A flasher switch circuit 22 that is switched in conjunction is provided. The flasher switch circuit 22 is for selectively blinking one of left and right flasher lamps (not shown).

  By the way, as shown in FIGS. 1, 2, and 4, the base portion 2B that rotates together with the grip portion 2A is provided inside the grip portion 2A of the first rotary knob 2. An operation knob 4 is guided and fitted to the outer periphery of a cylindrical portion 2c erected vertically to the center of the portion 2B so as to be movable up and down. A cylindrical bellows-shaped waterproof member 23 is disposed in a space defined by the grip portion 2A and the base portion 2B of the first rotary knob 2, and the inner peripheral portion of the upper end of the waterproof member 23 is an operation knob. 4 is fitted in a concave groove 4a formed on the outer periphery of 4.

  Further, the flange 23a formed on the outer periphery of the lower end of the waterproof member 23 is placed on the inner bottom surface of the base portion 2B, and is formed in a cylindrical shape formed vertically downward from the inner surface of the upper wall of the first rotary knob 2. It is sandwiched between the pressing rib 2d and the base portion 2B. Therefore, the operation knob 4 is configured to protrude from the insertion hole 2b of the grip portion 2A even when the operation knob 4 is not fitted to the operation rod 7 by the urging force of the waterproof member 23. The upper flange portion 4B is made larger in diameter than the lower side so as to be substantially flush with the flange portion 4B when the inner peripheral portion of the upper end of the waterproof member 23 is fitted in the concave groove 4a of the operation knob 4. Is preferred. With such a configuration, it is possible to prevent the inner peripheral portion of the upper end of the waterproof member 23 from coming off the concave groove 4a even when water pressure is applied by high-pressure cleaning.

  Thus, the first rotor 5 is inserted and fitted into the cylindrical portion 2c of the base portion 2B of the first rotary knob 2, and the operation knob 4 moves up and down as described above on the outer periphery of the upper end portion thereof. It is possible to fit. As a result, the fitting portion is covered and sealed by the waterproof member 23, so that water that has entered from the gap between the operation knob 4 and the insertion hole 2b cannot reach the fitting portion, and the operation rod 7 penetrates further. The rod insertion hole 5c of the first rotor 5 that is in contact cannot be reached. For this reason, water enters the fitting portion between the first rotor 5 and the cylindrical portion 2c of the base portion 2B of the first rotary knob 2 and the rod insertion hole 5c through which the operation rod 7 of the first rotor 5 passes. Can be prevented. Thereby, since it is not necessary to interpose a sealing member such as an O-ring between the operation rod 7 and the rod insertion hole 5c, high waterproofness can be achieved without deteriorating the operability of the operation knob 4. it can. In FIG. 1, reference numeral 24 denotes the first rotor 5 and the second rotor 6, the first rotor 5 and the through hole 2 a of the base portion 2 </ b> B of the first rotary knob 2, the switch body 8, and the second rotor 6. This is an O-ring as a seal member for further preventing water from entering from the fitting portion.

It is attached to the outer periphery of the upper end portion of the first rotor 5 through a through hole 2a of the knob 2 (base portion 2B).

  By the way, in the present embodiment, as shown in FIGS. 2 and 3, there are two hole portions 2e, 2e, 2b in the circumferential direction opposite to each other between the pressing rib 2d formed on the first rotary knob 2 and the base portion 2B. 2f is formed, and an engaging claw-shaped protrusion 2g is formed above the hole 2f of the base portion 2B. Then, the two protrusions 2g are respectively fitted into the two holes 2e of the pressing rib 2d, whereby the base portion 2B constituting the first rotary knob 2 is coupled and integrated with the grip portion 2A. Then, the two protrusions 2g are respectively fitted into the two holes 2e of the pressing rib 2d, whereby the base portion 2B constituting the first rotary knob 2 is coupled and integrated with the grip portion 2A. As shown in the figure, a gap δ is formed by connecting the hole 2f formed to be connected to the protrusions 2g engaged with each other and the holes 2e. . In other words, the base portion 2B and the grip portion 2A constituting the first rotary knob 2 are infiltrated into the first rotary knob 2 using the holes 2e and 2f formed to be integrally fitted. It forms a drainage channel for draining water.

