Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
As shown in FIG. 1, the turn signal switch according to the first embodiment is formed in a handle switch case 1 (case) fixed in the vicinity of a grip grip G of a handle bar H of a two-wheeled vehicle (vehicle). Then, by the sliding operation of the operation knob 2 (slide knob 2a) in the horizontal direction in the drawing, the movable contact and the fixed contact come into contact with each other and the winker (on either the left or right side) disposed on the two-wheeled vehicle. The turn signal flasher) is blinked, and the movable contact and the fixed contact are separated by the pushing operation of the operation knob 2 (push button 2b), so that blinking of the blinker can be canceled.

  More specifically, as shown in FIGS. 1 to 10, the turn signal switch includes a handle switch case 1 (case), a slide knob 2 a and a push button 2 b constituting the operation knob 2, and a movable contact 7. The interlocking member 5 and the terminal plate 6 on which the fixed contact 8 is formed are mainly configured. As described above, the handle switch case 1 can be fixed in the vicinity of the grip G of the handle bar H of the two-wheeled vehicle (vehicle). In addition to the turn signal switch according to the present invention, the headlight of the two-wheeled vehicle is lowered. A plurality of switches capable of operating electrical components mounted on the two-wheeled vehicle, such as a dimmer switch knob 3 for switching to irradiation or front irradiation or a horn switch knob 4 for sounding a horn, are provided. In the figure, symbol n indicates a screw for fixing the terminal plate 6 to the handle switch case 1, and the screw n is in a screw hole of a boss 1a (see FIG. 8) formed in the handle switch case 1. It can be inserted.

  The operation knob 2 (slide knob 2a, push button 2b) is formed so as to protrude from the handle switch case 1, and can be slid rightward and leftward from the neutral position, and can be pushed in from the neutral position. is there. In the present embodiment, the operation knob is composed of a slide knob 2a that is always urged to a neutral position and can be slid left and right, and a push button 2b that is formed on the slide knob 2a and can be pushed. Yes. In addition, it may have a single operation knob that can be slid right and left from the neutral position and that can be pushed from the neutral position.

  As shown in FIGS. 4 to 6, the slide knob 2a is slidably assembled with the handle switch case 1 in a straight line in the left-right direction, and is always urged to the neutral position by the coil spring S1. It consists of a part formed in a chevron with a protruding part. A through hole 2ab is formed at the center of the slide knob 2a, and the push button 2b is fitted into the through hole 2ab and assembled.

  The push button 2b is assembled so that it can be pushed into the handle switch case 1 (slide knob 2a), and is urged by the coil spring S2 so as to always protrude, and is composed of a substantially cylindrical part. Thus, when the slide knob 2a is slid to the left and right, the push button 2b follows, and when the push button 2b is pressed, the push button 2b can be pushed against the urging force of the coil spring S2. .

  In the push button 2b according to the present embodiment, a shaft member 11 inserted through the interlocking member 5 is formed to protrude. The shaft member 11 is composed of a rod-shaped member, and has a male screw formed on the base end 11b side. The push button is engaged by screwing the male screw with a female screw formed on the push button 2b. It is integrated with 2b, and the front-end | tip part 11a is made into a diameter smaller than the base end 11b. Reference numeral 9 in the figure denotes a spacer attached to the shaft member 11.

  In addition, an operation-side inclined surface 12 that can be opposed to an operated-side inclined surface 5g (described in detail later) formed on the interlocking member 5 is formed at a predetermined position of the shaft member 11. The operation-side inclined surface 12 is formed of a pair of left and right integrally formed at a predetermined position of the shaft member 11. Thus, when the sliding operation on the slide knob 2a is performed, the shaft member 11 moves in the left-right direction together with the push button 2b. When the pushing operation of the push button 2b is performed, the pushing direction (of the shaft member 11) (Longitudinal direction).

