  In such a stand device, as shown in FIG. 2, in the parking state in which the stand 41 is rotated to the upright position at the lower limit rotation position of the stand support member 36, the rotation lock means 55 is used unless the operation lever 45 is operated. The lower limit rotation position of the stand support member 36 is held, the stand 41 is held by the weight of the motorcycle, and the motorcycle has a posture in which the front wheel WF is floated from the ground.

  To release the parking state, as shown in FIG. 6, when the storing operation is performed by depressing the operating lever 45, the control lever 56 rotates against the spring force of the coil spring 58 by pulling the cable 64. Accordingly, the engagement arm 47 rotates to the side where the engagement portion 47a is detached from the locking recess 48, and the rotation lock means 55 rotates the stand support member 36 upward from the lower limit rotation position. The stand support member 36 is rotated upward by the pulling of the cable 64 in a state where the engagement arm 47 and the control lever 56 are in contact with each other, and the front wheel WF is grounded.

  When the operation lever 45 is further pushed down and the stand support member 36 is rotated upward until the stand 41 is lifted from the ground as shown in FIG. 7, the stand 41 is moved by the stand biasing spring 44 as shown in FIG. The storage position of the stand 41 is held by rotating from the standing position to the retracted position around the axis of the stand shaft 40 by the spring force and coming into contact with the second stopper 73 provided at the right end of the second bracket 39. . If the hand is released from the operation lever 45 in this state, the stand support member 36 rotates downward around the axis of the first support shaft 34 as shown in FIG. 9 by its own weight and returns to the lower limit rotation position. The lever 45 returns to the upper original position. At this time, the rotation lock means 55 is in a locked state in which the engagement portion 47a is engaged with the engagement recess 48, and the lower limit rotation position of the stand support member 36 is held.

  When the stand 41 is grounded to obtain the parking state, the stand 41 may be rotated from the storage position to the standing position side with the stand support member 36 in the lower limit rotation position as shown in FIG. 10, after the stand 41 is grounded, the vehicle body is moved rearward so that the front wheel WF is lifted by placing the foot on the footrest portion 42f of the stand 41, and the stand device is shown in the state shown in FIG. 2 state.

  By the way, in a state in which the operation lever 45 does not perform the storage operation, that is, in a state in which the stand support member 36 remains at the lower limit rotation position, the rotation of the stand 41 from the standing position to the storage position is performed by the storage restriction cam 75. Is prevented by.

  The storage regulating cam 75 is formed at the lower end of the engagement arm 47 when the stand 41 is rotated from the standing position to the storage position side with the engagement arm 47 in the locked position. By being in contact with the contact surface 47 b, the stand 41 is provided on the stand 41 so as to restrict the rotation of the stand 41 toward the storage position, and the fourth support shaft 76 is provided on the left support plate 43 of the stand 41. A spring 77 is provided between the storage regulating cam 75 and the support plate 43 so as to be pivotably supported via the spring and biasing the storage regulating cam 75 on the side abutting on the abutting surface 47b.

  Thus, the storage regulating cam 75 is in contact with the contact surface 47b of the engagement arm 47 as shown in FIG. 2 when the operation lever 45 is parked in the non-storage operation state. Unless the stand 45 is retracted and the stand support member 36 is not rotated upward from the lower limit rotation position, the rotation of the stand 41 toward the storage position is prevented by the contact of the storage regulating cam 75 with the contact surface 47b. Is done. On the other hand, when the operation lever 45 is retracted and the stand support member 36 is rotated upward from the lower limit rotation position, the engagement arm 47 retracts the engagement surface 47b as shown in FIGS. Since it rotates to the position which cancels | releases contact with the control cam 75, rotation to the retracted position of the stand 41 is permitted. On the other hand, when the stand 41 is rotated from the retracted position to the standing position, the stand support member 36 is at the lower limit rotation position. The storage restricting cam 75 comes into contact with the lower end of the engaging arm 47 from below, but the storage restricting cam 75 gets over the lower end of the engaging arm 47 while reducing the spring 77, and as shown in FIG. Further, the storage regulating cam 75 biased by the spring 77 abuts on the abutment surface 47 b of the engagement arm 47.