  In the present embodiment, the protrusion 2g is formed on the base 2B side. However, the protrusion 2d is formed on the pressing rib 2d side, and the protrusion 2g is fitted in the hole 2f on the base 2B side. May be adopted. Further, a concave drainage groove communicating from the bellows part to the tip of the collar part 23a is formed in a part of the collar part 23a formed on the outer periphery of the lower end of the waterproof member 23, or a part of the cylindrical pressing rib 2d is drained. A notch may be formed. If comprised in this way, even if it is pinched | interposed by the cylindrical press rib 2d and the base part 2B, the water deposited on the collar part 23a can also be discharged | emitted. Furthermore, it is preferable to set the inclination angle so that water attached to the inclined surface of the protrusion 2g flows toward the hole 2f.

  Next, the configuration of the first and second rotors 5 and 6 will be described.

  As shown in FIG. 1, the first rotor 5 and the second rotor 6 are arranged so as to be relatively coaxially rotatable outside the slide base 11, and the first rotor 5 is as shown in FIG. 11. Further, it is composed of a cylindrical shaft cylinder portion 5A extending in the vertical direction and a crank-shaped arm portion 5B formed at the lower end of the shaft cylinder portion 5A. An operating rod passage hole 5c through which is inserted is formed (see FIG. 1).

  A plurality of corrugated engagement grooves 5 a are formed on the upper surface of the arm portion 5 B of the first rotor 5, and a pin 5 b projects integrally downward on the lower surface. As shown in FIG. 1, the arm portion 5B of the first rotor 5 is accommodated in the switch body 8, and one of the engaging grooves 5a formed in the arm portion 5B is biased by a spring 25. The steel ball 26 is engaged. Here, the engaging groove 5a, the steel ball 26 engaged with the engaging groove 5a, and the spring 25 for urging the steel ball 26 constitute a click mechanism. A feeling is given.

  Also, as shown in FIG. 5, the pin 5b formed on the arm portion 5B of the first rotor 5 passes through the opening 11b formed in the slide base 11 shown in FIG. This pin 5b is engaged between a pair of guide ribs 14a provided in parallel with the upper surface of the first slide member 14 accommodated in the slide base 11. As a result, the rotation of the first rotor 5 operated by the first rotation knob 2 is converted into linear sliding of the first slide member 14 in the direction perpendicular to the axis.

  On the other hand, as shown in FIG. 12, the second rotor 6 includes a cylindrical portion 6A extending in the vertical direction and a crank-shaped arm portion 6B formed at the lower end of the cylindrical portion 6A. Here, the cylindrical portion 6A of the second rotor 6 has a larger diameter than the shaft cylinder portion 5A of the first rotor 5, and the second rotor 6 is inserted into the first rotor 5 by inserting the first rotor 5 therein. It is rotatably supported by the shaft cylinder portion 5A of the first rotor 5 (see FIG. 1).

  A plurality of corrugated engagement grooves 6a are formed on the upper surface of the arm portion 6B of the second rotor 6, and a pin 6b is integrally projected downward on the lower surface. As shown in FIG. 1, the arm portion 6B of the second rotor 6 is accommodated in the switch body 8, and one of the engaging grooves 6a formed in the arm portion 8B is biased by a spring 27. The steel ball 28 is engaged. Here, the engaging groove 6a, the steel ball 28 engaging with the engaging groove 6a, and the spring 27 for urging the steel ball 28 constitute a click mechanism, and the click mechanism is clicked to rotate the second rotary knob 3. A feeling is given.