  The interlocking member 5 contacts or separates from the fixed contact 8 fixed to the handle switch case 1 side (specifically, the terminal plate 6) in conjunction with the sliding operation of the slide knob 2a and the pressing operation of the push button 2b. The movable contact 7 to be obtained is formed, a recess 5a through which the shaft member 11 can be inserted, a through hole 5b through which the tip end portion 11a of the shaft member 11 can pass, and a groove 5c into which the movable contact 7 can be fitted, It is mainly composed of an insertion hole 5d through which the swing shaft L can be inserted, a projection 5e, and an arm 5f. In the figure, symbol S3 indicates a coil spring for constantly urging the movable contact 7 toward the fixed contact 8 side.

  The concave portion 5a has a shape that is greatly opened toward the operation knob 2. When the slide knob 2a is slid in either the left or right direction, a part 2aa (see FIG. 7) of the slide knob 2a is opened to the concave portion 5a. The interlocking member 5 can be interlocked by pressing the wall portion. In addition, an operation-side inclined surface 5g is integrally formed at a predetermined portion of the recess 5a. When the slide knob 2a is slid, the operation-side inclined surface 5g and the shaft member 11 are formed. The operation side inclined surface 12 can be confronted.

  Here, the interlocking member 5 according to the present embodiment is assembled by inserting a swinging shaft L formed to protrude from the handle switch case 1 toward the terminal plate 6 into the insertion hole 5d. It can be swung around the swing axis L in conjunction with the sliding operation of the slide knob 2a and the pushing operation of the push button 2b. On the other hand, as shown in FIG. 8, the arm portion 5f extends in a predetermined direction from the swing axis L, and a groove portion 5c for attaching the movable contact 7 along the extending direction of the arm portion 5f. Is formed. As a result, the movable contact 7 swings in the same direction as the interlocking member 5 swings.

  As shown in FIG. 12, when the slide knob 2a is in the neutral position, the movable contact 7 has one end in contact with the ground contact g and the other end substantially in the middle of the pair of fixed contacts 8 as shown in FIG. It is located and is in a state separated from any fixed contact 8. In this state, the blinkers on both the left and right sides of the motorcycle are not blinking. When the slide knob 2a is slid to the right from the neutral position, the interlocking member 5 swings clockwise about the swing axis L, and as shown in FIG. While the contact with the earth contact g is maintained, the other end contacts the one fixed contact 8 to blink the right blinker, and when the slide knob 2a is slid from the neutral position to the left, the interlocking member 5 swings. As shown in FIG. 5C, the movable contact 7 is kept in contact with the ground contact g while the other end is in contact with the other fixed contact 8 as shown in FIG. The blinker on the left is blinking.

  Further, if the push button 2b is pushed in after the slide knob 2a is slid in either the left or right direction, the operation side inclined surface 12 and the operated side inclined surface 5g face each other. In this state, the shaft member 11 moves in the longitudinal direction, and the movable contact 7 can be separated from the fixed contact 8 by interlocking the interlocking member 5 by the cam action by the operation-side inclined surface 12 and the operated-side inclined surface 5g. It has become.

  Note that a housing hole for housing the coil spring S4 is formed in the protruding portion 5e of the interlocking member 5, and the ball 10 biased by the coil spring S4 is assembled. The coil spring S4 and the ball 10 can maintain a swinging state of the interlocking member 5 by a sliding operation of the slide knob 2a, and constitute a moderation providing unit that provides a moderation when the slide knob 2a is slid left and right. is doing.

  Further, a convex portion 13 is formed on the handle switch case 1 along the movement trajectory of the ball 10 accompanying the swing of the interlocking member 5, and the interlocking member 5 is in the initial state in the convex portion 13. The insertion recess 13a for inserting the ball 10 when in position, the insertion recess 13b for inserting the ball 10 when swinging clockwise, the insertion recess for inserting the ball 10 when swinging counterclockwise 13c is formed.

  That is, when the slide knob 2a is in the neutral position, as shown in FIG. 11A, the interlocking member 5 is in the initial state, and the ball 10 is inserted into the insertion recess 13a. Then, for example, when the slide knob 2a is slid to the right, the interlocking member 5 in the initial state swings about the swinging shaft L, and the state shown in FIG. It is assumed that it is inserted. Thereby, in the swinging process of the interlocking member 5, the ball 10 is detached from the insertion recess 13 a and is inserted into the adjacent insertion recess 13 b, so that moderation can be given during the sliding operation of the slide knob 2 a and the interlocking operation is performed. After the member 5 swings, the ball 10 is inserted into the insertion recess 13b, so that the swinging state is maintained.

