  3, symbol a is a support member that rotatably supports the rotor 2, symbol b is a support plate that slidably supports the slide member 4, symbol c is a partition plate, and symbol d is a lower opening of the cylinder body 1. The cover member which covers and closes is shown. Reference numeral S denotes a coil spring that urges the rotor 2, the first cam member 3, and the second cam member upward. This allows the rotor 2 to be pressed and is attached after the pressing operation. The power returns to the initial position.

  The cylinder body 1 is composed of a die-cast molded product or the like that opens at least upward and downward, and constitutes the casing of the ignition switch device. A substantially cylindrical rotor 2 is disposed on the cylinder body 1 so as to be rotatable about its axis. The rotor 2 has a key hole 2a (see FIG. 1) through which an ignition key IK (see FIG. 2) can be inserted, and a plurality of tumblers 2b formed therein.

  In a state where the ignition key IK is not inserted into the key hole 2a, each tumbler 2b is locked to the cylinder body 1 side and the rotation of the rotor 2 is restricted, and the ignition key IK is inserted into the key hole 2a. Then, the locking by each tumbler 2b is released, and the rotation of the rotor 2 is allowed. Note that the rotor 2 according to the present embodiment has a locking hole 2c that can be locked with the first cam member 3 at the lower end thereof.

  Further, as shown in FIG. 1, the rotor 2 is set to an off position A and one rotational direction (clockwise) from the off position A to start the vehicle engine with the ignition key IK inserted. Between the off position A and the steering lock position C, which is set in the other rotational direction (counterclockwise) from the off position A and locks the steering of the vehicle. It is configured to reach the steering lock position C by rotating while pressing in the rotation direction.

  Specifically, when the rotor 2 is rotated from the off position A to the on position B, the battery circuit of the vehicle is connected. In this state, the engine is operated by pressing a separate starter button (not shown) or the like. When the rotor 2 is rotated from the OFF position A to the steering lock position C while being rotated, the lock bar 5 is slid in the direction protruding from the cylinder body 1 and the tip thereof is Steering lock is possible by fitting into a hole formed in the steering shaft (not shown).

  Here, in the present embodiment, from the off position A to the other rotation direction (counterclockwise), from the steering lock position C to the other rotation direction (counterclockwise), and from the on position B to one rotation direction (clockwise rotation). ), And the seat lock release positions (D, E, F) at which the seat lock of the vehicle can be released and the seat can be opened are set. That is, the seat lock release position D counterclockwise from the off position A, the seat lock release position E counterclockwise from the steering lock position C, and the seat lock release position F clockwise from the on position B. Is set for each.

  Further, in the present embodiment, the rotor 2 is rotated while being pressed in one rotational direction (clockwise) from the off position A of the rotor 2 (in the present embodiment, further than the on position B and the seat lock release position D). A fuel tank open position G for opening the fuel tank cap of the vehicle is set at a clockwise position). Thus, in this ignition switch device, in addition to general-purpose functions such as engine start and steering lock, it has a seat lock release function and a fuel tank cap open function (so-called multi-function) Ignition switch device).

  As shown in FIGS. 4 to 6, the first cam member 3 is composed of a member that is formed in a substantially axial shape as a whole, and includes a locking portion 3 a at the upper end portion and an arm portion 3 b that extends laterally. The lower end portion has a large diameter portion 3c and an engagement hole 3ca formed in the large diameter portion 3c. The locking portion 3 a is a portion that is inserted and locked into a locking hole 2 c formed in the lower end portion of the rotor 2, whereby the rotor 2 and the first cam member 3 are connected together with the rotor 2. The first cam member 3 is configured to be able to rotate.

  The arm portion 3b has a distal end portion 3ba that extends from the side and bends downward on the distal end side, and the first cam member 3 rotates as the rotor 2 rotates. It can rotate in the same direction. The large-diameter portion 3c is formed of a circular portion whose diameter is set larger than that of the other shaft portion, and an engagement hole 3ca that can be engaged with the upper end portion (engagement portion 6ea) of the second cam member 6 is provided therein. Is formed. Thus, as the rotor 2 and the first cam member 3 rotate, the second cam member 6 can be interlocked and rotated in the same direction.