  Further, as shown in FIG. 6, the pin 6b formed in the arm portion 6B of the second rotor 6 passes through the opening 11b formed in the slide base 11 shown in FIG. This pin 6 b is engaged between a pair of guide ribs 15 a erected in parallel to the upper surface of the second slide member 15 accommodated inside the slide base 11. As a result, the rotation of the second rotor 6 operated by the second rotary knob 3 is converted into a linear sliding of the second slide member 15 in the direction perpendicular to the axis. That is, in the switch device 1 according to the present embodiment, the light switch circuit 20 and the flasher switch circuit 22 are disposed on the opposite surfaces of the first and second base members 12 and 13 to the push switch mechanism, The first rotary knob 2 and the second rotary knob 3 constitute a switch mechanism by a slide switch mechanism that linearly slides in an orthogonal direction. Therefore, the space formed by the hazard switch circuit 21 is used rather than providing the rotary switch mechanism by the first rotary knob 2 and the rotary switch mechanism by the second rotary knob 3 in the plane direction of the switch body 8. Therefore, the arrangement surface of the light switch circuit 20 and the flasher switch circuit 22 can be formed efficiently. Therefore, since a plurality of switch circuits can be arranged in an integrated manner, the switch body 8 can be reduced in size.

  As shown in FIG. 1, a mounting nut 29 is screwed onto the outer periphery of a cylindrical portion 8 a erected on the top of the switch body 8, and the switch device 1 is tightened by tightening the mounting nut 29. Can be attached to a predetermined location.

  Next, the operation of the switch device 1 configured as described above will be described.

  The switch device 1 according to the present embodiment has a hazard switch function, a light switch function, and a flasher switch function as described above. For example, in order to blink the hazard lamp, the operation knob 4 is pushed only once. . Then, the pushing of the operation knob 4 is transmitted to the slider 9 through the operation rod 7, and the slider 9 slides downward against the urging force of the spring 16, and the operation knob 4, the operation rod 7 and the slider are moved. 9 is held at that position by the cam mechanism, and a flasher terminal 19 provided on the slider 9 (see FIGS. 7A and 7B) is provided on the inner surface of the second base member 13. And the hazard lamp blinks.

  When the operation knob 4 is pushed in again from the above state, the operation knob 4, the operation rod 7 and the slider 9 are moved up by the urging force of the spring 16 by the action of the cam mechanism and returned to the original position shown in FIG. Therefore, the continuity between the flasher terminal 19 provided on the slider 9 and the flasher switch circuit 22 provided on the inner surface of the second base member 15 is cut off, and the blinking of the hazard lamp is stopped.

  Further, when the first rotation knob 2 is turned, the first rotor 5 rotates integrally, and the rotation thereof is in the direction perpendicular to the axis of the first slide member 14 (in the direction perpendicular to the plane of FIG. 1) as described above. Since the first slide member 14 is slid, the light switch circuit 20 provided on the outer surface of the first base member 12 is switched, and the headlamp is turned on / off as described above. Switching between OFF, Hi beam, and Lo beam is performed. That is, when the first rotary knob 2 is in the OFF position shown in FIG. 13, the headlamp is turned off, and the first rotary knob 2 is moved clockwise from the OFF position to the angle α shown in FIG. 13 (in the present embodiment). When the headlamp is turned by 30 °, the headlamp is switched to the Lo beam, and from there, the headlamp is switched to the Hi beam by further turning clockwise by the angle α. As described above, a click feeling is given to the rotation of the first rotary knob 2 by the click mechanism.

  On the other hand, when the second rotation knob 3 is turned, the second rotor 6 rotates integrally with the shaft cylinder portion 5A of the first rotor 5 as the center, and the rotation is performed by the second slide member 15 as described above. Therefore, the flasher switch circuit 22 provided on the outer surface of the second base member 15 is switched by the sliding of the second slide member 15. The flashing of the left and right flasher lamps is switched. That is, when the second rotary knob 3 is turned clockwise from the neutral position N by an angle β shown in FIG. 13 (20 ° in this embodiment) to the R position, the right flasher lamp blinks and the angle from the neutral position N is increased. When it is turned counterclockwise by β to the L position, the left flasher lamp blinks. As described above, a click feeling is also given to the rotation of the second rotary knob 3 by the click mechanism.