  When the operating force on the slide knob 2a is loosened in such a state, the swinging state of the interlocking member 5 is maintained as shown in FIG. 3C, while the slide knob 2a is neutralized by the biasing force of the coil spring S1. It will be returned to the position. In this state, the movable contact 7 is in contact with one fixed contact 8 (see FIG. 12B). For example, the right blinker can be blinked and one (left side in the figure). The operation-side inclined surface 12 and one (left side in the figure) operated-side inclined surface 5g face each other. When the slide knob 2a is slid to the left, the other (right side in the figure) operation side inclined surface 12 and the other (right side in the figure) operated side inclined surface 5g face each other. .

  Thereafter, as the push button 2b is pushed in, the shaft member 11 moves in the longitudinal direction. As shown in FIG. 4D, the cam is formed by the operation side inclined surface 12 and the operated side inclined surface 5g. As a result, the interlocking member 5 can be interlocked to return to the initial state. As a result, the movable contact 7 can be separated from the one fixed contact 8 to reach an intermediate position with the other fixed contact 8, and blinking of the blinker can be canceled (flashing stopped). However, even in the canceling operation process, the ball 10 is removed from the insertion recess 13b and is inserted into the adjacent insertion recess 13a, so that a moderation can be given during the sliding operation of the slide knob 2a and the interlocking member 5 can be swung. After the movement, since the ball 10 is inserted into the insertion recess 13a, the initial state is maintained. Even when the slide knob 2a is slid to the left, a series of actions similar to the above are exhibited.

  Furthermore, in the turn signal switch according to the present embodiment, guide means for guiding the pushing operation of the operation knob 2 (push button 2b) is provided. As shown in FIG. 10, the guide means comprises an insertion hole 6a (insertion portion) formed in the terminal plate 6. After the slide knob 2a is slid in either the left or right direction, the slide knob 2a is neutral. When the push button 2b is pushed in when in the position, the distal end portion 11a of the shaft member 11 can be inserted into the insertion hole 6a.

  Thus, when the push button 2b is pushed in to cancel blinking of the blinker, the distal end portion 11a of the shaft member 11 is inserted into the insertion hole 6a, and the longitudinal direction of the push button 2b is restricted while restricting the radial movement thereof. Since the movement in the (axial direction) is guided, the operability can be improved more reliably. Further, as shown in FIG. 13, if the tip end portion 11a of the shaft member 11 is tapered, the positions of the tip end portion 11a of the shaft member 11 and the fitting hole 6a are slightly shifted when the push button 2b is pushed. Moreover, the said front-end | tip part 11a can be reliably and smoothly inserted in the insertion hole 6a, and operativity can be improved further. In addition, it may replace with the insertion hole 6a of this embodiment, and may be an insertion recessed part which consists of a bottomed shape.

  Furthermore, the guide means according to the present embodiment has a groove shape 6b that extends linearly in the left-right direction from the insertion hole 6a (or the insertion recess), and with the sliding operation of the slide knob 2a by the groove shape 6b. The tip portion 11a of the moving shaft member 11 can be guided. That is, the tip end portion 11a of the shaft member 11 is inserted into the groove shape 6b, and the movement of the shaft member 11 accompanying the sliding operation of the slide knob 2a is guided, and the substantially center of the groove shape 6b. An insertion hole 6a (or an insertion recess) is formed in the.

  Thus, the sliding movement of the slide knob 2a can be guided by guiding the movement of the shaft member 11 in the left-right direction by the groove shape 6b, and the length of the shaft member 11 can be increased by the insertion hole 6a (or the insertion recess). By guiding the movement of the direction, it is possible to guide the push-in operation of the push button 2b, and it is possible to improve the operability of both the sliding operation and the pushing operation. Moreover, in this embodiment, since the insertion hole 6a (or insertion recessed part) and groove shape 6b which comprise a guide means are formed in the terminal board 6, the separate new component for arrange | positioning a guide means is provided. It can be unnecessary.

