next, a connection structure for connecting the front wheel side vehicle body 110 and the rear wheel side vehicle body 120 will be described.

as shown in fig. 4 to 6, each side member 122a of the rear wheel side frame 121 is formed with a 1 st substantially U-shaped recess (1 st engaging portion) 121a that opens toward the vehicle front, and is formed with a 2 nd substantially U-shaped recess (3 rd engaging portion) 121b that is disposed further toward the vehicle front than the 1 st recess 121a and opens downward. The 1 st recessed portion 121a is a portion where the 1 st cross member 113a of the front wheel side frame 111 is engaged, and the 2 nd recessed portion 121b is a portion where the 2 nd cross member 113b of the front wheel side frame 111 is engaged (see fig. 9).

More specifically, as shown in fig. 7, the 1 st cross member 113a of the front wheel-side frame 111 is placed in the pair of 1 st concave portions 121a in a state in which the rear wheel-side vehicle body 120 is tilted rearward about the rotation axis 20a of the rear wheel 20, compared to a state in which the rear wheel-side vehicle body 110 is connected. In this state, since the 1 st recessed portion 121a is opened diagonally upward, the 1 st cross member 113a of the front wheel-side vehicle body 110 is less likely to fall off from the 1 st recessed portion 121 a.

Here, as shown in fig. 11, the 1 st recess 121a has a pair of side surfaces 121c and a bottom surface 121 d. Therefore, as shown in fig. 7, the side surface 121c and the bottom surface 121d disposed on the lower side, or the side surface 121c abuts from below the 1 st beam 113a entering the 1 st recess 121a in a state of being opened obliquely upward. That is, the 1 st recess 121a has the lower contact portion LC which contacts the 1 st cross beam 113a from below as described above. In this case, the 1 st recess 121a further includes a front contact portion FC disposed at a position further toward the vehicle front side than the lower contact portion LC and at a position higher than the lower contact portion LC. By having the front side contact portion FC, the 1 st cross member 113a of the front wheel side vehicle body 110 is less likely to fall out of the 1 st recessed portion 121 a.

After the state is achieved, as shown in fig. 8 and 9, when the rear wheel-side vehicle body 120 is tilted toward the vehicle front side about the rotation axis 20a of the rear wheel 20, the 2 nd cross member 113b of the front wheel-side frame 111 enters the pair of 2 nd concave portions 121b from below. Thus, the movement of the 1 st cross member 113a in the vertical direction with respect to the rear wheel side frame 121 is restricted by the pair of side surfaces 121c of the 1 st concave portion 121a shown in fig. 11, and the movement of the 2 nd cross member 113b in the upward direction with respect to the rear wheel side frame 121 is restricted by the bottom surface 121f of the 2 nd concave portion 121b shown in fig. 11. Further, the movement of the 2 nd cross member 113b in the front-rear direction with respect to the rear wheel side frame 121 is restricted by the pair of side surfaces 121e (see fig. 11) of the 2 nd recessed portion 121b or the pair of side surfaces 121e of the 2 nd recessed portion 121b and a coupling lock member 127 described later. In this way, the front wheel side vehicle body 110 and the rear wheel side vehicle body 120 are coupled. Further, the movement of the 1 st cross member 113a rearward with respect to the rear wheel side frame 121 is also regulated by the bottom surface 121d of the 1 st recessed portion 121 a.

As shown in fig. 4 and 6, the rear wheel side frame 121 is provided with a coupling lock member 127 that tilts about a tilting axis 127c extending in the vehicle width direction. One end side of the coupling lock member 127 is supported by the pair of side members 122a, any one of the plurality of cross members 124a to 124c, the support frame 125, and the like, and the coupling lock member 127 tilts about the tilt axis 127 c. In the present embodiment, the coupling lock member 127 is disposed on the inner side in the vehicle width direction than the pair of 2 nd recessed portions 121b provided in the pair of side members 122a in the vehicle width direction.

