The fan-shaped part 68b formed in a fan shape with the semicircular part 68a as a main position is continuous, and one end in the circumferential direction of the fan-shaped part 68b (lower end in FIG. 9) is a side wall portion of the inner cylinder 25. It is formed as a contact locking portion 69 that can contact and engage with the engaging portion 65. Moreover the slide member 66 when the seat lock mechanism 14 remains locked state is in the position shown in Figure 9, this time, the engaging portion 65 of the inner cylinder 2 5 defined amount pushed at the OFF position P2 abutting engagement 9 enters the engagement hole 68 so as to approach and oppose the stopper 69, and the inner cylinder 25, which has been pushed by a specified amount, moves from the off position P2 to the seat lock unlocking position P3 in the clockwise direction of FIG. As shown in FIG. 12, when the engaging portion 65 comes into contact with and engages with the contact locking portion 69, the rotating member 64 rotates in the clockwise direction.

  Further, when the inner cylinder 25 that has been pushed by a predetermined amount is rotated from the off position P2 to the lock position P1 in the counterclockwise direction of FIG. 9, the engaging portion 65 is moved in the fan-shaped portion 68b with the contact locking portion 69. Is displaced to a position close to and opposite to the opposite side wall, and no force acts on the rotating member 64 from the inner cylinder 25. That is, the turning member 64 is formed in a shape that avoids engagement with the inner cylinder 25 when the inner cylinder 25 that has been pushed by a predetermined amount is turned from the off position P2 to the lock position P1 side.

  An arc-shaped wall portion 70 surrounding a part of the cylindrical portion 64a is formed on the outer peripheral portion of the flange portion 64b of the rotating member 64 so as to form an arc-shaped groove 71 between the cylindrical portion 64a. As shown clearly in FIG. 3, a torsion spring 72 that accommodates a part in the groove 71 and surrounds the cylindrical portion 64a is provided between the cylinder body 24 and the rotating member 64.

When the inner cylinder 25 between the lock position P1 and the off position P2 is pushed, the engagement portion 65 of the inner cylinder 25 is a restriction wall. The rotation restricting portion 78 can be passed without contacting the portion 77. When the push operation force to the inner cylinder 25 is released at the lock position P1, the inner cylinder 25 moves forward so that the engagement portion 65 passes through the rotation restriction portion 78 from the engagement hole 68 of the rotation member 64. It will return to the position.

  Further, when the inner cylinder 25 is rotated to the seat lock unlocking position P3 side during the push operation of less than the specified amount at the off position P2, the engaging portion 65 comes into contact with the rotation restricting portion 78, and the inner cylinder 25 Rotation to the seat lock unlocking position P3 side is restricted.

The guide recess 84 is slidably accommodated in the accommodating recess 79, and the guide projection 84 integrally projecting from the lid member 81A is fitted into the guide recess 85 provided in the slide member 64.

  On both sides of one surface of the slide member 66 facing the rotating member 64, fitting recesses 86, 86 extending in the sliding direction of the slide member 66 are provided. On the other hand, the rotating member 64 is integrally provided with a pair of arm portions 87, 87 extending from the restricting portion 74 toward the slide member 66, and the distal end portions of the arm portions 87 are the two fitting recesses. 86... Further, a projecting portion 88 having a circular cross section is integrally provided on the upper portion of the slide member 66, and a return spring 89 that is a coil spring partially surrounds the projecting portion 88. It is compressed between the upper part and the cylinder body 24. The return spring 89 exerts a spring force that urges the slide member 66 toward the side abutted against the both arm portions 87 of the rotation member 64. The slide member 66 rotates the rotation member 64. It will slide according to the movement.

  Thus, when the inner cylinder 25 is in the off position P2 and the rotating member 64 is in a state where the restricting portion 74 is in contact with the cylinder body 24 as shown in FIG. As shown in FIG. 11, when the inner cylinder 25 which is at the lower limit position and has been pushed by a specified amount is turned from the off position P2 to the seat lock unlocking position P3, the turning member 64 is turned as shown in FIG. When pivoting in the direction, the slide member 66 is displaced to the upper limit position against the spring force of the return spring 89 so that the projection 88 abuts the cylinder body 24.