  According to the first embodiment, since the guide means for guiding the push operation of the operation knob 2 (push button 2b) is provided, the operability during the push operation of the operation knob 2 (push button 2b) is improved. Thus, the blinker can be canceled more smoothly and surely. The push button 2b has an operation-side inclined surface 12 that can be opposed to the operated-side inclined surface 5g formed on the interlocking member 5 by a sliding operation of the slide knob 2a, and the operation-side inclined surface 12 during a push-in operation. Since the movable contact 7 can be separated from the fixed contact 8 by interlocking the interlocking member 5 by the cam action by the operated side inclined surface 5g, the blinker blinking can be canceled with a relatively simple configuration. be able to.

  In particular, in the present embodiment, the operation-side inclined surface 12 and the operated-side inclined surface 5g are formed in a curved shape following the swinging locus of the interlocking member 5, as shown in FIGS. In other words, the surfaces (facing surfaces) acting as cams on the operation-side inclined surface 12 and the operated-side inclined surface 5g are curved surfaces having the same curvature as the swing locus of the interlocking member 5. As a result, when the push button 2b is pushed in, the operation-side inclined surface 12 can be satisfactorily brought into contact with the operated-side inclined surface 5g, and the cam action can be reliably achieved. Therefore, the pushing operation force of the push button can be more reliably transmitted to the interlocking member, and the blinker can be canceled more reliably and smoothly.

  Further, according to the present embodiment, the push button 2b is formed by protruding the shaft member 11 inserted through the interlocking member 5, and the operation member inclined surface 12 is formed on the shaft member 11, so that the slide knob The interlocking member 5 can be swung reliably and smoothly during the push-in operation of the push button 2b while allowing the interlocking member 5 to swing according to the sliding operation 2a. Further, the interlocking member 5 is formed on the interlocking member 5 and can hold the swinging state of the interlocking member 5 by the sliding operation of the operation knob 2 (slide knob 2a). Since the moderation means for imparting moderation during the dynamic operation is provided, it is possible to further improve the operability during the left / right sliding operation of the operation knob (slide knob 2a).

  The interlocking member 5 can swing about a predetermined swinging axis L in conjunction with the sliding operation and pushing operation of the operation knob 2, so that the sliding operation of the operation knob 2 (slide knob 2a) is performed. Accordingly, the movable contact 7 of the interlocking member 5 can be operated relatively large, and the movable contact 7 can be reliably brought into contact with or separated from the fixed contact 8. In particular, in the present embodiment, the distance between the operation knob 2 (shaft member 11) and the swing axis L of the interlocking member 5 (dimension X in FIG. 11A) is fixed to the fixed contact 8 of the movable contact 7. The dimension between the contact portion and the swing axis L of the interlocking member 5 (dimension Y in FIG. 11A) is set larger (X <Y). Thereby, it is possible to easily and surely move the movable contact 7 in accordance with the sliding operation of the operation knob 2 (slide knob 2a), and the movable contact 7 is brought into contact with or separated from the fixed contact 8. Furthermore, it can be performed reliably.

Next, a turn signal switch according to a second embodiment of the present invention will be described.
14 to 22, the turn signal switch according to the present embodiment is formed in a handle switch case 1 (case) fixed in the vicinity of a grip grip G of a handle bar H included in a two-wheeled vehicle (vehicle). As in the first embodiment, the movable contact and the fixed contact are brought into contact with the desired side (left and right) by the sliding operation of the operation knob 14 (slide knob 14a) in the horizontal direction in the drawing.

The same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In particular, in the present embodiment, a main component is housed in a housing case 1b fixed to the handle switch case 1, thereby constituting a unit. By assembling such a unit to the handle switch case 1, a desired side can be obtained. It is assumed that blinking of the blinker (turn signal flasher) and cancellation of blinking of the blinker can be performed. The housing case 1b is engaged with the terminal plate 16 to constitute a unit, and a housing space capable of housing main components is formed in the housing case 1b and the terminal plate 16. Further, an opening 1ba (see FIG. 16) is formed in the housing case 1b, and the operation knob 14 can be formed to protrude through the opening 1ba.

