slider 23. A structure is adopted that is sandwiched between the three restricting portions 3a from the height direction. In other words, since the height direction of the slider 23 is regulated by two parts of the insulator 2 and the intermediate case 3, the clearance in the height direction is likely to vary due to the tolerance of these two parts, and is a switch element. There is a problem that the operation of the light switch 25 tends to become unstable. Further, since the slider 23 has to be sandwiched between two parts of the insulator 2 and the intermediate case 3, there is a problem that the assembling property is poor.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a vehicle lever switch device that can reduce variations in the clearance in the height direction of the slider and improve the assemblability.

  In order to achieve the above object, a vehicle lever switch device according to the present invention is provided with an insulator, a case assembled to an upper portion of the insulator, a slider slidably disposed on an upper surface of the insulator, and the insulator. A slider guide portion having a cylindrical portion that regulates the upward movement of the slider and guides the sliding movement of the slider, and is provided so as to extend in the axial direction and rotate around the axis. A lever that slides the slider in accordance with a turning operation in the direction around the axis, and a switch element that switches a state in accordance with the sliding movement of the slider are provided.

  According to the above-described means, since the slider is assembled by being inserted into the cylindrical portion of the slide guide portion provided in the insulator, the assemblability can be improved as compared with the structure in which the slider is sandwiched between two parts. Further, since the clearance in the height direction of the slider can be managed by one part of the insulator, the variation can be reduced as compared with the case of managing by two parts.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
The unit case 31 includes an insulator 32 and a case 33 that has a ceiling portion 33 a and is assembled to the upper portion of the insulator 32. A turn bracket 34 is disposed in the unit case 31. The bracket 34 is attached to the unit case 31 so as to be rotatable about the shaft portion 35 in the direction of the arrow B1 in FIGS.

This detent plate 37 is provided with moderation uneven portions 38 for turning and for dimmer passing.

  One end portion of an operation lever 39 is inserted into the bracket 34, and the one end portion is attached to the bracket 34 via a shaft portion 40. The operation lever 39 is rotatable in the direction of arrow B2 in FIG. 3 with the shaft portion 40 as a fulcrum. The other end (right end in FIG. 1) of the operation lever 39 protrudes outward from the unit case 31 and the bracket 34. A moderation piece 41 and a moderation spring 42 for urging the moderation piece 41 are provided at the tip of one end of the bracket 34, and the tip of the moderation piece 41 abuts on the moderation uneven portion 38 of the detent plate 37. ing. Here, the moderation mechanism 43 is configured by the moderation uneven portion 38 of the detent plate 37, the moderation piece 41, and the moderation spring 42.

  In this case, when the operation lever 39 is rotated in the direction of the arrow B1, the operation lever 39 and the bracket 34 are integrally rotated about the shaft portion 35 in the direction of the arrow B1. At this time, a moderation feeling is given by the moderation mechanism 43. When the operation lever 39 is rotated in the direction of arrow B2, the operation lever 39 is rotated in the direction of arrow B2 with the shaft portion 40 as a fulcrum, leaving the bracket 34. At this time, a moderation feeling is given by the moderation mechanism 43.

  A dimmer / passing slider 45 is disposed substantially at the center of the upper surface of the insulator 32. A guide convex portion 46 extending in the left-right direction in FIG. 1 is provided near one side portion of the upper surface of the insulator 32. The slider 45 is provided so as to be slidable along the guide projection 46 in the direction of the arrow B3 in FIGS. The slider 45 has a plurality of cam portions 48 on the lower surface and a pair of walls 49a forming an arcuate groove portion 49 having an upper surface opened on the upper portion. An arm holder 50 is attached to the tip of one end of the operation lever 39, and a convex portion 51 of the arm holder 50 is inserted into the groove 49.

The upper end portion of the push rod 60 is in a state where it can project through the hole formed in the insulator 32 to the upper surface side of the insulator 32. The fixed contact 57 and the movable element 58 constitute a dimmer / passing switch 61.

