It is transmitted to the rotating member 131 via the spring 133, and the engaging member 124 engages with one of the locking tooth portions 126 on the outer periphery of the rotating member 123 to prevent the rotating member 123, that is, the rear wheel WR from rotating. The When the operation lever 76 is rotated to the storage position side, as shown in FIG. 12, the third rotation shaft 129 is rotated clockwise, and the engagement member 124 is a locking tooth portion on the outer periphery of the rotation member 123. The engagement with one of 126... Is released, and the rotation of the rotating member 123, that is, the rear wheel WR is allowed.

  By the way, this scooter type motorcycle is equipped with a kick starter 135. The kick starter 135 includes a kick shaft 136 rotatably supported on an outer case 39 of the transmission case 35, and the outer case 39. A kick pedal 137 that is fixed to the end of the kick shaft 136 protruding from the spring, a spring 138 that is provided between the kick shaft 136 and the outer case 39, a worm wheel 139 that is fixed to the inner end of the kick shaft 136, A worm gear 140 that meshes with the worm wheel 139 and is movable in an axial direction parallel to the kick shaft 136, a connecting member 141 fixed to the worm gear 140, and fixed to the crankshaft 26 so as to face the connecting member 141. Engaging member 142, and the connecting portion is operated by depressing the kick pedal 137. 141 in which rotating power for starting is transmitted to the crankshaft 26 by rotating advances to a position to engage the engaged member 142.

  Thus, the start of the engine E by the kick starter 135 is disabled by the kick start disable means 144 when the rear wheel lock mechanism 125 is unlocked. It is linked to and connected to the lock mechanism 125.

  The lock start impossible means 144 engages with a locking groove 143 provided in the connecting member 141 to prevent the connecting member 141 from rotating, and releases the engagement with the locking groove 143 to connect the connecting member 141. The engaging lever member 145 is rotatably supported on the outer case 39 via the shaft 146 so that the rotation permitting state can be switched, and the engaging lever member 145 is engaged with the locking groove 143. The torsion spring 147 provided between the engagement lever member 145 and the outer case 39 by exerting a spring force, and the engagement lever member 145 and the third rotation lever 129 to restrict the rotation position of the engagement lever member 145. And a connecting rod 148 for connecting the other ends of the two.

  According to such a lock start impossible means 144, when the operation lever 76 is turned to the upright position side, as shown in FIG. 11, the third turning lever 129 is turned counterclockwise. The engagement lever member 145 is rotated to a position where the engagement with the locking groove 143 is released, and the engine E can be started by the kick starter 135. When the operation lever 76 is rotated to the storage position side, as shown in FIG. 12, the engaging lever member 145 is engaged with the engaging groove 143 in accordance with the third rotating shaft 129 rotating clockwise. The engine E is turned off by the kick starter 135 so that the engine E cannot be started.

  Next, the operation of the first embodiment will be described. When the manually operable operation lever 76 is turned to the standing position side, the stand 75 is turned from the retracted position to the first standing position by the interlocking means 77. The interlocking means 77 includes a coiled stand spring 86 having one end connected to a stand 75 rotatably supported by a support case 70 attached to the vehicle body frame 15, and the other end of the stand spring 86. A spring support coupled to and connected to the operation lever 76, having a second connection pin 87 to be connected to one end and allowing the position of the second connection pin 87 to be changed in response to manual operation of the operation lever 76. The other end of the spring support member 88 is rotatably supported by the support case 70, and the operation lever 76 is moved to the upright position side. The position of the second coupling pin 87 which is determined according to the operation is set to a state in which the stand spring 86 biases the stand 75 in the standing position.

  Therefore, it is possible to rotate the stand 75 from the retracted position to the upright position using the spring force of the stand spring 86, and to operate the spring support member 88 so as to change the position of the second connecting pin 87. Since the operation force is small, the stand 75 can be rotated to the standing position side while suppressing the operation load.

  Further, the interlocking means 77 is a standing operation force transmission means 90 that transmits a manual operation force of the operation lever 76 to the side that rotates the stand 75 from the retracted position to the standing position side, to the spring support member 88 side, And a storage operation force transmission means 89 for transmitting a manual operation force of the operation lever 76 from the standing position to the side where the stand 75 is rotated to the storage position side, to the spring support member 88 side. The position of the second connecting pin 87 determined according to the operation of the 76 toward the storage position is set so that the stand spring 86 biases the stand 75 toward the storage position.

  Accordingly, the stand 75 is moved from the retracted position to the raised position according to the manual operation of the operation lever 76 with a simple configuration in which only the standing operation force transmitting means 90 and the retracting operation force transmitting means 89 are added and the operation load is kept small. It can be rotated and can be rotated from the standing position to the storage position side.

  The interlocking unit 77 includes a second rotation lever 91 that rotates about an axis parallel to the rotation axis of the spring operation member 88 in response to a manual operation of the operation lever 76 toward the storage position. Since a transmission mechanism 93 for transmitting the rotational force of the first rotation lever 91 to the spring support member 88 is provided between the other end of the support member 88 and the first rotation lever 91, a part of the interlocking unit 77. It is possible to increase the degree of freedom in arrangement of the first rotation lever 91 constituting the. In addition, if the transmission mechanism 93 provided between the other end of the spring support member 88 and the first rotation lever 91 is provided with an acceleration or deceleration function, the operation adjustment width of the stand 75 is improved and design freedom is increased. Can do.