  The operation knob 14 (slide knob 14a, push button 14b) is formed so as to protrude from the handle switch case 1, and can be slid rightward and leftward from the neutral position, and can be pushed in from the neutral position. is there. That is, the operation knob 14 includes a slide knob 14a that is always urged to a neutral position and can be slid left and right, and a push button 14b that is formed on the slide knob 14a and can be pushed. In addition, it may have a single operation knob that can be slid right and left from the neutral position and that can be pushed from the neutral position.

  The slide knob 14a is assembled to the handle switch case 1 so as to be slidable linearly in the left-right direction, and is always urged to the neutral position by the coil spring S1, and is formed in a mountain shape with a protruding central portion. Consists of parts. The push button 14b is assembled so that it can be pushed into the handle switch case 1 (slide knob 14a) and is urged by the coil spring S2 so as to always protrude, and is composed of a substantially cylindrical part. When the slide knob 14a is slid left and right, the push button 14b also follows, and when the push button 14b is pressed, the push button 14b can be pushed against the urging force of the coil spring S2.

  In the push button 14b according to the present embodiment, a shaft member 20 inserted through the interlocking member 15 is formed to protrude. The shaft member 20 is composed of a rod-like member, and is integrated with the push button 14b by means such as press-fitting or insert molding, and as shown in FIG. 27, the tip portion 20a is formed in a tapered shape. Has been.

  Further, as shown in the figure, a sliding portion 21 made of a pair of plate-like members formed at a predetermined distance is formed on the distal end side (the side where the distal end portion 20a is formed) of the shaft member 20. On the side surface of each sliding portion 21, an operation side inclined surface 21a that can be opposed to an operated side inclined surface 15d (described in detail later) formed on the interlocking member 15 is formed. The operation-side inclined surface 21a is formed of a part integrally formed with a pair of left and right in each sliding portion 21 of the shaft member 20. Thus, when the sliding operation on the slide knob 14a is performed, the shaft member 20 moves in the left-right direction together with the push button 14b, and when the push button 14b is pushed, the pushing direction (of the shaft member 20) (Longitudinal direction).

  The interlocking member 15 can be interlocked with the sliding operation of the slide knob 14a and the pressing operation of the push button 14b, and the fixed contact 18 fixed to the handle switch case 1 side (specifically, the terminal plate 16). A movable contact 17 that can be contacted or separated is formed, and a concave portion 15a through which the shaft member 20 can be inserted, a through hole 15b through which the tip portion 20a of the shaft member 20 can be inserted, and the movable contact 17 can be fitted. It is mainly comprised from the groove part 15c.

  The concave portion 15a has a shape that is greatly opened toward the operation knob 14, and when the slide knob 14a is slid in either the left or right direction, a part of the slide knob 14a presses the opening wall portion of the concave portion 15a. The interlocking member 15 can be interlocked. In addition, an operation-side inclined surface 15d is integrally formed at a predetermined portion of the recess 15a. When the slide knob 14a is slid, the operation-side inclined surface 15d and the shaft member 20 are formed. The operation side inclined surface 21a can be confronted.

  Here, the interlocking member 15 according to the present embodiment is interlocked with the sliding operation of the slide knob 14a and the pressing operation of the push button 14b, and in the left and right direction (the same direction as the direction of the slide knob 14a) in the unit (housing case 1b). ) Is slid (slid) substantially linearly. Accordingly, the movable contact 17 slides in the same direction as the interlocking member 15 slides (slides).

  As shown in FIG. 26, when the slide knob 14a is in the neutral position, the movable contact 17 is positioned substantially in the middle of the pair of fixed contacts 18 as shown in FIG. It is assumed that In this state, the blinkers on both the left and right sides of the motorcycle are not blinking. When the slide knob 14a is slid to the left from the neutral position, the interlocking member 15 slides in the same direction, and the movable contact 17 is connected to the ground contact g and the left fixed contact 18 as shown in FIG. When the slide knob 14a is slid to the right side from the neutral position, the interlocking member 15 slides in the same direction, and as shown in FIG. Is in contact with the ground contact g and the right fixed contact 18 to blink the right blinker.