  Further, when the engagement arm 47 is in the locked position where the engagement portion 47a is engaged with the engagement recess 48 of the fixed engagement portion 46 (the state shown in FIG. 2), the storage restriction cam 75 Although the direction 78 of action of the pressing force on the engagement arm 47 is substantially the same as the direction of rotation of the point of action of the pressing force when the engagement arm 47 is rotated from the locked position to the unlocked position, The rotation lock means 55 regulates the rotation of the engagement arm 47 from the lock position to the unlock position even by a pressing force action from the engagement arm 47 when the operation lever 45 is not retracted. Configured as follows. In other words, in this embodiment, the connection link 57 extends in parallel with the direction in which the pressing force is applied, and acts on the control lever 56 from the storage restriction cam 75 via the engagement arm 74 and the connection link 57. The rotation lock means 55 is configured so that the force acts on the control lever 56 on the side where the engaging portion 47 a of the engaging arm 47 is engaged with the engaging recess 48.

  The control lever 56 is provided with an arm abutting portion 56b that abuts the engaging arm 47 from the side opposite to the fixed locking portion 46 when the lever 45 is not retracted. A contact point of the contact portion 56b with the engagement arm 47 and a straight line L3 (see FIG. 2) connecting the rotation axis of the control lever 56, that is, the center of the third support shaft 59, are from the lock position of the engagement arm 47. It is set so as to substantially coincide with the rotation direction of the contact point when rotating to the unlock position.

  Furthermore, when the engagement arm 47 is in the unlock position, the angle α formed by the engagement arm 47 and the connecting link 57 is less than a right angle in a state where the stand support member 36 is rotated upward from the lower limit rotation position. A restricting surface 79 for restricting the rotation of the engagement arm 47 is provided on the vehicle body frame F side so as to avoid it. In this embodiment, the restricting surface 79 is provided on the front surface of the locking member 49 fixed to the vehicle body frame F. The restriction surface 79 is formed so as to be able to come into contact with the engagement arm 47.

  That is, when the traction force acting on the cable 64 is released in a state where the stand support member 36 is rotated upward from the lower limit rotation position, the engagement arm 47 is moved to the arm of the control lever 56 as shown in FIG. A state may occur in which the engagement arm 47 and the control lever 56 are relatively rotated away from the contact portion 56b. At this time, the engagement arm 47 is engaged with the engagement recess 48 of the fixed engagement portion 46. When the control lever 56 is rotated downward to the position shown in FIG. 9 and the angle α formed by the engagement arm 47 and the connection link 57 is equal to or less than a right angle, the control is performed by the connection link 57. The rotation of the arm 56 and the engagement arm 47 is restricted, and the stand support member 36 cannot return to the lower limit rotation position. However, when the engagement arm 47 is in the unlock position, the engagement arm 47 is brought into contact with the restriction surface 79 as shown by the chain line in FIG. 12 even when the stand support member 36 is in the upper limit rotation position. When the stand support member 36 is pivoted upward from the lower limit pivot position when is in the unlocked position, the angle α formed by the engagement arm 47 and the connecting link 57 is avoided to be less than a right angle. A regulating surface 79 that regulates the rotation of the combined arm 47 is formed on the front surface of the locking member 49.

  In addition, in the parking state in which the stand support member 36 is set to the lower limit rotation position and the stand 41 is set to the standing position, the engagement position of the engagement arm 47 to the fixed locking portion 46 and the arm contact portion 56b of the control lever 56 are set. As shown in FIG. 2, the point of contact with the engagement arm 47 is covered from the outside by the left arm portion 36a of the arm portions 36a, 36a of the stand support member 36 in a side view.

  Next, the operation of this embodiment will be described. The stand support member 36 that rotates upward in conjunction with the retracting operation of the operation lever 45 can be turned up and down to the main frame pipe 12 of the vehicle body frame F. The stand 41 supported and capable of obtaining a parking state when the stand support member 36 is rotated to the upright position at the lower limit rotation position enables the rotation between the upright position and the storage position. The member 36 is pivotally supported so as to be rotatable.

  Therefore, when the operation lever 45 is retracted in a parking state where the stand 41 is in the standing position while the stand support member 36 is at the lower limit rotation position, the stand support member 36 is rotated upward. The pivotally supported stand 41 is also lifted away from the ground together with the stand support member 36, so that the vehicle weight applied to the stand 41 in the parked state does not affect the storing operation, and a small operating force The parking state can be canceled and the stand 41 can be stored.

  The main frame pipe 12 of the vehicle body frame F is provided with a fixed locking portion 46, and the stand support member 36 is engaged with the fixed locking portion 46 so that the stand support member 36 is at the lower limit rotation position. Rotation between the lock position to be held and the unlock position to release the engagement with the fixed locking portion 46 so that the stand support member 36 can be rotated upward from the lower limit rotation position. The engagement arm 47 is supported, and the rotation lock means 55 sets the engagement arm 47 in the lock position to the unlock position when the operation lever 45 is retracted. Since the rotation position of 47 is switched in conjunction with the operation of the operation lever 45, the stand support member is parked by the rotation lock means 55 that operates according to the operation of the operation lever 45. Will be the lower limit turned position of 6 is maintained, the parking state of the motorcycle can be reliably maintained.