  As shown in FIGS. 7 to 10, the slide member 4 is composed of parts formed in a rectangular shape (block shape) as a whole, and has a long hole 4 a extending in the sliding direction of the slide member 4 and the long hole 4 a. A pair of holes formed at positions corresponding to the long hole 4a on the back surface side of the slide member 4 and the groove 4b that extends continuously from side to side, the locking groove 4c that can be locked to the base end of the lock bar 5 It is mainly composed of parts r1 and r2.

  The long hole 4a is set to have a width that allows the first cam member 3 to be inserted, and the slide member 4 slides (the lock bar 5 in a state where the first cam member 3 is inserted into the long hole 4a. (Sliding in the moving direction) can be allowed. Further, the locking groove 4 c is formed of a recess having a shape substantially equal to the base end portion of the lock bar 5, and can be assembled to the slide member 4 by locking the lock bar 5.

  The groove 4b is composed of a bottomed recess that is set to a width dimension that allows the distal end portion 3ba of the arm portion 3b of the first cam member 3 to be fitted therein. And a short extending portion 4bb extending short from the base end side of the long hole 4a to the other side. Thus, as the first cam member 3 rotates, when the arm portion 3b rotates toward the arcuate portion 4ba, the tip portion 3ba of the arm portion 3b can move along the arcuate portion 4ba, and the arm When the part 3b rotates to the short extension part 4bb side, the tip part 3ba of the arm part 3b moves along the short extension part 4bb.

  At this time, when the distal end portion 3ba moves along the arcuate portion 4ba side, the distal end portion 3ba does not interfere with the inner wall surface of the arcuate portion 4ba, and only the distal end portion 3ba moves. When the distal end portion 3ba moves along the extending portion 4bb side, the distal end portion 3ba comes into contact with the inner wall surface of the distal end of the short extending portion 4bb, and the arm portion 3b further rotates from there to slide. The entire member 4 can be slid in the extending direction of the long hole 4a.

  The pair of holes r1 and r2 are arranged in parallel in the extending direction of the long hole 4a, and are formed of a recess communicating with the long hole 4a. Each of the holes r1 and r2 can fit the large-diameter portion 3c of the first cam member 3. And the shape. When the lock bar 5 does not protrude and the rotor 2 is not pressed, the large-diameter portion 3c of the first cam member 3 is fitted into the hole r2, and the lock bar 5 protrudes and the rotor 2 is not pressed. Then, it assembled | attached so that the large diameter part 3c of the 1st cam member 3 might be in the state inserted by the hole part r1.

  Thus, when the rotor 2 is not pressed, the large-diameter portion 3c of the first cam member 3 is in a state of being fitted into either the hole r1 or r2, and the slide (sliding) of the slide member 4 is performed. When the rotor 2 is pressed while being regulated, the large-diameter portion 3c of the first cam member 3 moves downward, disengages from the hole r1 or r2, and is disengaged. It is configured to allow sliding.

  That is, by pressing the rotor 2 at the off position A, the large diameter portion 3c is disengaged from the hole r2, and the rotor 2 is rotated in the other rotational direction (counterclockwise) while maintaining the pressed state. When rotated, the tip 3ba of the arm 3b rotates along the short extension 4bb, so that the slide member 4 slides to project the lock bar 5 and the steering lock is achieved. When the rotor 2 at the off position A is pressed and rotated in one direction of rotation (clockwise), the distal end portion 3ba of the arm portion 3b rotates along the arcuate portion 4ba side. 4 does not slide and the steering lock is not made.

  Here, on the lower side of the cylinder body 1, as shown in FIGS. 2 and 3, a unit Y accommodating a mechanism for releasing the seat lock and a mechanism for opening the fuel tank is disposed. Furthermore, a switch mechanism (comprising the movable terminal 12 and the terminal block 14) for forming a predetermined electric circuit in accordance with the rotation operation of the rotor 2 is disposed in the lower part. The mechanism for unlocking the seat lock in the unit Y includes the seat lock actuator 8, and the mechanism for opening the fuel tank includes the fuel tank open actuator 10. In addition, a second cam member 6 for selectively operating the seat lock operating element 8 and the fuel tank opening operating element 10 is disposed in the unit Y.