  The cable 15 is a push-pull cable in which the inner cable 91 is movably inserted into the outer cable 90, and a support tube 92 provided at one end of the outer cable 90 is provided integrally with the lid member 81A. It is engaged with a support plate portion 93 located below the cylinder body 24.

The stop piece 101 is accommodated in the guide recess 85 of the slide member 66 so as to contact and engage the inner surface of the lower end wall. That is, the connecting portion of the slide member 66 and the cable 15 is disposed in the cylinder body 24 on the side of the mounting surface 80 to the head pipe 18 so as to be sandwiched between the cylinder body 24 and the head pipe 18 of the vehicle body.

  The locking piece 101 is formed in a short cylindrical shape, and one end of the inner cable 91 is fixed to the central portion in the longitudinal direction of the locking piece 101. Thus, the slide member 66 at the lower limit position in the locked state of the seat lock mechanism 14 responds to the rotation operation of the inner cylinder 15 that has been pushed by the specified amount at the off position P2 to the seat lock unlock position P3. In accordance with the rotation of the rotating member 64, the upper member is displaced to the upper limit position as shown in FIG. 12, and the cable 15 is moved from the slide member 66 to the cable 15 in accordance with the slide operation of the slide member 66. An operating force that pulls 15 is applied, and thereby the seat lock mechanism 14 is unlocked.

  A slit 99 is provided in the cylinder body 24 and the lid member 81A for inserting one end of the inner cable 91 in a state where the locking piece 101 is brought into contact with and engaged with the slide member 66, and the slide member An insertion groove 100 connected to the slit 99 is provided in the lower end wall of the member 66 so that one end of the inner cable 91 can be inserted therethrough.

  Incidentally, in order to easily engage and connect the locking piece 101 to the slide member 66, the locking piece 101 fixed to one end of the inner cable 91 in the cable 15 acts on the cable 15 from the slide member 66. Therefore, the slide member 66 is moved from the position offset from the slide member 66 in a direction different from the direction in which the operating force is applied, and is engaged with and connected to the slide member 66.

  That is, the lid member 81A is provided with an insertion hole 103 (see FIG. 9) through which the locking piece 101 can be penetrated at a position offset laterally from the housing recess 79, and the cylinder body 24 is provided with the insertion hole 103. The slide member 66 is provided with a connecting groove 105 connecting the insertion recess 104 and the guide recess 85 at the lower limit position thereof. Thus, the locking piece 101 inserted into the insertion recess 104 from the insertion hole 103 is displaced toward the slide member 66 at the lower limit position so that the locking piece 101 is accommodated in the guide recess 85 and contacts the slide member 66. Can be engaged.

  The lid member 81 </ b> A is provided with a slit 106 corresponding to the connecting groove 105 for moving one end of the inner cable 91 when the locking piece 101 is moved from the insertion recess 104 toward the slide member 66. It is done.

  Next, the operation of the first embodiment will be described. The inner cylinder 25 has a switch connecting shaft portion 25d that is capable of axial relative movement within a limited range and is connected to the ignition switch 20 so as not to be relatively rotatable, and The cam portion 25b that constitutes a part of the steering lock mechanism 19 is integrally provided, and the engaging portion 65 is integrally provided. The inner cylinder 25 rotates from the off position P2 to the seat lock unlocking position P3. When operating, a rotating member that is inserted and supported in the cylinder body 24 so as to require a specified amount of push operation before the rotating operation, and constitutes a part of the operating force output mechanism 63 64 has an abutment locking portion 69 that can abut and engage the engaging portion 65 in response to a push operation of a specified amount at the off position P2, and It is rotatably supported in 25.