  Furthermore, if the push button 14b is pushed in after the slide knob 14a is slid in either the left or right direction and then returned to the neutral position, the operation side inclined surface 21a and the operated side inclined surface 15d face each other. In this state, the shaft member 20 moves in the longitudinal direction, and the movable contact 17 can be separated from the fixed contact 18 by interlocking the interlocking member 15 by the cam action of the operation-side inclined surface 21a and the operated-side inclined surface 15d. It has become.

  The interlocking member 15 is formed with an accommodation hole for accommodating the coil spring S4, and a ball 19 biased by the coil spring S4 is assembled thereto. The coil spring S4 and the ball 19 can maintain a sliding state of the interlocking member 15 by a sliding operation of the slide knob 14a, and constitute a moderation providing means for applying a moderation when the sliding knob 14a is slid left and right. is doing. That is, an uneven shape (not shown) is formed on the handle switch case 1 side (accommodating case 1b) along the movement locus of the ball 19 as the interlocking member 15 slides, and the interlocking member 15 is in the initial state. In some cases, when sliding to the left side and sliding to the right side, they are respectively fitted into the recesses in the concavo-convex shape, and the respective states are maintained.

  However, when the slide knob 14a is in the neutral position, as shown in FIGS. 20 to 22, the interlocking member 15 is in the initial state. For example, when the slide knob 14a is slid to the right, as shown in FIG. The interlocking member 15 slides following the same direction (right side). When the operation force on the slide knob 14a is loosened in such a state, as shown in FIG. 24, the sliding state of the interlocking member 15 is maintained by the insertion of the ball 19 into the concavo-convex shape, while the slide knob 14a has the coil spring S1. It is returned to the neutral position by the urging force.

  In this state, the movable contact 17 is in contact with one fixed contact 18 (see FIG. 26 (c)). For example, the right blinker can be blinked and one (left side in the figure). The operation side inclined surface 21a and one (left side in the figure) operated side inclined surface 15d face each other. When the slide knob 14a is slid to the left, the other (right side in the figure) operation side inclined surface 21a and the other (right side in the figure) operated side inclined surface 15d face each other. .

  Thereafter, when the push button 14b is pushed in, the shaft member 20 is moved in the longitudinal direction along with the operation, and as shown in FIG. 25, the cam action by the operation side inclined surface 21a and the operated side inclined surface 15d. Thus, the interlocking member 15 can be interlocked to return to the initial state. Accordingly, the movable contact 17 can be separated from the one fixed contact 18 to reach an intermediate position between the two fixed contacts 18, and blinking of the blinker can be canceled (flashing stopped). Even when the slide knob 14a is slid to the left, a series of actions similar to the above are performed.

  Furthermore, in the turn signal switch according to the present embodiment, guide means for guiding the pushing operation of the operation knob 14 (push button 14b) is provided. As shown in FIGS. 16 and 20 to 25, the guide means is formed integrally with the terminal plate 16, and is mainly composed of a separation portion 16 a (insertion portion) and a pair of slide rails 16 b. Has been. The pair of slide rails 16b are formed in the shape of ridges that are formed in a substantially straight line while being spaced apart from each other by a predetermined dimension at the center. As shown in FIG. It is set so that it can be clamped in the width direction.

  Thus, the slide rail 16b is configured to guide the distal end portion 20a of the shaft member 20 that moves in accordance with the sliding operation of the slide knob 14a. That is, since the pair of sliding portions 21 formed on the distal end side of the shaft member 20 is sandwiched in the width direction of the slide rail 16b, the movement in the width direction is restricted and sliding is performed. Movement of the rail 16b in the extending direction is allowed, and the movement of the shaft member 20 accompanying the sliding operation of the slide knob 14a in the left-right direction is guided.

  On the other hand, the separation portion 16a (insertion portion) of the slide rail 16b has a dimension (separation dimension) through which the tip end portion 20a of the shaft member 20 can be inserted. When the slide knob 14a is at the neutral position, the push button 14b is The distal end portion 20a of the shaft member 20 can be fitted by performing a pushing operation. That is, after the slide knob 14a is slid in either the left or right direction, when the push button 14b is pushed in when the slide knob 14a is in the neutral position, the distal end portion 20a of the shaft member 20 is separated from the slide rail 16b. It is comprised so that it can be made to fit in a part (insertion part).

