In the embodiment of the present invention, the first guide rotating body 71 is rotatably coupled to the second tilting body 32 portion located above the footrest portion 50 portion to which the second connecting member 82 to be described later is coupled. .

The first guide rotating body 71 is configured such that a groove is provided on the outer circumferential surface like a normal pulley so that a second connecting member 82 to be described later can pass while being wound.

In an embodiment of the present invention, the guide guide part 60 is configured such that a portion of the connection member 80 to be described later is positioned on a vertical extension line p to be described later. That is, when the handle operation part 10 is rotated left and right, in order to be twisted at the part of the connection member 80 located on the vertical extension line p, a part of the connection member 80 is vertically extended by the guide guide part 60 (p) is located in the

And it is configured to be positioned above the first coupling part 62 and is configured to be positioned on the side of the first tilting body 31 when viewed from the front.

In the embodiment of the present invention, the connecting member 80 is configured to connect the footrest unit 50 to the fixed frame 21 located on both sides of the handle operation unit rotation center axis o.

The connecting member 80 is composed of a first connecting member 81 and a second connecting member 82 .

In the embodiment of the present invention, the first connecting member 81 is configured as a pair. One end of the first connecting member 81 is coupled to the fixed frame 21 located on both sides of the handle operation unit rotational central axis o, and the other end of the first connecting member 81 is a first coupling located in the vertical extension line p. They are respectively coupled to the portions 62. (Hereinafter, a portion of the fixed frame 21 to which the first connecting member 81 is coupled is referred to as a first portion 83, and a guide guide portion to which the first connecting member 81 is coupled. (60) part is called a second part (84))

When the first connecting member 81 is composed of a non-variable member, the handle manipulation unit 10 and the fixed body 20 cannot be rotated. Therefore, in order to be able to rotate the handle operation unit 10 and the fixed body 20, the first connecting member 81 may be composed of a variable member whose shape is changed without increasing the length when an external force is applied, the present invention It is suggested that the first connecting member 81 and the second connecting member 82 are composed of a dyneema rope in the embodiment of.

Since the Dyneima rope has a specific strength 15 times stronger than a wire and has flexibility, which is a fiber characteristic, when the handle operation part 10 is rotated left and right, the fixed body 20 is bent along the rotation direction, and the guide guide part 60 will catch

When the handle operation part 10 and the tilting body 30 are inclined laterally, the first connecting member 81 located on the inclined side is bent, and the first connecting member 81 located on the opposite side is maintained in a tensioned state. .

In the embodiment of the present invention, the second connecting member 82 has one end coupled to the end of the second coupling part 63 protruding upward and the other end coupled to the middle portion of the footrest 50 . And the intermediate portion is configured via the first guide rotating body (71).

Referring to FIG. 3 , when the handle operation unit 10 and the tilting body 30 are inclined laterally, the gap between the first part 83 and the second part 84 positioned on the inclined side becomes narrower, and the The gap between the first part 83 and the second part 84 is widened. And since the first connecting member 81 does not stretch, when the gap between the first part 83 and the second part 84 is widened, the first connecting member 81 located on the side with the gap widened guides the guide part 60 . It is pulled toward the fixed frame (21). Accordingly, the guide guide part 60 rotates toward the fixed frame 21 and the first connecting member 81 positioned on the inclined side is bent. When the guide guide 60 is rotated toward the fixed frame 21, the guide guide 60 pulls the second connecting member 82 toward the fixed frame 21 so that one end of the footrest 50 is rotated upward. do.

When the handle operation part 10 and the tilting body 30 are inclined even slightly to the left or right, one end of the footrest part 50 rotates upward to push up the lower body of the occupant. And the weight of the lower body of the occupant pressing the footrest unit 50 acts as a force that suppresses one end of the footrest unit 50 from being rotated upward. Accordingly, the weight of the lower body of the occupant pressing the footrest part 50 acts as a force for suppressing the lateral inclination (tilting) of the handle operation part 10 and the tilting body 30 .

When the handle operation part 10 and the tilting body 30 are inclined to the side, the footrest part 50 is inclined to the side and at the same time, one end is rotated upward. Therefore, assuming that the footrest part 50 is wide left and right, when the handle operation part 10 and the tilting body 30 are inclined to the side, the footrest part 50 has the footrest part 50 that moves upward and downwards. There is a boundary line (hereinafter referred to as a tilting boundary line (x)) of the part of the footrest part 50 to be moved.

As shown in FIG. 5 a, the tilting boundary line (x) exists on both left and right sides as the handle operation part 10 and the tilting body 30 are inclined to the left and right. The part of the footrest part 50 located between the two tilting boundary lines (x) is upward when the handle operation part 10 and the tilting body 30 are inclined to the side regardless of whether the tilting body 30 is inclined to the left or to the right. will move to Therefore, when the footrest part 50 located between the two tilting boundary lines (x) is pressed, the handle operation part 10 and the tilting body 30 act as a force to suppress the lateral inclination.