The coupling lock member 127 is biased by a biasing member 127d such as a torsion spring so that the other end side of the coupling lock member 127 tilts rearward. Further, when the coupling lock member 127 is tilted rearward by the biasing member 127d, a part of the coupling lock member 127 or a member fixed to the coupling lock member 127 abuts a part of the rear wheel side frame 121, and the coupling lock member 127 is not tilted to a position on the vehicle rear side of the abutting position.

the coupling lock member 127 is formed with a projecting portion 127a projecting rearward, and when the coupling lock member 127 is tilted rearward by the biasing member 127d and is disposed at the lock position a shown by the solid line in fig. 6, the projecting portion 127a abuts against the 2 nd cross member 113b entering the 2 nd recessed portion 121b from below. Therefore, the engagement between the 2 nd cross member 113b and the 2 nd concave portion 121b is maintained by the coupling lock member 127. That is, the coupling between the front wheel side vehicle body 110 and the rear wheel side vehicle body 120 is maintained by the coupling locking member 127. When the coupling lock member 127 is disposed at the lock position a, as shown in fig. 11, a part of the protrusion 127a (a part of the vehicle rear side) is disposed at a position further toward the vehicle rear side than the vehicle rear side surface 121e out of the pair of side surfaces 121e of the 2 nd recess 121 b.

In the present embodiment, the connection means a state in which the 2 nd cross member 113b is engaged with the 2 nd concave portion 121b, and the front wheel side vehicle body 110 and the rear wheel side vehicle body 120 are connected in a state in which they can travel. That is, such coupling is maintained by the coupling locking member 127.

On the other hand, when the coupling lock member 127 is tilted toward the vehicle front and disposed at the retracted position B shown in fig. 6, the projecting portion 127a is not in contact with the 2 nd cross member 113B, and the coupling between the front-wheel-side vehicle body 110 and the rear-wheel-side vehicle body 120 can be released or the coupling between the front-wheel-side vehicle body 110 and the rear-wheel-side vehicle body 120 is released.

Further, an inclined surface 127b is provided on the vehicle rear side surface of the other end side of the coupling lock member 127, and the inclined surface 127b is inclined from below to above toward the vehicle rear side in a state where the front-wheel-side vehicle body 110 and the rear-wheel-side vehicle body 120 are coupled. When the rear wheel-side vehicle body 120 is tilted forward in the vehicle about the rotation axis 20a of the rear wheel 20 in a state where the 1 st cross member 113a of the front wheel-side frame 111 enters the pair of 1 st concave portions 121a, the 2 nd cross member 113b is configured to abut against the inclined surface 127b from below (see fig. 10).

When the 2 nd cross member 113b abuts on the inclined surface 127b from below, the connection locking member 127 tilts toward the vehicle front against the biasing force of the biasing member 127d, and the 2 nd cross member 113b enters the 2 nd recessed portion 121 b. When the 2 nd cross member 113b enters the 2 nd recessed portion 121b, the coupling lock member 127 tilts toward the vehicle rear side by the biasing member 127d, and the coupling between the front wheel-side vehicle body 110 and the rear wheel-side vehicle body 120 is maintained by the coupling lock member 127.

Each tilting member 126a is provided with a beam engaging portion 126e that engages with the cross beam 124a from above, behind, or below the vehicle. Further, a lock member engaging portion 126f is provided on the other end side of the beam engaging portion 126e of each tilt member 126a, and the lock member engaging portion 126f engages with an engaging pin 128a provided at one end of the tilt lock member (1 st regulating member) 128 from above or behind the vehicle.

The center side of each tilt lock member 128 is supported by the rear wheel side frame 121 and is tiltable around a tilt axis line 128b extending in the vehicle width direction, and an engagement pin 128a is provided at one end (lower end) of each tilt lock member 128. When one end portion of the tilt lock member 128 is tilted toward the vehicle front, the engagement between the engagement pin 128a and the lock member engagement portion 126f of the anti-toppling member 126 is released, and the other end portion of the anti-toppling member 126 is allowed to tilt upward.