  Thus, when the push button 14b is pushed in to cancel blinking of the blinker, the distal end portion 20a of the shaft member 20 is inserted into the separation portion 16a (insertion portion), and the radial movement of the push button 14b is restricted. However, since the movement in the longitudinal direction (axial direction) is guided, the operability can be improved more reliably. Further, in the present embodiment, as shown in FIGS. 20 and 27 and the like, the distal end portion 20a of the shaft member 20 is tapered, so that the distal end portion 20a of the shaft member 20 is pushed when the push button 14b is pushed. Even if the positions of the separation portion 16a (insertion portion) are slightly shifted, the distal end portion 20a can be reliably and smoothly inserted into the separation portion 16a (insertion portion), and the operability can be further improved. .

  Accordingly, the sliding movement of the slide knob 14a can be guided by guiding the movement of the shaft member 20 in the left-right direction by the sliding rail 16b, and the separating portion 16a (insertion portion) of the sliding rail 16b. Thus, the pushing operation of the push button 14b can be guided by guiding the movement of the shaft member 20 in the longitudinal direction, and the operability during both the sliding operation and the pushing operation can be improved. In the present embodiment, since the slide rail 16b and the separating portion 16a constituting the guide means are formed on the terminal plate 16, no separate new components for arranging the guide means are required. Can do.

  According to the second embodiment, as in the first embodiment, since the guide means for guiding the push operation of the operation knob 14 (push button 14b) is provided, the push operation of the operation knob 14 (push button 14b) is provided. The operability at the time can be improved, and the blinker can be canceled more smoothly and reliably. The push button 14b has an operation-side inclined surface 21a that can be opposed to the operated-side inclined surface 15d formed on the interlocking member 15 by the sliding operation of the slide knob 14a, and the operation-side inclined surface 21a during the push-in operation. Since the movable contact 17 can be separated from the fixed contact 18 by interlocking the interlocking member 15 by the cam action by the operated side inclined surface 15d, the blinker blinking can be canceled with a relatively simple configuration. be able to.

  In particular, in the present embodiment, the guide means is formed with a pair of left and right protruding rails 16b that slide and guide the tip portion 20a of the shaft member 20 in accordance with the sliding operation of the slide knob 14a. At the same time, the spacing portion 16a of the pair of left and right slide rails 16b forms the insertion portion of the tip portion 20a. Therefore, the slide rail 16b guides the movement of the shaft member 20 in the left-right direction, so that the slide knob 14a The sliding operation can be reliably guided, and the pushing operation of the push button 14b is guided by guiding the movement of the shaft member 20 in the longitudinal direction by the fitting portion formed of the separation portion 16a of the sliding rail 14a. Therefore, the operability during both the sliding operation and the pushing operation can be further improved.

  Although the present embodiment has been described above, the present invention is not limited to this. For example, the first embodiment includes the interlocking member 5 that swings with the sliding operation of the slide knob 2a. Instead of this, an interlocking member that slides substantially linearly with the sliding operation of the slide knob 2a may be provided. Further, in the first embodiment, the guide means is composed of only the insertion hole 6a (or the insertion concave portion) into which the tip end portion 11a of the shaft member 11 is inserted, and the groove shape 6b extending linearly in the left-right direction is not formed. It may be a thing.

  Further, in the first embodiment, the interlocking member 5 can be held in the swinging or sliding state by the sliding operation of the slide knob 2a instead of the moderation providing means including the coil spring S4 and the ball 10, and the slide knob 2a. It is good also as what comprised the moderation provision means of the other form which provides moderation at the time of left-right sliding operation. In the second embodiment, the tip 20a of the shaft member 20 is preferably tapered as shown in FIG. 27. Alternatively, the tip 20a is not tapered or chamfered. It is good also as what was made. In this embodiment, the present invention is applied to a turn signal switch attached to a handlebar of a two-wheeled vehicle, but may be applied to other vehicles having a handlebar such as a snowmobile, a three-wheel or a four-wheel buggy. it can.

  As long as the turn signal switch is provided with a guide means for guiding the push operation of the operation knob, it can also be applied to a switch with a different external shape or with another function added.