  As described above, in this embodiment, the operation knob 4, the first rotation knob 2, and the waterproof member 23 constitute the operation unit 30, and the operation unit 30 is connected to the first rotation knob 2 through the through hole 2 a. Since it is attached to the outer periphery of the upper end of the first rotor 5, it is possible to reliably prevent water from entering the gap between the first rotor 5 and the operation unit body 30 from the gap between the operation knob 4 and the insertion hole 2b.

  Further, in the present embodiment, the shaft portion is composed of the first and second rotors 5 and 6 that are rotating shaft portions and the operation rod 7 that is a sliding shaft portion, and the first rotating knob 2 is the first rotating knob 2. Since the operation knob 4 is attached to the operation rod 7 and the operation knob 4 is attached to the operation rod 7, the water in the switch body 8 is operated from the clearance between the operation knob 4 and the insertion hole 2b through the clearance between the operation rod 7 and the rod insertion hole 5c. This can be prevented without providing a seal member such as an O-ring between the rod 7 and the rod insertion hole 5c. Therefore, high waterproofness can be ensured without deteriorating the operability of the operation knob 4.

  Further, in the present embodiment, the waterproof member 23 is fixed to the first rotary knob 2 by waterproofing with the inner bottom surface of the base portion 2B of the first rotary knob 2 and the pressing rib 2d formed on the grip portion 2A. Since the flange (other end) 23a of the waterproof member 23 is fixed to the first rotary knob 2 by sandwiching the flange 23a of the member 23, the assembly as the operation unit 30 is simply attached to the first rotor 5. Thus, it is possible to reliably prevent water from entering the switch device 1 from the gap between the operation knob 4 and the first rotor 5.

  And in this Embodiment, when attaching the grip part 2A of the 1st rotation knob 2 to the base part 2B by fitting with the protrusion 2g and the hole 2e, the hole 2f connected to the protrusion 2g and the hole Since the gap portion δ (see FIG. 3) formed in communication with the portion 2e constitutes a drainage route, the fitting portion between the grip portion 2A and the base portion 2B also serves as the drainage route. The configuration can be simplified. As indicated by the arrow in FIG. 2, the water that has entered the first rotary knob 2 from the gap between the operation knob 4 and the insertion hole 2b of the first rotary knob 2 is pressed rib 2d. The two holes 2e formed in the above and the two holes 2f formed in the base 2B are discharged to the outside of the first rotary knob 2.

  Further, in the present embodiment, since a configuration in which one end of the waterproof member 23 is attached to the flange portion 4B of the operation knob 4 housed in the first rotary knob 2 is adopted, a bellows-like waterproof is provided outside the switch device 1. It is not necessary to cover the operation knob 4 by disposing a member, and since the operation knob 4 itself does not need to be made of rubber, the operation mechanism of the switch device 1 is not limited and the appearance can be improved.

  In addition, in the switch device 1 according to the present embodiment, the slider 9 to be pushed is arranged in the space between the first and second base members 12 and 13 divided into two parts. A cam mechanism for holding the slider 9 in the operating position can be efficiently arranged, and an alternate type push switch mechanism can be configured without increasing the size of the structure.

  Further, since the arrangement surface of the light switch circuit 20 and the flasher switch circuit 22 can be made large on the first and second slide members 14 and 15, for example, when the switch device 1 is used for a vehicle, a hazard switch It is possible to arrange two circuits for blinking the two side lamps.

  Furthermore, since the outer surface of the first and second base members 12 and 13 can be used to form a light switch and a flasher switch that can be switched by the first and second rotary knobs 2 and 3, respectively, The switch device 1 having a switch function can be downsized.

  In the present embodiment, the operating rod 7 for transmitting the operating force of the operating knob 4 to the slider 9 is inserted and held in the first rotor 5, and the second cylinder 5 </ b> A of the first rotor 5 is used for the second operation. Since the rotor 6 is rotatably supported and the operation knob 4 and the first and second rotors 5 and 6 are arranged on the same axis, the radial dimension of the switch device 1 can be kept small and the size can be reduced. The effect that it can plan is acquired.
