The handle 72 is rotated (arrow D in FIG. 5), and the fixing by the fixing means 67 is released (the chain line in FIGS. 4 and 5), so that the base 20a of each handle 20 is rotated around the axis 65. Can be rotated. Next, the steering wheel 20 is turned to the desired position toward the center in the width direction of the vehicle body 2 so as to approach each other and folded (arrow E in FIGS. 1, 3 and 4). The base 20a may be fixed to the handle stem 66 again by the fixing means 67.
[0046]
Then, the projecting dimension when each handle 20 projects outward from the upper end side of the steering shaft 11 is reduced, so that the vehicle 1 can be reduced in size, and the transportation and the like can be facilitated. .
[0047]
Further, as described above, the locking means for restricting the rotation of the base portion 20a of each handle 20 around the axis 65 by locking the base portion 20a of each handle 20 to the handle stem 66 in a detachable manner. 77 is provided.
[0048]
For this reason, even if the fixing is loosened during traveling in a state in which the base 20a of each handle 20 is fixed to the handle stem 66 by the fixing means 67, the base 20a of each handle 20 is fixed. Unintentional rotation of the vehicle 1 is prevented by the locking means 77, so that it is possible to prevent the comfortable running of the vehicle 1 from being impaired.
[0049]
Further, as described above, if the fixing is loosened, the base 20a of each handle 20 is simply locked to the handle stem 66 by the locking means 77, and each handle 20 Since 20 has some shakiness, the looseness is immediately perceived by the rider.
[0050]
Therefore, it is possible to prevent the vehicle from traveling for a long time without knowing that the handle 20 with respect to the handle stem 66 is loosened.
[0051]
In addition, when each of the handles 20 is to be folded and the fixing is released by operating the fixing means 67, the handles 20 suddenly rotate unintentionally as the fixing is released. This is prevented by the locking means 77.
[0052]
Therefore, when releasing the fixing, it is not necessary to pay attention to preventing unintentional rotation of the handles 20, so that the operation for reducing the size of the vehicle 1 can be performed smoothly.
[0053]
Further, as described above, the base portion 20a of each handle 20 can be raised and lowered with respect to the handle stem 66, and the locking means 77 is provided with the locking member 78 provided on the handle stem 66 side and each handle. 20 is provided on the side of the base portion 20a, and is provided with a locked member 79 that is detachably locked to the locking member 78 as the base portion 20a moves up and down.
[0054]
For this reason, when each handle 20 is to be folded, in addition to releasing the fixation by operating the fixing means 67, the base 20a of each handle 20 is lifted and lowered to the handle stem 66. Release is requested.
[0055]
Therefore, when each of the handles 20 is to be folded and the fixing means 67 releases the fixation, the handles 20 suddenly rotate unintentionally as the fixation is released. The operation for reducing the size of the vehicle 1 can be performed more smoothly.
[0056]
As described above, the axis 4 of the support hole 68 formed in the handle stem 66 and the axis 65 of each fitting hole 69 are parallel to each other.
[0057]
Therefore, the support hole 68 and each fitting hole 69 can be easily formed by machining, and the productivity of the handle stem 66 is improved.
[0058]
Although the above is based on the illustrated example, the vehicle 1 may be a bicycle or a three-wheeler. The traveling drive source of the vehicle 1 may be an internal combustion engine. The internal combustion engine may be separated from the rear arm 25 and supported by the vehicle body frame 3.