When the anti-toppling member 126 is tilted upward, the lock member engagement portion 126f of the anti-toppling member 126 engages with the cross member (2 nd restriction member) 124a from above or the vehicle rear, thereby restricting the upward tilting of the anti-toppling member 126.

That is, the tilt of the anti-toppling member 126 is restricted to the position above the 1 st tilt position by engaging the lock member engaging portion 126f of the anti-toppling member 126 with the engaging pin 128a of the tilt lock member 128. When the locking member engaging portion 126f of the anti-toppling member 126 is engaged with the cross member 124a, the anti-toppling member 126 is restricted from tilting to a position above the 2 nd tilting position. Further, the beam engagement portion 126e of the anti-toppling member 126 is engaged with the cross beam 124a, thereby restricting the anti-toppling member 126 from tilting to a position below the 3 rd tilting position. A part of the anti-toppling member 126 may be engaged with another part of the rear wheel-side vehicle body 120, thereby restricting the anti-toppling member 126 from tilting to a position below the 3 rd tilting position. The 2 nd tilt position is a position above the 1 st tilt position, and the 3 rd tilt position is a position equivalent to the 1 st tilt position or a position slightly below the 1 st tilt position.

One end of a plate-shaped link member 129 is connected to the other end of the tilt lock member 128, and the other end of the link member 129 is connected to a position apart from the tilt axis 127c in the connection lock member 127. By the connection of the link member 129, in a state where the connection lock member 127 is disposed at the lock position a, the engagement pin 128a is engaged with the lock member engagement portion 126f or the engagement pin 128a is disposed at a position engageable with the lock member engagement portion 126 f. On the other hand, in the state where the coupling lock member 127 is disposed at the retracted position B, the engagement pin 128a and the lock member engagement portion 126f are not engaged with each other.

One end of an operating lever 130 as an operating member is connected to the other end side of the tilt lock member 128, and the operating lever 130 tilts about the tilt axis line 128b of the tilt lock member 128. As shown in fig. 1, 6, etc., since the other end of the operating lever 130 protrudes from the rear wheel side cover 120a of the rear wheel side vehicle body 120, the engagement between the engagement pin 128a and the lock member engagement portion 126f can be released and the coupling lock member 127 can be disposed at the retracted position B by tilting the operating lever 130 rearward or downward of the vehicle.

in the electric vehicle configured as described above, an example of a method of releasing the connection between the front wheel side vehicle body 110 and the rear wheel side vehicle body 120 will be described.

First, in a state where the seat unit 40 is detached from the rear wheel-side vehicle body 120, the grip portion 125c protruding from the upper end side of the back surface 33b of the seat support portion 33 is gripped with one hand, and the operating lever 130 is tilted rearward or downward of the vehicle while applying a force upward or rearward of the vehicle to the grip portion 125 c. This causes the following states: the engagement between the engagement pin 128a and the lock member engagement portion 126f is released, the connection lock member 127 is disposed at the retreat position B, and the 2 nd beam 113B is released from the 2 nd recess 121B.

When the rear wheel-side vehicle body 120 is tilted backward around the axle of the rear wheel 20 in this state, the auxiliary wheel 126b, which is the other end portion of the anti-toppling member 126, is grounded. When the rear wheel-side vehicle body 120 is further tilted backward around the axle of the rear wheel 20, the locking member engaging portion 126f of the anti-toppling member 126 engages with the cross member 124a at the 2 nd tilting position, and the upward tilting of the anti-toppling member 126 is restricted.

At this time, it is preferable that the position of the center of gravity of the rear-wheel-side vehicle body 120 is disposed between or near the ground contact position of the rear wheel 20 and the ground contact position of the auxiliary wheel 126b of the anti-toppling member 126 in the vehicle front-rear direction. This allows the rear wheel-side vehicle body 120 to be stably supported by the rear wheels 20 and the rollover prevention member 126.