The tilting boundary line (x) moves laterally as the first part 83 is moved laterally from the handle operation part's central axis of rotation (o), and the footrest part 50 to which the second connecting member 82 is coupled is one end. As it goes to the other end, it moves laterally.

The tilting boundary line (x) position is configured to be located outside the footrest 52 when the handle operation unit 10 is slightly rotated to the left or right, and the tilting boundary line (x) position is a first connection coupled to the fixed frame 21 . The position of the member 81 and the position of the second connection member 82 coupled to the footrest 50 can be adjusted.

Referring to FIG. 5 b, when the handle control unit 10 is rotated, the position of the first part 83 is rotated along the rotation direction of the handle control unit 10, and as the position of the first part 83 is moved, the tilting boundary line (x) ) will be moved. As the width r at which the first part 83 is moved left and right when the handle control unit 10 is rotated increases, the width at which the tilting boundary line x moves when the handle control unit 10 is rotated also increases. The width r at which the first part 83 moves left and right when the handle control unit 10 is rotated is the greatest when the first part 83 is located on the central axis of rotation of the handle control unit o when viewed from the side. It is small and becomes larger as it moves forward or rearward from the central axis of rotation of the handle control unit (o). Therefore, in order to reduce the width at which the first part 83 moves left and right when the handle control unit 10 is rotated left and right, the first part 83 is positioned on the central axis of rotation of the handle control unit o when viewed from the side. is composed

Referring to FIG. 4 , when the second part 84 is configured to be positioned on the vertical extension line p, between the second part 84 and the first part 83 when the handle operation part 10 is rotated left and right. The interval (s) does not change. Therefore, when rotating the handle operation unit 10 left and right, it is twisted at the first connection member 81 portion located on the vertical extension line p, and the second connection member 82 does not pull the footrest unit 50 upward. The handle operation unit 10 can be rotated smoothly.

It is most preferable that the second part 84 is configured to be located on the vertical extension line p as shown in FIG. 4, but as shown in a and b in FIG. may be

That is, the second part 84 is configured to be located on the vertical extension line p when viewed from the side, and is configured to be positioned at a point slightly away from the vertical extension line p when viewed from the front, and the vertical extension line p to both second portions 84 may be configured to have the same length.

When the second part 84 is configured to be positioned at a point slightly away from the vertical extension line p on both sides, the first part ( 83) rotates the vertical extension line (p) as a central axis, and one end of the first connecting member 81 rotates around the second portion 84 as a central axis. Accordingly, as the handle operation part 10 is rotated left and right, the length from the second part 84 to one end of the first connection member 81 is slightly shorter than the length from the second part 84 to the first part 83 . And, since the first connecting member 81 does not stretch, as the handle operation part 10 is rotated left and right, the guide guide part 60 rotates downward to determine the length and length from the second part 84 to the first part 83. The length from the second portion 84 to one end of the first connecting member 81 is equal to each other. Therefore, as the handle operation part 10 is rotated left and right, one end of the footrest part 50 is moved upward little by little by pulling the connection member 80, but when the handle operation part 10 is rotated left and right, the resistance is small, so the second The portion 84 may be configured to be located at a point a little further away from both sides of the vertical extension line (p).

When the second portion 84 is configured to be located at a point far away from the vertical extension line p, the footrest 50 rotates upward a lot when the handle operation unit 10 is rotated left and right. Therefore, it is not preferable that the second portion 84 be positioned at a point far away from the vertical extension line p since the resistance is large when the handle operation unit 10 is rotated left and right.

When the second part 84 is configured to be positioned in front or behind the vertical extension line p when viewed from above as in c and d in FIG. 6 , when the handle manipulation unit 10 is rotated to the left or right, the second part 84 ) to the first portion 83 on both sides of the length is different from each other. Therefore, when the handle control unit 10 is rotated to the left or right, the tilting body 30 and the handle control unit 10 are inclined to the side, so that the second part 84 is located in front or behind the vertical extension line p. It is not desirable to be

Most of the occupant's weight is carried on the saddle 42 and a little on the footrest 52, but the direction of the force pressing by the occupant's weight on the saddle 42 and the direction of the force trying to incline the tilting body 30 are close to 90 degrees. Even if only the weight of the lower body is loaded on the footrest 52, the inclination of the handle operation part 10 and the tilting body 30 is suppressed.

As described above, by connecting the footrest part 50 and the fixed frame 21 with the connecting member 80, when the passenger sits on the saddle 42 and puts his or her foot on the footrest 52, the handle operation unit 10 ) and the tilting of the tilting body 30 are suppressed, so that it is possible to easily hold the center of gravity.

In addition, although the fixed frame 21 is connected to the footrest part 50, a part of the first connecting member 81 is configured to be positioned on the vertical extension line p, thereby rotating the handle operation part 10 and the fixed body 20 to steer There are effects that can be done.