  The seat lock actuator 8 is connected to a seat lock (not shown) of the vehicle via a wire (not shown), and moves (slids) from the non-actuated position to the actuated position, thereby moving the lock portion of the seat lock mechanism. The seat lock can be released by a pulling operation, and as shown in FIG. 3, a convex portion 8a is integrally formed on the side surface. The seat lock actuator 8 is provided with a coil spring 9 (biasing means) that constantly urges the seat lock actuator 8 toward the non-actuated position, and resists the urging force of the coil spring 9. Thus, it can be operated from the non-operating position to the operating position.

  The fuel tank opening operator 10 is connected to a fuel tank opening mechanism (not shown) for opening the fuel tank via a wire (not shown), and operates (slids) from the non-operating position to the operating position. The fuel tank can be opened by pulling the tank opening mechanism, and as shown in FIG. 3, a convex portion 10a is integrally formed on the side surface. Like the seat lock actuator 8, the fuel tank open actuator 10 is provided with a coil spring 11 that constantly biases the fuel tank open actuator 10 toward the non-operating position. 11 is operable from the non-operating position to the operating position against the urging force of 11.

  As shown in FIGS. 11 and 13, the second cam member 6 is formed by integrally forming a substantially disc-shaped cam forming portion 6 f and a shaft portion 6 e forming the rotation center of the second cam member 6. A fitting portion 6ea that can be fitted into the engagement hole 3ca of the first cam member 3 is formed at the upper end portion of the shaft portion 6e, and a key-like engagement protruding in the lateral direction is formed at the lower end portion. A joint portion 6eb is formed. The fitting hole 3ca and the fitting portion 6ea have substantially the same shape and dimensions, and by fitting them, the first cam member 3 and the second cam member 6 are connected to rotate the rotor 2. These are configured so that they can rotate integrally in response to the operation.

  That is, the ignition switch device according to the present embodiment includes a first cam member 3 for operating the slide member 4 and the lock bar 5 for steering lock, and a seat lock actuator 8 for releasing the seat lock and opening the fuel tank. And the second cam member 6 for operating the fuel tank opening operator 10 are configured separately, and these are integrated by being locked and combined in the cylinder body 1 when the apparatus is assembled. It is.

  On the other hand, the second cam member 6 can be interlocked with the rotation of the rotor 2, and as shown in FIGS. 11 and 13, a predetermined direction convex portion (first predetermined direction convex portion 6 a and second predetermined direction convex portion. 6b), an anti-predetermined direction convex portion 6c, and a fuel tank opening convex portion 6d are integrally formed with the cam forming portion 6f, respectively. As shown in the figure, the predetermined direction convex portions (the first predetermined direction convex portion 6a and the second predetermined direction convex portion 6b) and the anti-predetermined direction convex portion 6c are the upper surface of the cam forming portion 6f, the fuel The tank opening convex portion 6d is formed to protrude from the back surface of the cam forming portion 6f.

  The predetermined direction convex portions (the first predetermined direction convex portion 6a and the second predetermined direction convex portion 6b) are rotated by the second cam member 6 by the rotation of the rotor 2 in a predetermined direction (counterclockwise: the other rotational direction). Are rotated in the same direction, the convex portion 8a of the seat lock operating element 8 can be pressed to move from the non-operating position to the operating position. That is, when the rotor 2 is rotated from the off position A in the other rotation direction (counterclockwise) (not pressed at this time) to reach the seat lock release position D, as shown in FIGS. 1 The convex portion 6a for a predetermined direction presses the convex portion 8a, and the operating member (see FIG. 14 (b)) from the non-operating position (see FIG. 14 (a)) against the urging force of the coil spring 9 16), and the rotor 2 is rotated from the steering lock position C in the other rotation direction (counterclockwise) (not pressed at this time) to reach the seat lock release position E, FIG. 17, the second predetermined direction convex portion 6 b presses the convex portion 8 a, and the seat locking actuator 8 is in the non-actuated position against the urging force of the coil spring 9 (see FIG. 17A). To the operating position (see (b) in the figure) A.