On the other hand, when the rear wheel-side vehicle body 120 is tilted rearward, as shown in fig. 7, the 1 st recessed portions 121a are opened obliquely upward, and therefore the 1 st cross member 113a of the front wheel-side vehicle body 110 is stably supported by the 1 st recessed portions 121 a. That is, as shown in fig. 7, the 1 st cross member 113a of the front wheel side vehicle body 110 is less likely to fall out of the 1 st recessed portion 121a by having the front side contact portion FC. Therefore, the handle is separated from the handle portion 125c, the rear end side of the front wheel-side vehicle body 110 is lifted, and the 1 st cross member 113a is pulled out from the 1 st concave portion 121a, whereby the front wheel-side vehicle body 110 can be detached from the rear wheel-side vehicle body 120. At this time, the rear wheel-side vehicle body 120 is also stably supported by the rear wheel 20 and the anti-toppling member 126. After thus disassembled, the front-wheel-side vehicle body 110 and the rear-wheel-side vehicle body 120 are placed on an automobile or the like.

Next, an example of a method of coupling the front wheel side vehicle body 110 and the rear wheel side vehicle body 120 will be described.

First, in a state where the anti-toppling member 126 is disposed at the 2 nd tilting position, the auxiliary wheels 126b of the anti-toppling member 126 and the rear wheel 20 are grounded. In this state, the 1 st cross member 113a of the front wheel-side vehicle body 110 is put into the 1 st recessed portion 121 a. This causes the front wheel-side vehicle body 110 to be supported by the 1 st recessed portion 121a and the front wheel 10.

Next, the rear-wheel-side vehicle body 120 is tilted forward around the axle of the rear wheel 20. Thereby, as shown in fig. 10, the 2 nd cross member 113b abuts on the inclined surface 127b of the coupling lock member 127 from below. When the rear wheel-side vehicle body 120 is further tilted forward around the axle of the rear wheel 20 in this state, the coupling lock member 127 tilts forward of the vehicle, and the 2 nd cross member 113b enters the 2 nd recessed portion 121 b. When the 2 nd cross member 113b enters the 2 nd recessed portion 121b, the coupling lock member 127 tilts toward the vehicle rear side by the biasing member 127d, and the coupling between the front wheel side vehicle body 110 and the rear wheel side vehicle body 120 is maintained by the coupling lock member 127.

in this way, according to the present embodiment, when the rear wheel-side vehicle body 120 is detached from the front wheel-side vehicle body 110 and the rear wheel-side vehicle body 120 is in the self-standing state, the 1 st cross member 113a (the 2 nd engaging portion) provided on the rear end side of the front wheel-side vehicle body 110 is supported by the 1 st recessed portion 121a (the 1 st engaging portion) of the rear wheel-side vehicle body 120, and the front wheel-side vehicle body 110 is supported by the front wheel 10 and the 1 st recessed portion 121a of the rear wheel-side vehicle body 120. Therefore, the person who performs the dismantling operation in this state does not have to support the front wheel side vehicle body 110. When the assembly work of the rear wheel side vehicle body 120 to the front wheel side vehicle body 110 is performed, the front wheel side vehicle body 110 can be supported by the 1 st recessed portion 121a of the rear wheel side vehicle body 120 and the front wheel 10 in a self-standing state in the same manner.

the 1 st recessed portion 121a of the rear wheel-side vehicle body 120 in the self-standing state includes: a lower contact portion LC that can contact from below the 1 st cross member 113a of the front wheel side vehicle body 110; and a front contact portion FC disposed at a position on the vehicle front side of the lower contact portion LC and at a position higher than the lower contact portion LC. Therefore, when the 1 st cross member 113a of the front wheel-side vehicle body 110 is engaged with the 1 st recessed portion 121a of the rear wheel-side vehicle body 120 in a self-standing state, the movement of the 1 st cross member 113a toward the vehicle front side is restricted or suppressed by the front contact portion FC of the 1 st engaging portion 121 a.

