Can be installed.
[0046]
In addition, each of the component attachments 45L and 45R is formed in a shape to be in contact with a part of the outer periphery of the upper case 32, and an engaged portion 46a is provided at one end along the circumferential direction of the upper case 32. A holding member 46, an operation lever 47 that is rotatable around an axis parallel to the axis of the upper case 32, and has a base end connected to the other end of the first holding member 46; An intermediate lever 48 whose one end is connected to an intermediate portion of the operation lever 47 by enabling rotation about an axis parallel to the rotation axis of the operation lever 47, and rotation around an axis parallel to the rotation axis of the operation lever 47. As far as possible, one end is connected to the other end of the intermediate lever 48, and the other end is provided with an engaging portion 49a which is detachably engaged with the engaged portion 46a of the first holding member 46. 2 comprising a holding member 49, A lever holding member 52 that resiliently engages with the operation lever 47 while holding the case 32 to hold the rotation position of the operation lever 47, and a mounting boss 53 for mounting the wind screen 37 are provided. It is provided on one holding member 46.
[0047]
According to the component attachments 45L and 45R, the attachment and detachment to and from the upper case 32 can be easily performed by rotating the operation lever 47.
[0048]
The intermediate lever 48 includes a vertical rod portion 48a rotatably connected to one end of the second holding member 49, and a pair of horizontal rod portions 48b, one end of which is connected to both ends of the vertical rod portion 48a at right angles. 48b, and connecting portions 48c, 48c provided at the other ends of the two lateral rod portions 48b, 48b and rotatably connected to an intermediate portion of the operation lever 47, and are integrally formed in a substantially U-shape. When the operation lever 47 is turned to the side where the operation lever 47 is engaged with the lever holding member 52, at least a portion of the both lateral rod portions 48b, 48b on the operation lever 47 side. Are provided.
[0049]
Therefore, a part of the intermediate lever 48 is stored in the operation lever 47 in a state where the component attachments 45L and 45R are attached to the upper case 32, and the component attachments 45L and 45R in the attachment state to the upper case 32 are attached. It can be made compact.
[0050]
At one end of the second holding member 49, a connecting cylinder portion 49b surrounding the vertical rod portion 48a is provided so as to rotatably connect the vertical rod portion 48a of the intermediate lever 48. The second holding member 49, which has been disengaged from one end of the member 46 and rotated to a predetermined position about the axis of the vertical rod portion 48a, is slid by a predetermined amount along the vertical rod portion 48a. One of the two lateral rods 48b, 48b fits into the notch 64 provided at one end in the axial direction of the connecting cylinder 49b, so that the intermediate lever 48 and the second holding member 49 are removed from the upper case 32. The relative posture can be kept constant, and the mounting work is smoothly performed without any support due to the wobbling of the second holding member 49 when mounting the component mounting tools 45L and 45R to the upper case 32. This Can.
[0051]
Further, the portions of both lateral rod portions 48b, 48b of the intermediate lever 48 corresponding to the respective storage grooves 62, 62 are in frictional contact with the side surfaces of the respective storage grooves 62, 62. An opposing frictional force is generated between the two lateral rod portions 48b, 48b of the intermediate lever 48 and the operation lever 47, so that a good operation feeling can be obtained when the operation lever 47 is rotated.
[0052]
Moreover, since the lever holding member 52 resiliently engages with the operation lever 47 at a position shifted upward or downward from the center position of the operation lever 47 in the direction along the axis of the upper case 32, Even if the width of the operation lever 47 in the direction along the axis is not increased, it is possible to secure a sufficient space for a finger for rotating operation on the operation lever 47, and to make the component attachments 45L and 45R compact. It can contribute more.
[0053]
FIG. 13 shows a second embodiment of the present invention, in which a mini cowl 66 is disposed in front of the steering handle 22 as a front component, and a mounting plate 67 provided on the rear side of the mini cowl 66 is shown.

Further, in particular, at one end of the second holding member, there is provided a connecting cylinder portion surrounding the vertical rod portion for rotatably connecting the vertical rod portion of the intermediate lever. When the second holding member, which has been disengaged and is rotated to a predetermined position about the axis of the vertical rod, is slid along the vertical rod, one of the two horizontal rods is connected to the connecting cylinder. Is fitted in the notch provided at one end in the axial direction, so that the relative position of the intermediate lever and the second holding member can be kept constant when detached from the upper case. At the time of mounting, the mounting operation is not hindered by the wobbling of the second holding member, and the mounting operation can be performed smoothly.
[0058]
According to the second aspect of the present invention, it is possible to easily attach the front-placed component to the upper case while positioning the component.
[0059]
According to the third aspect of the present invention, the lever holding member fixed to the first holding member cooperates with the first holding member with the second holding member having the engaging portion engaged with the engaged portion. When the operating lever is rotated to a position where the operating lever is rotated to the position where the upper case is held, the operating lever can be elastically engaged with the operating lever to maintain the rotating position of the operating lever. .
