Embodiments of the present invention will be described below with reference to the drawings. First, as shown in FIG. 2 showing a side shape of the scooter type vehicle to which the embodiment is applied, FIG. 3 which is a plan view thereof, and FIG. The body frame is formed of a steel pipe framework, and includes a head pipe 1 located at a front end,
A down tube 2 extending downward from the lower end of the head pipe 1; a rear frame 3 extending rearward and upward from the vicinity of the lower end of the down tube 2 to form a substantially elliptical shape in plan view; A front cross member 4 for connecting the front part, the center part and the rear part in the left-right direction,
A mid cross member 5 and a rear cross member 6 are provided. A steering handle 8 is provided at an upper end of a front fork 7 slidably supported by the head pipe 1, and a front wheel 9 is pivotally supported at a lower end.

A power unit 10 is supported at the front end of the mid cross member 5 via a link mechanism such that the power unit 10 can swing up and down.
And the rear of the power unit 10 and the rear cross member 6 are connected via a rear cushion 12.

[0010] The outer periphery of the body frame is covered by a body cover made of a hard synthetic resin. The body cover is divided into a plurality of members, of which a rear upper cover 14, a rear lower cover 1
5 and an under cover 16 are provided.

The rear upper cover 14 is formed as a single unitary member formed of an annular member whose front and rear portions and both left and right sides are surrounded by wall surfaces and whose upper and lower surfaces are open. A luggage box 17 for accommodating a helmet or the like is fitted inside the rear upper cover 14, and an opening on the upper surface of the rear upper cover 14 is openably and closably covered by a seat 13 hinged at a front end thereof.

A rear fender 18 that covers an upper portion of the rear wheel 11 is mounted on a rear portion of the rear upper cover 14. The rear lower cover 15 and the under cover 16 have a structure divided into right and left.

Next, a vehicle body mounting structure of the main stand 20 will be described. The main stand 20 is pivotally supported at the rear end of a dish-shaped stand bracket 21 welded to the mid cross member 5 via a stand shaft 22 extending in the left-right direction so as to be able to swing back and forth. The main stand 20 includes a stand cover 23 supported by the stand shaft 22 and a stand body 24 substantially U-shaped in the vehicle width direction welded to a rear surface of the stand cover 23. The elastic force of the toggle spring 25 stretched between the bracket 21 and the bracket 21 urges the storage position shown in FIG. 2 and the upright position shown in FIG. 4 to stop stably.

As is apparent from FIG. 5 in which the main stand 20 is enlarged and FIG. 6 which is a cross-sectional view taken along line 6-6, the standing position of the main stand 20 is such that the front surface of the stand cover 23 is located on the rear wall of the stand bracket 21. It is regulated by contact.

The structure of the connection between the main stand 20 and the stand bracket 21 is evident in FIG. 5 and FIGS. In these figures, on the outer peripheral portion of the stand shaft 22, a retaining projection 26 which protrudes in the radial direction near a head 25 formed at one end and which is an example of a sampling prevention means in the present invention is integrally formed. I have. A diametrical through hole 27 is formed at the tip end of the stand shaft 22.

A section A in FIG. 1 shows an enlarged section of the projection 26. A pair of left and right mounting brackets 28 projecting rearward are formed on the left and right rear portions of the side wall of the stand bracket 21, and a mounting hole 29 through which the stand shaft 22 is inserted and one bracket 28 (the left bracket 28 in the embodiment). A cut-out portion 30 is formed in a part of the periphery of the mounting hole 29 formed to allow the projection 26 to pass therethrough.

The left and right side walls 31 of the stand cover 23 which overlap the inside of the left and right brackets 28 are also provided with mounting holes 2.
The same mounting hole 32 as 9 is formed, and a similar notch 33 is formed on the side of the left and right mounting holes 32 where the notch 30 is formed (the left side in this embodiment).

The notch 33 allows the projection 26 to pass therethrough, matches the mounting holes 29 with the mounting holes 32, and cuts the main stand 20 when the main stand 20 is laid in a state close to the retracted state. It is formed so as to coincide with the portion 30.