  The anti-predetermined direction convex portion 6c swings the operating arm 7 and deactivates the seat lock operating element 8 when the rotor 2 rotates in a direction opposite to the predetermined direction (counterclockwise: one rotation direction). It can be moved from the position to the working position. The operating arm 7 is disposed so as to be able to swing around one end across the radial direction of the second cam member 6, and the other end is locked to the seat lock operating element 8. As shown in FIG. 2, the swinging shaft L formed at one end, the locking convex portion 7a formed at the other end and locked to the seat locking actuator 8, and the bent portion 7b formed at the substantially center. It consists of a plate-shaped member having Further, the operating arm 7 according to the present embodiment avoids interference with the shaft portion 6e of the second cam member 6 at the bent portion 7b, and extends over the diameter direction of the second cam member 6. (That is, the direction passing through the rotation center of the second cam member 6).

  Thus, when the rotor 2 is rotated from the ON position B in one rotational direction (clockwise) (at this time, it is not pressed) to reach the seat lock release position F, as shown in FIGS. The anti-predetermined direction convex portion 6 c presses the operating arm 7 and swings about the swinging shaft L, and the seat lock actuator 8 locked to the locking convex portion 7 a resists the biasing force of the coil spring 9. Then, it is slid from the non-operating position (see FIG. 18A) to the operating position (see FIG. 18B). That is, when the rotor 2 rotates in one direction of rotation (the direction opposite to the predetermined direction), the operating force is transmitted through the operating arm 7 to change the operating direction, and to the seat lock operating element 8. Thus, the same operation as when the rotor 2 rotates in the other rotation direction (predetermined direction) can be performed.

  When the rotor 2 rotates from the off position A to the fuel tank open position G, the fuel tank open convex portion 6d presses the convex portion 10a of the fuel tank open actuator 10 to move from the non-operating position to the operating position. To get. That is, when the rotor 2 is rotated from the off position A while being pressed in one rotation direction (clockwise) to reach the fuel tank open position G, as shown in FIGS. Presses the convex portion 10a and slides the fuel tank opening actuator 10 from the non-operating position (see FIG. 20A) to the operating position (see FIG. 20B) against the biasing force of the coil spring 11. To make it happen.

  As shown in FIG. 22, the movable terminal 12 has a cross groove 12a formed at the upper end side and a movable contact 13 formed at the lower end side, and the second cam member 6 is formed in the cross groove 12a. The engaging portion 6eb is inserted and can be engaged. That is, when the rotor 2 is not pressed, the engaging portion 6eb of the second cam member 6 is engaged with the cross groove 12a, and the first cam member 3 is rotated with the rotation of the rotor 2. When the second cam member 6 rotates, the movable terminal 12 also rotates in conjunction with it, and when the rotor 2 is pressed, the second cam member 6 descends, and the engaging portion 6eb and the cross groove 12a Thus, even when the rotor 2 is rotated, the movable terminal 21 does not follow and the stopped state is maintained. The movable terminal 12 is always urged toward the terminal block 14 by a coil spring e (see FIG. 3).

  The terminal block 14 is fixed to face the movable terminal 12, and a fixed contact 15 is formed at a predetermined position. For example, when the rotor 2 moves from the off position A to the on position B, the movable contact 13 and the fixed contact 15 come into contact with each other to form a predetermined electrical circuit, and the engine 2 can be started. When the position reaches from the on position B to the off position, the movable contact 13 is separated from the fixed contact 15 so that the predetermined electrical circuit is interrupted. Thus, the movable contact 12 and the terminal block 14 constitute a switch mechanism of the ignition switch device.

  Thus, when the rotor 2 rotates from the off position A to the fuel tank open position G, a pressing operation is performed on the rotor 2, so that the engaging portion 6eb of the second cam member 6 is separated from the cross groove 12a. Thus, the engaged state is released, and the movable terminal 12 does not follow the rotation of the rotor 2. Therefore, in the process of rotating the rotor 2 in one rotational direction while pressing the rotor 2, it is possible to avoid an engine startable state, and the fuel tank can be opened exclusively.

  According to the embodiment, the first cam member 3 that rotates with the rotor 2 to operate the slide member 4 and the lock bar 5, and the second cam member that rotates with the rotor 2 to operate the seat lock actuator 8. 6 and the separate structure, the member for performing the steering lock in conjunction with the rotor 2 and the member for releasing the seat lock in conjunction with the rotor 2 can be selectively operated, Assembling property can be further improved.