In a state where the front wheel-side vehicle body 110 and the rear wheel-side vehicle body 120 are coupled, the handle portion 125c is held by one hand, the operating lever 130 is operated by the other hand to release the coupling, and when the handle portion 125c is lifted in a state where the coupling is released, the rear wheel-side vehicle body 120 tilts back to become a self-standing state. In the self-standing state, the front wheel-side vehicle body 110 is supported by the 1 st recessed portion 121a of the front wheel 10 and the rear wheel-side vehicle body 120. Therefore, the disassembling operation can be easily performed.

After the connection between the front wheel-side vehicle body 110 and the rear wheel-side vehicle body 120 is released, the 1 st cross member 113a is continuously supported from below by the 1 st recessed portion 121a until the rear wheel-side vehicle body 120 tilts rearward of the vehicle and becomes self-standing. Therefore, after the front-wheel-side vehicle body 110 and the rear-wheel-side vehicle body 120 are disconnected from each other, the person who performs the dismantling operation can be in a state in which the rear end side of the front-wheel-side vehicle body 110 is supported by the self-supporting rear-wheel-side vehicle body 120 by only supporting the rear-wheel-side vehicle body 120 to make the rear-wheel-side vehicle body 120 in a self-supporting state. This structure is advantageous in facilitating the disassembling operation.

In the present embodiment, when the tilt restriction by the tilt lock member 128 is released by the operation lever 130, the anti-toppling member 126 tilts to the 2 nd tilting position above the 1 st tilting position, and is restricted from tilting upward by the cross member 124a at this position.

Therefore, when the auxiliary wheels 126b of the anti-toppling member 126 are grounded, the center of gravity position of the rear wheel-side vehicle body 120 is shifted rearward of the vehicle, and for example, the center of gravity position is disposed between the ground contact portions of the rear wheels 20 and the ground contact portions of the auxiliary wheels 126b, so that the rear wheel-side vehicle body 120 can be stably supported by the rear wheels 20 and the anti-toppling member 126.

in the present embodiment, when the coupling lock member 127 is moved to the retracted position B by the operating lever 130 and the locking of the coupling between the front wheel-side vehicle body 110 and the rear wheel-side vehicle body 120 is released, the tilt restriction by the tilt lock member 128 is released, and the tip-over prevention member 126 tilts to the 2 nd tilt position above the 1 st tilt position and is restricted from tilting upward by the cross member 124a at that position. Therefore, when the releasing operation of the coupling is to be performed, the rear wheel-side vehicle body 120 is in a state of being stably supported by the rear wheel 20 and the rollover prevention member 126, which is advantageous in that the releasing operation of the coupling is facilitated.

When the tilt lock member 128 is tilted, the coupling lock member 127 is also tilted by the link member 129. Therefore, when the releasing operation of the coupling is performed, the tilt restriction by the tilt lock member 128 is released in conjunction therewith, and the rear wheel side vehicle body 120 can be stably supported by the rear wheels 20 and the anti-toppling member 126 easily and reliably. Further, the operation lever 130 may be fixed to the coupling lock member 127, and when the coupling lock member 127 is tilted, the tilt lock member 128 may be tilted by the link member 129.

Further, since the anti-overturn device 126, which is disposed at the 1 st inclination position when the front wheel-side vehicle body 110 and the rear wheel-side vehicle body 120 are connected to each other to prevent the electric motorcycle from overturning rearward, can be used to support the rear wheel-side vehicle body 120 from which the connection with the front wheel-side vehicle body 110 has been released, it is not necessary to provide a dedicated device for supporting the rear wheel-side vehicle body 120.