  Therefore, an on / off function of the ignition switch 20, a steering lock function, and an operation force output function to the seat lock mechanism 14 can be obtained with a simple configuration with a reduced number of parts. Further, the rotating member 64 constituting a part of the operating force output mechanism 63 is rotatably supported by the inner cylinder 25, and the engagement portion 65 of the inner cylinder 25 and the rotating member 64 abut on each other. The relative arrangement with the locking portion 69 can be determined with high accuracy, and reliable contact and engagement are possible.

  Further, the cylinder body 24 is provided with a rotation restricting portion 78 that abuts the engaging portion 65 and prevents the inner cylinder 25 from rotating toward the seat lock unlocking position P3 when the push operation is less than the specified amount at the off position P2. Therefore, when the inner cylinder 25 is reliably pushed by a specified amount at the off position P2, the engaging portion 65 of the inner cylinder 25 can be brought into contact with and engageable with the contact locking portion 69 of the rotating member 64. Unless this is the case, the rotation restricting portion 78 prevents the inner cylinder 25 from rotating toward the seat lock unlocking position P3. Accordingly, the rotating member 64 can be rotated.

  Further, the seat lock unlocking position P3 is set between the off position P2 and the on position P4, and the inner cylinder 25 is released between the cylinder body 24 and the inner cylinder 25 when the inner cylinder 25 is pushed by a specified amount. Since the first restricting means 51 for preventing the lock position P3 from turning to the on position P4 side is provided, the inner cylinder 25 is moved to the seat lock unlocking position P3 when the inner cylinder 25 is pushed at the off position P2. Is prevented from turning to the on position P4 side, and the ignition switch 20 is not turned on undesirably when the operating force is output to the seat lock mechanism 14, and the power consumption of the battery increases. I don't have to.

  The inner cylinder 25 is inserted and supported in the cylinder body 24 in such a manner that a predetermined amount of push operation is required before the turning operation when turning from the off position P2 to the lock position P1. The moving member 64 is formed in a shape that avoids engagement with the inner cylinder 25 when the inner cylinder 25 that has been pushed by a specified amount is rotated from the off position P2 to the lock position P1 side. When the inner cylinder 25 that has been pushed is rotated to the lock position P1 side, the rotation of the inner cylinder 25 is not transmitted to the rotation member 64, and only the steering lock mechanism 19 can be operated reliably. it can.

  Further, between the cylinder body 24 and the inner cylinder 25, the second restricting means 52 for restricting the turning end of the inner cylinder 25 on the lock position P1 side, and the inner cylinder 25 turning to the lock position P1 side at the off position P2. Are provided, and the third restricting means 53 for restricting the rotation end of the inner cylinder 25 on the ON position P4 side is provided, so that the switch connecting shaft portion 25d, the cam portion 25b, and the engaging portion are provided. The second to fourth restricting means 52 to 54 provided between the inner cylinder 25 and the cylinder body 24 integrally having 65 are used to securely determine the lock position P1, the off position P2, and the on position P4 to turn on the ignition switch 20. The structure for switching between the off / off function and the steering lock function can be configured in a compact manner.

  In addition, the connecting portion of the slide member 66 and the cable 15 constituting a part of the operating force output mechanism 63 is sandwiched between the cylinder body 24 and the head pipe 18 of the vehicle body, so that the cylinder body 24 on the mounting surface 80 side to the vehicle body. Since the cylinder body 24 is mounted on the vehicle body side, the connecting portion of the slide member 66 and the cable 15 is covered with the cylinder body 24 and the head pipe 18 of the vehicle body. The connection state of the slide member 66 and the cable 15 can be maintained by preventing unauthorized access to the connection part of the cable 66 and the cable 15, and the locked state of the seat lock mechanism 14 is prevented from being undesirably released. be able to.

  Further, the locking piece 101 fixed to one end of the cable 15 moves from the position offset from the slide member 66 to the slide member 66 side in a direction different from the direction of operation of the operating force acting on the cable 15 from the slide member 66. Since the slide member 66 is engaged and connected, a special member for connecting the cable 15 to the slide member 66 is not necessary, and the number of parts is reduced, and the connection of the cable 15 is released by the slide operation of the slide member 66. In this way, the cable 15 can be connected to the slide member 66.