  Here, when the operation lever 39 is rotated in the direction of the arrow B1 about the shaft portion 35 of the bracket 34, the operation lever 39 and the bracket 34 are integrally rotated in the direction of the arrow B1. With the rotation, the state of the turn switch 55 is switched. At this time, the convex portion 51 of the arm holder 50 is also rotated in the same direction. However, the convex portion 51 moves along the groove portion 49 that forms the arc shape of the slider 45, so the slider 45 does not move.

  Further, when the operation lever 39 is rotated in the arrow B2 direction with respect to the bracket 34, the slider 45 is slid in the arrow B3 direction via the arm holder 50, and the cam portion 48 of the slider 45 causes the push rod 60 to pass through the push rod 60.

The slider guide portion 66 is provided with a cylindrical portion 67 extending in the arrow B5 direction substantially orthogonal to the arrow B3 direction, which is the moving direction of the slider 45, and two claw portions for preventing detachment. 68 is provided. The cylindrical portion 67 is formed by a slide mold at the time of molding. Then, by inserting a part of the slider 65 into the cylindrical portion 67, the upward movement is regulated and the sliding movement in the direction of the arrow B5 is guided. Further, the upward movement of the slider 65 is also restricted by the claw portion 68.

  The slider 65 has a plurality of cam portions 69 on the lower surface and a pair of walls 70 a forming a groove portion 70 on the upper portion, and the operation convex portion 64 of the light lever 62 is inserted into the groove portion 70. ing. On the lower surface side of the insulator 32, a light switch (corresponding to the switch element of the present invention) 71 having the same configuration as the above-described dimmer / passing switch 61 is provided below the slider 65. The light switch 71 includes a fixed contact 72 provided on the lower surface of the insulator 32, and a movable element 75 having a contact portion 73 and a push rod 74. The upper end of the push rod 74 is formed on the insulator 32. It is in a state where it can protrude through the hole to the upper surface side of the insulator 32. Between the operation lever 39 and the light knob 63, a moderation ball 77 and a moderation spring 78 constituting a moderation mechanism 76 for light are disposed.

  Here, when the light lever 62 is rotated by the light knob 63 in the direction of the arrow B4, the slider 65 slides in the direction of the arrow B5 via the operation convex portion 64, and accordingly the state of the light switch 71 is changed. Is switched.

  A lower cover 79 is attached to the lower side of the insulator 32. Further, on the upper surface of the bracket 34, a cancel mechanism 82 including a ratchet 80, a back plate 81, and the like is provided. The cancel mechanism 82 is based on the fact that a cancel cam (not shown) is rotated in accordance with the rotation of a steering wheel (not shown) in a state where the operation lever 39 and the bracket 34 are positioned at a left turn instruction position or a right turn instruction position during a turn operation. The operation lever 39 and the bracket 34 are automatically returned to the neutral position.

  In the embodiment described above, the following operational effects can be obtained. That is, since the light slider 65 is assembled by being inserted into the cylindrical portion 67 of the slide guide portion 66 provided in the insulator 32, the assemblability can be improved as compared with the structure in which the slider is sandwiched between two parts. Further, since the clearance in the height direction of the slider 65 can be managed by one component of the insulator 32, variation can be reduced as compared with the case of managing by two components. Further, since it is not necessary to press the slider 65 with the case 33, the intermediate case which has been conventionally required can be made unnecessary, and the unit case 31 is composed of two parts, the insulator 32 and the case 33 assembled to the upper part thereof. Can do.

The present invention is not limited to the above-described embodiment, and can be modified or expanded as follows.
The slider 65 can be configured by a contact holder having a movable contact instead of the one having the cam portion 69. In this case, the light switch as the switch element is composed of a fixed contact provided on the upper surface of the insulator 32 and a movable contact that contacts and separates from the fixed contact as the contact holder slides.