  Further, the lower end portion (engagement hole 3ca) of the first cam member 3 and the upper end portion (engagement portion 6ea) of the second cam member 6 can be locked, and are locked and integrated when the apparatus is assembled. Therefore, the assembling property can be further improved. A through hole c1 is formed in the partition plate c, and a lower end portion (engagement hole 3ca) of the first cam member 3 and an upper end portion (engagement) of the second cam member 6 through the through hole c1. Part 6ea) is locked and assembled.

  Further, the second cam member 6 presses the seat locking actuator 8 by the rotation of the rotor 2 in a predetermined direction to move from the non-operating position to the operating position (first predetermined direction convex section). 6a and the second predetermined direction convex portion 6b) and the rotor 2 is rotated in the direction opposite to the predetermined direction, the operating arm 7 is swung to move the seat lock operating element 8 from the non-operating position to the operating position. The anti-predetermined direction convex portions 6c that can be protruded are formed so as to be able to release the seat lock even when the rotor 2 is rotated in the predetermined direction and the opposite direction. The attachment can be improved.

  Furthermore, a fuel tank open position G for opening the fuel tank cap of the vehicle is set at a position rotated from the off position A while being pressed in one rotational direction, and a fuel tank open mechanism for opening the fuel tank; A fuel tank opening operator 10 that is connected via a wire and can move from the non-operating position to the operating position so as to open the fuel tank and the second cam member 6 are projected and the rotor 2 is pressed. Since it has a fuel tank opening convex portion 6d that can press the fuel tank opening operating element 10 from the non-operating position to the operating position when rotating from the off position A to the fuel tank opening position G, the seat lock The cam member for operating the working actuator 8 and the cam member for operating the fuel tank opening actuator 10 are the second cam portion. 6 can be shared by, without increasing the number of parts, it is possible to perform the seat lock release and the fuel tank opening.

  The seat lock actuator 8 is provided with a coil spring 9 (biasing means) that constantly urges the seat lock actuator 8 to the non-actuated position side. Therefore, after the seat lock is released, The locking actuator 8 can be reliably returned from the operating position to the non-operating position. In particular, in the present embodiment, the seat lock operating element 8 is engaged with the operating arm 7, but even in this state, the seat lock operating element 8 is smoothly and reliably moved from the non-operating position to the operating position. It can be returned. Instead of the coil spring 9, other general-purpose urging means may be used.

  The second cam member 6 is integrally formed with a shaft portion 6e that forms the center of rotation, and the operating arm 7 is formed with a bent portion 7b so as to avoid interference with the shaft portion 6e. Therefore, the dimension between the swing center (swing axis L) of the operating arm 7 and the locking portion (locking convex portion 7a) with respect to the seat lock operating element 8 is set. It can be set long, and the seat lock actuator 8 can be operated reliably and satisfactorily.

Although the present embodiment has been described above, the present invention is not limited to this. For example, it is sufficient if it has a function of releasing the seat lock, and it does not include a mechanism for opening the cap of the fuel tank ( The fuel tank open position G, the fuel tank open operator 10, the fuel tank open convex portion 6d, etc. may not be provided) . The present invention can be applied to an ignition switch device in various vehicles other than two-wheeled vehicles.

In the rotational direction of the rotor, a seat lock release position that allows the seat to be released by releasing the seat lock of the vehicle is set, and a lock bar that locks and locks the steering shaft of the vehicle is locked. The rotor is slid by rotating while being pressed, and the lock bar protrudes, and the slide member that can be locked by steering, and the seat lock and the wire are connected to each other and operate from the non-operating position to the operating position. And a first cam member that rotates with the rotor to operate the slide member and the lock bar, and a seat lock actuator that rotates with the rotor. is a second cam member formed separately configured for operating a seat lock release position, the other from the oFF position The rotation direction, the steering lock position to the other rotation direction, and the ON position to the one rotation direction, respectively, and can be swung around one end across the radial direction of the second cam member. The second cam member presses the seat lock actuator by rotation of the rotor in a predetermined direction and has an operating position from the non-operating position. And a predetermined direction that can move the operating arm from the non-operating position to the operating position by swinging the operating arm when the rotor rotates in a direction opposite to the predetermined direction. As long as the ignition switch device is formed so that the projecting convex portions protrude from each other, it can also be applied to devices having different external shapes or those having other functions added thereto.