  In addition, since the stand urging spring 44 that urges the stand 41 toward the storage position is provided between the stand support member 36 and the stand 41, the stand 41 can be moved when the stand support member 36 is turned upward from the parking state. The spring force of the urging spring 44 rotates from the standing position to the storage position, so that no complicated operation is required to store the stand 41, and the storage operation is further facilitated.

  The operating lever 45 is supported so as to be able to swing up and down on the vehicle body frame F so as to be pushed down when the stand 41 is stored. When the stand 41 is stored, the operating lever 45 may be pressed down. The force required for the storing operation is smaller than that for pushing up, and the storing operation becomes easier.

  Further, when the operation lever 45 is not in the retracted operation state, the rotation of the stand 41 to the retracted position is restricted by the storage restricting cam 75, so that the stand 41 can be lifted even if the motorcycle is lifted without the operation lever 45 being retracted. Does not rotate to the retracted position, and the work involving lifting of the motorcycle with a crane or the like is facilitated.

  In addition, the storage regulating cam 75 abuts against the engagement arm 47 when the stand 41 rotates from the standing position to the storage position side with the engagement arm 47 in the locked position. Is provided in the stand 41 so as to restrict the rotation of the storage 41 toward the storage position. When the stand 41 is rotated from the standing position toward the storage position, the storage restriction cam 75 is moved to the engagement arm 47. Since the rotation of the stand 41 toward the storage position side is restricted by the contact, the storage restriction and release of the stand 41 can be accurately performed with a simple structure.

  In addition, the direction 78 of action of the pressing force from the storage restricting cam 75 on the engagement arm 47 at the lock position is such that the pushing force when the engagement arm 47 is rotated from the lock position to the unlock position. Although it substantially coincides with the rotation direction of the pressure application point, the engagement arm 55 is also operated by the pressing force from the engagement arm 47 when the operation lever 45 is not retracted. 47 is configured to restrict the rotation of the 47 from the locked position to the unlocked position, and therefore the direction of action of the pressing force from the storage regulating cam 75 on the engaging arm 47 at the locked position is engaged. Even if the operating direction of the pressing force when the arm 47 is rotated to the unlock position side substantially coincides with the rotational direction, the retracting operation of the stand 41 can be reliably restricted.

  Further, the rotation lock means 55 has a cable connecting portion 56 a connected to the operation lever 45 and is rotatably supported by the stand support member 36, and the control lever 56 is rotated. A link link 57 for connecting the control lever 56 and the engagement arm 47 so as to rotate the engagement arm 47 in conjunction with each other, and the engagement arm is in a non-retracting operation state of the operation lever 45. 47, an arm contact portion 56b that contacts from the side opposite to the fixed locking portion 46 is provided on the control lever 56. The contact point of the arm contact portion 56b with the engagement arm 47 and the control lever 56 are provided. A straight line L3 connecting the rotation axes of the engagement arms 47 is set so as to substantially coincide with the rotation direction of the contact point when the engagement arm 47 is rotated from the lock position to the unlock position. In, it is possible to more reliably restrict the operation of storing the stand 41 by a simple structure of the rotary locking means 55.

  Further, when the stand support member 36 is rotated upward from the lower limit rotation position with the engagement arm 47 in the unlock position, the angle α formed by the engagement arm 47 and the connection link 57 is equal to or less than a right angle. A restricting surface 79 for restricting the rotation of the engagement arm 47 is provided on the vehicle body frame F side so that the angle α formed by the engagement arm 47 and the connecting link 57 is equal to or less than a right angle. Therefore, the stand support member 36 can be smoothly rotated.

  Further, when the stand support member 36 is in the lower limit rotation position and the stand 41 is in the standing position, the engagement position of the engagement arm 47 with the fixed locking portion 46 and the arm of the control lever 56 are set. Since the contact point of the contact portion 56b with the engagement arm 47 is covered from the outside by the stand support member 36 in a side view, the parking state is undesirably released due to mischief or the like. Providing a separate member can be prevented as unnecessary.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various design changes can be made without departing from the present invention described in the claims. It is.

  For example, the present invention can also be applied to motorcycles other than the scooter type, motor tricycles, and bicycles.
