For example, when a sudden brake operation is required to operate the brake device, it is required to pull the operating lever toward the operator with a plurality of fingers gripping the handlebar while the vehicle is running. Similarly, in the case of a clutch device, when the clutch is gradually engaged by loosening the grip of the operating lever, the operation of the operating lever feels heavy, making fine adjustment of the clutch difficult.

In other words, it can be said that the vehicle lever operation device described in Patent Document 1 has room for improvement in terms of operational convenience for people with weak grip strength, such as women and the elderly.

The present invention has been made in view of the above-mentioned circumstances, and its object is to increase the degree of freedom in arranging the cylinder in the vehicle in a device including a cylinder, to effectively utilize the clearance space of the vehicle, and to reduce the grip strength.

The first engaging elongated hole 32 is formed in a state in which the second stationary shaft C2 is engaged with the front end portion of the second engaging elongated hole 33 in the vehicle front-rear direction in the process of gripping. It is formed in an arc shape with the axis as the center of the circle. The second engagement long hole 33 is formed in a state where the first fixed shaft C1 is engaged with the vehicle front-rear direction front end portion of the first engagement long hole 32 in the course of gripping operation. It is formed in an arc shape with the axis as the center of the circle.

Therefore, in the process of gripping the operation lever 30, the rotation center of the rotation is switched between the two positions, that is, the first fixed shaft C1 and the second fixed shaft C2. can be realized.

Further, according to the vehicle lever operating device 20 of the present embodiment, the vehicle front-rear direction rear end portion of the first hydraulic cylinder 40 (an example of the first cylinder) is formed in a cylindrical shape. The link mechanism 60 is formed such that its inner diameter portion engages with the outer peripheral surface of the vehicle front-rear direction rear end portion of the first hydraulic cylinder 40 so as to be rotatable in the circumferential direction with respect to the first hydraulic cylinder 40 . It further has an annular base portion 61 and an arm portion 63 that is connected to the annular base portion 61 and that rotatably supports a rotation link 64 .

Therefore, it is possible to appropriately adjust the relative positions of the first hydraulic cylinder 40 (an example of the first cylinder) and the link mechanism 60 in the circumferential direction according to the gap space or the position of the vehicle. The degree of freedom of arrangement of the hydraulic cylinder 40 in the vehicle can be further increased.

Further, according to the vehicle lever operation device 20 of the present embodiment, the hydraulic hose H (an example of the driving force transmission tube) one end of which is connected to the first output portion 43 and the operation input portion of the clutch device 4 of the vehicle 4A and has a second output portion 53 arranged to be pressable with respect to the operation input portion 4A, and a second input portion 52 connected to the other end of the driving force transmission tube. and a hydraulic cylinder 50 (an example of a second cylinder).

Therefore, even a two-step operation including a half-clutch operation can be easily performed by a vehicle driver who has a weak grip. Further, even when the clutch is gradually engaged by loosening the grip force with which the operating lever 30 is gripped, the operation can be facilitated and fine adjustment can be performed more appropriately.

[・First modification of the first embodiment]
A first modification according to the present embodiment will be described with reference to FIG. 10 .
FIG. 10 is a schematic diagram for explaining a first modified example according to this embodiment.

As shown in FIG. 10 , in this modification, the vehicle lever operation device 20 configured as described above is applied to the operation of the brake device 5 .

That is, the two-wheeled vehicle 1 is configured with a brake device 5 attached to the front wheel 7 . The brake device 5 is a hydraulic disc brake in which a disc rotor rotating integrally with the front wheel 7 is combined with a caliper body having a piston. The brake device 5 includes an operation input section 5A (not shown).

A second hydraulic cylinder 50 is attached to the operation input portion 5A of the brake device 5 .

The second hydraulic cylinder 50 has a second output 53 and a second input 52 (see FIG. 3). The second output portion 53 of the second hydraulic cylinder 50 is arranged so as to be able to press the operation input portion 5A of the brake device 5 . A second input portion 52 of the second hydraulic cylinder 50 is connected to the other end of the hydraulic hose H of the vehicle lever operating device 20 .

Similarly, in this modification, when the operation lever 30 is rotated by gripping operation, the operation wire 36 is pulled and the rotation link 64 is rotated, whereby the first hydraulic cylinder 40 , the first input portion 42 is pressed and the driving force is output through the first output portion 43 . As the driving force is output, the driving force is transmitted to the second hydraulic cylinder 50 through the hydraulic hose H connecting the first hydraulic cylinder 40 and the second hydraulic cylinder 50 .

By this transmission, the second hydraulic cylinder 50 presses the operation input portions 4A, 5A of the brake device 5 with its second output portion 53, and as a result, the brake device 5 generates frictional force on the disc rotor. As a result, the rotational force of the front wheels 7 is converted into thermal energy to stop the front wheels 7.

According to this modification, one end of the hydraulic hose H (an example of a driving force transmission tube) connected to the first output portion 43 is attached to the operation input portions 4A and 5A of the brake device 5 of the vehicle, and A second hydraulic cylinder 50 ( an example of a second cylinder), and

Therefore, the braking operation can be performed by switching between gradually applying the brake and instantaneously applying the brake according to the degree of the gripping operation.
Other configurations, effects, and the like are the same as those of the above-described first embodiment.