Further, by checking the tilting state of the tiltable lever 130 provided to the rear wheel-side vehicle body 120, the tilt restriction state by the tilt lock member 128 and the lock state by the coupling lock member 127 can be physically checked. Therefore, it is possible to prevent an unreasonable operation such as tilting the rear wheel side vehicle body 120 backward in a state where the tilt restriction by the tilt lock member 128 and the lock by the coupling lock member 127 are not released. When the front wheel side vehicle body 110 and the rear wheel side vehicle body 120 are coupled, the tilt restriction state by the tilt lock member 128 and the lock state by the coupling lock member 127 can be physically confirmed.

In addition, in a state where the upward tilting is restricted by the tilt locking member 128, the downward tilting of the falling prevention member 126 is restricted by the cross member 124a of the rear wheel side frame 121. When the tilt restriction by the tilt lock member 128 is released and the anti-toppling member 126 tilts to the 2 nd tilting position, the upward tilting of the anti-toppling member 126 is also restricted by the same cross member 124 a. Therefore, the structure for controlling the tilting of the anti-toppling member 126 can be made simple, which is advantageous in an electric vehicle that has a strong demand for weight reduction and a limited design space.

In the present embodiment, the case where the tilt lock member 128 and the coupling lock member 127 are tilted by the operating lever 130 is shown, but it is also possible to configure, for example, such that the output shaft of the speed reducer is coupled to at least one of the tilt lock member 128 and the coupling lock member 127, and the drive shaft of the speed reducer is driven by a motor. In this case, the controller 80 may be configured to control the motor 50 in response to the received lock release signal or lock signal.

In the present embodiment, the seat unit 40 is disassembled into the front-wheel-side vehicle body 110 and the rear-wheel-side vehicle body 120 after being detached from the vehicle main body 30. In contrast, the front-wheel-side vehicle body 110 and the rear-wheel-side vehicle body 120 can be disassembled without detaching the seat unit 40. In the case where the seat unit 40 is not attached to the rear wheel-side vehicle body 120 but to the front wheel-side vehicle body 110, or in the case where the seat unit 40 is small, there is a case where it is not necessary to detach the seat unit 40.

In the present embodiment, the anti-toppling member 126 is shown as protruding rearward of the vehicle with respect to the rear wheel 20, and the anti-toppling member 126 is tilted upward to support the rear wheel-side vehicle body 120 with the auxiliary wheel 126b at the other end portion of the anti-toppling member 126 and the rear wheel 20. In contrast, the anti-toppling member 126 may be a member without the auxiliary wheel 126 b. In this case, the electric vehicle can be prevented from falling backward by the fall prevention member 126, and the rear-wheel-side vehicle body 120 can be supported by the other end portion of the fall prevention member 126 and the rear wheel 20.

In the present embodiment, when the center of gravity of the rear wheel-side vehicle body 120 is located rearward of the vehicle with respect to the rotation axis 20a of the rear wheel 20, the anti-toppling member 126 may be configured not to be tilted upward from the 1 st tilting position, but to be provided with a protruding member protruding forward of the vehicle with respect to the rear wheel-side vehicle body 120.

In this case, one end of the protruding member is supported by the rear wheel-side vehicle body 120 and can tilt in the vertical direction. In the coupled state of the front wheel side vehicle body 110 and the rear wheel side vehicle body 120, the projecting member is disposed at the 1 st tilting position so as to extend in the vehicle front-rear direction, for example. When the connection between the front wheel-side vehicle body 110 and the rear wheel-side vehicle body 120 is released, the projecting member can tilt to the 2 nd tilt position above the 1 st tilt position after the release of the connection. Thus, when the rear wheel-side vehicle body 120 is supported by the other end portion of the protruding member and the rear wheel 20, the center of gravity of the rear wheel-side vehicle body 120 is shifted toward the front of the vehicle than when coupled.

instead of the 1 st recessed portion 121a, a cross member, an engagement pin, or the like extending in the vehicle width direction may be provided on the rear wheel side frame 121, and instead of the 1 st cross member 113a, a substantially U-shaped recessed portion opening obliquely downward toward the vehicle front direction, for example, may be provided on each of the side members 112 of the front wheel side frame 111, and the cross member, the engagement pin, or the like of the rear wheel side frame 121 may be engaged with each recessed portion.