  In addition, since the shock absorber 107 is provided between the stand 75 and the vehicle body frame 15, the rotation of the stand 75 by the stand spring 86 can be moderated to reduce noise.

  By the way, the locus LL drawn by the connection point of the stand spring 86 to the stand 75 according to the rotation of the stand 75 and the connection point of the end of the stand spring 86 to the stand 75 when the stand 75 is in the standing position. In addition, a straight line L1 connecting the centers of the second connecting pins 87 when the stand 75 is in the retracted position, a connection point to one end of the stand spring 86 when the stand 75 is in the retracted position, and the stand 75 is raised. The rotation center of the spring support member 88, that is, the first rotation shaft 94 is arranged in a region surrounded by the straight line L <b> 2 connecting the centers of the second connecting pins 87 when in the position. Thereby, a time difference can be set between the time when the operation of the operation lever 76 is completed and the time when the rotation of the stand 75 is started, so that the stand 75 is not maintained unless the operation completion state of the operation lever 76 is maintained by the time difference. Therefore, the operator's will of operation can be more reflected, and the rotation of the stand 75 against the operator's will can be suppressed.

  A one-way clutch 109 having an outer ring 108 is attached to a stand shaft 82 that is fixed to the stand 75 and rotatably supported by the support case 70, and the outer ring is in a state where the stand 75 is in the first standing position. The one-way clutch 109 prevents rotation of the outer ring 108 by the clutch operation control unit 110 in a state where the stand 75 is in the first standing position. Thus, the stand 75 is prevented from rotating toward the retracted position. Therefore, the stand 75 is rotated toward the first standing position with a simple configuration using the one-way clutch 109 and the clutch operation control means 110. Rotation of the moved stand 75 to the storage position side can be stopped in a stepless manner, and a reliable detent effect can be obtained.Therefore, not only parking with the front wheel WF and the rear wheel WR in contact with the ground is possible, but also a reliable parking state can be maintained without being affected by fluctuations in the air pressure of the wheels due to passengers getting on or getting off. Moreover, since a general one-way clutch 109 is used without using special parts, an increase in cost can be suppressed.

  Further, the clutch operation control means 110 has a plurality of locking tooth portions 111 provided on the outer periphery of the outer ring 108 at equal intervals, and positions and engagements selectively engaged with one of the locking tooth portions 111. The engagement claw 112 that enables the operation between the positions where the engagement is released is provided, and the clutch operation control means 110 can be configured with a simple structure.

  Moreover, when the stand 75 is rotated by manual operation of the operation lever 76, it is difficult to grasp the position of the stand 75, but the rotation of the stand 75 to the storage position side can be regulated in a stepless manner. By using the one-way clutch 109, the certainty of the turning operation of the stand 75 can be improved.

  Further, since the second rotating shaft 95 constituting a part of the interlocking means 77 is connected to the engaging claw 112 via the lost motion mechanism 116, the operation of the operating lever 76 for rotating the stand 75 is related. The operation of the joint claw 112 is not affected, and both the rotation operation of the stand 75 and the operation of the engagement claw 112 can be reliably performed.

  Also, a rotating member 123 that is linked and connected to the rear wheel WR, a locked state that engages with the rotating member 123 to prevent the rotation of the rear wheel WR, and an unlocked state that releases the engagement with the rotating member 123. And a rear wheel locking mechanism 125 having a switchable engaging member 124, and the engaging member 124 is interlocked and connected to a second rotating lever 92 constituting a part of the interlocking means 77, and the rotating member Since the rotation of 123 is prevented in conjunction with the rotation of the stand 75 toward the standing position, the rotation of the rear wheel WR is prevented when the scooter type motorcycle is parked with the stand 75 as the standing position. Thus, the scooter type motorcycle can be prevented from starting undesirably when the stand 75 is raised. In addition, compared with the one in which the brake mechanism is operated in conjunction with the rotation of the stand 75, the amount of play of the brake mechanism and the thickness of the brake pad are reduced, so that the stand 75 is operated between the standing operation and the brake operation. There will be no madness, and there will be no impact on the operability of each, so maintenance will be easy.

  In addition, since the lost motion mechanism 130 is interposed between the second rotation lever 92 and the engagement member 124, the operation of the operation lever 76 that rotates the stand 75 is affected by the operation of the engagement member 124. Rather, both the turning operation of the stand 75 and the operation of the engaging member 124 can be reliably performed.

  The kick starter 135 attached to the engine E is provided with a kick start impossible means 144 that interlocks with the rear wheel lock mechanism 125 so that the engine E cannot be started when the rear wheel lock mechanism 125 is unlocked. Since the kick start of the engine E is enabled only when the rotation of the wheel WR is blocked by the rear wheel lock mechanism 125, the scooter type motorcycle does not move at the time of kick start, and the operability of kick start Will improve.

  The kick starter 135 includes a connecting member 141 that moves in the crankshaft direction of the engine E and engages with the crankshaft 26 at the time of kick start, and the kick start impossible means 144 is engaged with the connecting member 141. Since the engaging lever member 145 which can disable the movement of the connecting member 141 is provided, the kick starting is impossible as a simple structure for merely engaging the engaging lever member 145 with the connecting member 141 of the kick starting device 135. The means 144 can be configured compactly.

  Further, since the rear wheel lock mechanism 125 is housed in the transmission case 35 provided in the power unit P, the power unit P can be configured compactly including the rear wheel lock mechanism 125.
