In the above case, when the front wheel 4 is steered to the maximum steering angle, the side surface of the front wheel 4 is positioned with a slight gap behind the rear edge of the upper arm 14 and the protector 50. Therefore, further steering is prevented by a stopper (not shown).
[0031]
Further, the operating device 34 moves to the bracket 38 fixed to the left end portion of the bar handle main body 22 of the bar handle 21 by a pivot shaft 55, and is a parking brake operation pivotally supported so as to be able to return and rotate D and E. And a wire 57 for interlockingly connecting the second caliper 33 to the parking brake operation unit 56. The parking brake operation unit 56 is specifically a parking brake lever 58. The parking brake lever 58 extends in the width direction of the vehicle 1 in a direction (right side) opposite to the direction (left outer side) in which the clutch lever 42 extends from the base side. The lever 58 is almost entirely positioned in front of the shaft center 22a at the left end of the bar handle 21.
[0032]
When the parking brake lever 58 of the parking brake operation unit 56 is positioned as described above, the second caliper 33 is separated from the brake disk of the braking device 9 by the biasing force F of a spring (not shown). The braking device 9 is not braked. That is, the parking brake lever 58 is positioned at a position to release the braking of the parked vehicle 1 without being interlocked with the operation on the start operation unit 40. Further, as described above, parking an earlier brake lever 58 is Gana operation for braking the vehicle 1, by the biasing force F, its forward this parking brake lever 58 to the handlebar 21 via a wire 57 The parking brake lever 58 is prevented by the stopper 59 from going forward beyond a predetermined position (solid line in FIG. 1) in front of the left end portion of the bar handle 21. ing.
[0033]
On the other hand, the occupant gives an operating force for braking the vehicle 1 to the parking brake lever 58 to reversely rotate E, and extends the parking brake lever 58 from the base side (the bracket 38 side) to the left outer side. When the rear caliper E is made to be in such a posture and until it is positioned in front of the left grip 23, the second caliper 33 is frictionally joined to the brake disk of the braking device 9 and is applied to the braking device 9. There Ru allowed to braking action. That is, the parking brake lever 58 is positioned at a position where the parked vehicle 1 is braked without being interlocked with the operation of the start operation unit 40, and the vehicle 1 is put into a parking brake state.
[0034]
In the above case, when the parking brake lever 58 is rotated backward E as described above and reaches the predetermined position in front of the left grip 23 (the chain line in FIG. 1), the backward rotation E is further increased. The parking brake lever 58 is blocked by contacting a part of the bar handle 21, and the parking brake lever 58 is elastically held at the predetermined position (a chain line in FIG. 1) by the urging force F. If the parking brake lever 58 is given an operating force for releasing the braking of the vehicle 1 from the above state and the parking brake lever 58 is rotated forward D, the parking brake lever 58 returns to its original position, and again this The position is elastically held by the biasing force F (solid line in FIG. 1).
[0035]
In a plan view of the vehicle 1 (FIG. 1), the shaft centers of the pivot shafts 39 and 55 are brought close to each other and extend substantially parallel to each other. The clutch lever 42 and the parking brake lever 58 are arranged so that their trajectories are close to each other in the vertical direction and are positioned in the front area of the left end portion of the bar handle 21. Further, the parking brake lever 58 is disposed above the clutch lever 42.
[0036]
In the above case, the parking brake lever 58 of the parking brake operation unit 56 is operated to brake the vehicle 1 and is rotated backward E to reach the predetermined position (a chain line in FIG. 1). When the device 9 is braked and the vehicle 1 is put into the parking brake state, the parking brake lever 58 is in the front-rear direction from the position of the clutch lever 42 of the start operation unit 40 that is not operated (solid line in FIG. 1). Thus, the bar handle 21 is positioned closer to the left grip 23, which is the left end of the bar handle 21.
[0037]
For this reason, when the clutch lever 42 is to be operated by a hand holding the grip 23, the parking brake lever 58 gets in the way, and the clutch lever 42 is rotated backward B a little (the dashed line in FIG. 1). ) Reverse rotation B is restricted as described above. That is, in the parking braking state of the vehicle 1, the vehicle 1 is prevented from being in a state where it can start by operating the clutch lever 42.
[0038]
Accordingly, it is possible to prevent the occupant from forgetting or not knowing that the vehicle 1 is in the parking braking state and making the vehicle 1 startable and not starting. As a result of the start, it is possible to prevent an excessive load from being applied to the braking device 9 used for the braking and damaging it.
[0039]
Further, the prevention of damage to the braking device 9 described above is achieved by the relative arrangement of the clutch lever 42 and the parking brake lever 58, and no sensor or control device is required. Damage prevention is achieved with a simple configuration.
[0040]
Further, as described above , substantially the entire parking brake lever 58 of the parking brake operation unit 56 positioned at the position where the braking of the vehicle 1 is released is positioned forward of the shaft center 22a at the end of the bar handle 21. It is located in.
[0041]
For this reason, when the vehicle 1 is in a normal running state in which the parking brake is not performed, the parking braking operation unit 56 is separated from the bar handle 21 in the front-rear direction as viewed from the occupant side. Will be located. Therefore, the parking braking operation unit 56 is prevented from giving a sense of pressure to the occupant, and the riding comfort of the vehicle 1 is improved.
[0042]
Further, as described above, the start operation unit 40 includes the clutch lever 42 pivotally supported on the end portion of the bar handle 21, and the parking brake operation unit 56 is disposed above the clutch lever 42. A parking brake lever 58 is provided.
[0043]
For this reason, particularly in the buggy vehicle 1 for traveling on rough land, the occupant's knees tend to collide with each end of the bar handle 21, but as described above, the parking brake operation unit 56 is arranged on the upper side. Thus, the collision of the occupant's knees with the parking braking operation unit 56 is prevented, and the riding comfort on the vehicle 1 is improved.
[0044]
Further, as described above, the turning direction of the reverse rotation B of the clutch lever 42 when the clutch 31 is disengaged, and the forward movement of the parking brake lever 58 of the parking brake operation unit 56 when releasing the braking. The moving direction which is the movement D is opposite to each other.
[0045]
Therefore, in the parking braking state of the vehicle 1 in which the parking brake lever 58 of the parking braking operation unit 56 is operated and the braking device 9 is braked, there is no intention of starting the vehicle 1, When the clutch lever 42 is simply operated, the parking brake state of the vehicle 1 is prevented from being unintentionally released, and the vehicle 1 is maintained in the parking brake state.
[0046]
Although the above is based on the illustrated example, the transmission mechanism 30 may be configured as follows.
[0047]
That is, when the parking brake lever 58 of the parking brake operation unit 56 is operated to complete the reverse rotation E and the vehicle 1 is put into the parking brake state (a chain line in FIG. 1), the parking brake levers 58 beyond this are used. Spring-type positioning means for once restricting the backward rotation E ′. From this state, when the clutch lever 42 of the start operation unit 40 is operated to rotate backward B, and the operation force to the clutch lever 42 exceeds the regulating force of the positioning means, the clutch lever The parking brake lever 58 may be further rotated backward E ′ by the operation force 42 to return to the original position indicated by the solid line in FIG. That is, when the clutch lever 42 is operated with a large operating force, the braking device 9 may be automatically unbraking and the vehicle 1 may be ready to start.
[0048]