Instead of the 2 nd recessed portion 121b, a cross member, an engagement pin, or the like extending in the vehicle width direction may be provided on the rear wheel side frame 121, a substantially U-shaped recessed portion opening upward, for example, may be provided on each side rail 112 of the front wheel side frame 111 instead of the 2 nd cross member 113b, and the cross member, the engagement pin, or the like of the rear wheel side frame 121 may be engaged with each recessed portion. The front wheel-side vehicle body 110 and the rear wheel-side vehicle body 120 may be detachably coupled to each other by another method.

in the present embodiment, the case where the 1 st recessed portion 121a and the 2 nd recessed portion 121b each having a substantially U-shape are provided in the rear wheel side frame 121 is shown. On the other hand, if the 1 st recessed portion 121a is a member that is open to the vehicle front side while coming into contact with the 1 st cross member 113a from below, above, and the vehicle rear side when the front wheel side vehicle body 110 and the rear wheel side vehicle body 120 are coupled, the same operational effects as described above can be obtained even if the 1 st recessed portion 121a has another shape. Further, as long as the 2 nd concave portion 121b is also a member that is in contact with the 2 nd cross member 113b from above, behind, and in front of the vehicle and is open downward when the front wheel side vehicle body 110 and the rear wheel side vehicle body 120 are coupled, the same operational effects as described above can be obtained even if the 2 nd concave portion 121b is of another shape.

In addition, even when the recessed portion that opens obliquely downward toward the vehicle front direction is provided in the front wheel side frame 111 instead of the first cross member 113a as described above, the same operational effects as described above can be achieved even if the recessed portion is of another shape, as long as the recessed portion is a member that opens obliquely downward toward the vehicle front direction, such as a cross member, an engagement pin, or the like that contacts the rear wheel side body 120 from above, below, and the vehicle rear direction when the front wheel side body 110 and the rear wheel side body 120 are coupled.

In the case where the recessed portion that opens upward is provided in the front wheel side frame 111 instead of the 2 nd cross member 113b as described above, the same operational effects as described above can be obtained even if the recessed portion has another shape, provided that the recessed portion is a member that opens upward and comes into contact with a cross member, an engagement pin, or the like of the rear wheel side vehicle body 120 from below, behind, and in front of the vehicle when the front wheel side vehicle body 110 and the rear wheel side vehicle body 120 are coupled.

In the present embodiment, the case where the tilt of the anti-toppling member 126 to the position above the 2 nd tilt position is restricted by engaging the lock member engaging portion 126f of the tilt member 126a with the cross member 124a is shown. In contrast, a portion between the other end of the tilting member 126a and the tilting center 126d may be engaged with the rear wheel side cover 120a and the rear wheel side frame 121, thereby restricting the tilting of the anti-toppling member 126 to a position above the 2 nd tilting position. As long as the rear wheel-side vehicle body 120 can be supported by the rear wheels 20 and the anti-toppling member 126, the anti-toppling member 126 may be restricted from tilting to a position above the 2 nd tilting position by another structure.

In addition, when the rear-wheel-side vehicle body 120 is tilted backward and the anti-toppling member 126 is grounded by releasing the connection between the rear-wheel-side vehicle body 120 and the front-wheel-side vehicle body 110 in the state where the seat unit 40 is attached, the center of gravity of the entire structure including the seat unit 40 and the rear-wheel-side vehicle body 120 may be disposed between the ground contact position of the rear wheel 20 and the ground contact position of the auxiliary wheel 126b of the anti-toppling member 126. In this case, the disassembling operation of the rear wheel-side vehicle body 120 and the front wheel-side vehicle body 110 can be easily performed in a state where the seat unit 40 is attached. On the other hand, this operation can be easily performed also in the case where the rear wheel side vehicle body 120 is attached to the front wheel side vehicle body 110 after the seat unit 40 is attached to the rear wheel side vehicle body 120.