Therefore, as shown in FIG. 1, the stand covers 23 are put inside the left and right brackets 28 so that the brackets 28 and the mounting holes 32 are aligned with each other, and the main stand 20 is laid substantially horizontally, so that the notch 30 And the notch 33 are made to coincide with each other. Subsequently, the tip of the stand shaft 22 is inserted into the mounting hole 29 formed in the left bracket 28 in this embodiment,
Then, the protrusion 26 is aligned with the notch 30 and pushed as it is, and the protrusion 26 is inserted into the side wall 31.

At this time, since the tip of the stand shaft 22 projects outward from the mounting hole 29 of the right bracket 28,
When the split pin 34 is passed through the through hole 27 formed in the projection, the stand shaft 22 is prevented from dropping.

Further, when the main stand 20 is set up,
As shown in FIG. 5, the position of the notch 33 is shifted by about 90 ° from the notch 30 so that the protrusion 26 comes into contact with the inner surface of either the side wall 31 or the bracket 28, and does not come off.

In this case, the position of the projection 26 is a state in which the stand shaft 22 is simply inserted, that is, the projection 26 is rotated around the axis as shown in FIG. Or any of them.

As described above, when the main stand 20 is connected to the stand bracket 21 by the stand shaft 22, when the main stand 20 is set up and parked, the stand shaft 22
Can not be extracted. Therefore, the main stand 20 cannot be retracted by the stand lock to prevent the vehicle from being stolen by preventing the vehicle from running, and the main stand 20 itself cannot be separated from the vehicle body in the stand locked state. Theft can be more reliably prevented.

In this embodiment, since the split pin 34 is used, the stand shaft 22 is prevented from falling off even when the main stand 20 is in the retracted state. However, it is not always necessary to prevent the split pin 34 from coming off. Also, a protrusion similar to the protrusion 26 is formed at the tip of the stand shaft 22, and the mounting holes 29 and 32 of the right bracket 28 and the side wall 31 are notched. After the portions 30 and 33 are formed and the stand shaft 22 is passed through, the stand shaft 22 can be rotated around the axis to prevent the stand shaft 22 from coming off. Further, the stand shaft 22
Of forming a threaded portion at the tip, here but it may also be prevented from slipping out by fastening the nut.

Next, the stand lock device will be described with reference to FIGS. Reinforcing members 40 and 41 are welded to the rear inner surface of the stand bracket 21 and the back surface of the stand cover 23, respectively. When the main stand 20 is in the upright state, the reinforcing member 40, the stand bracket 21, the stand cover 23, and the reinforcing member 41 overlap in the front-rear direction. In this state, the slit 42 penetrating the reinforcing member 40 and the stand bracket 21, and the stand cover 23 and the slit 43 penetrating the reinforcing member 41 face each other.

A base plate 44 is fixed to the inside of the stand bracket 21 with bolts 45. A projection 46 (FIG. 5) formed at the rear end of the base plate 44 fits into a groove (not shown) formed in the reinforcing member 40. They are locked together.

As apparent from FIG. 6, the base plate 4
A cam plate 47 is pivotally supported by bolts 48 on the upper surface of 4, and a spring 51 is stretched between a spring hook 49 provided on the cam plate 47 and a spring hook 50 provided on the base plate 44. The cam plate 47 is urged in the clockwise direction in FIG. 6 by the elastic force of the spring 51. As shown by the imaginary line, the stop plate 52 provided on the cam plate 47 is mounted on the bracket 5 provided on the base plate 44.
3 stops at the unlock position where it abuts. When the cam plate 47 is at the unlocked position, it is detached from the stand cover 23 and the slit 43 of the reinforcing member 41, and the main stand 20 can be swung.

A Bowden wire 55 connecting an operation lever 54 and a cam plate 48, which will be described later, comprises an outer tube 56 and an inner cable 57. One end of the outer tube 53 is connected to the bracket 53 of the base plate 44.
, And one end of the inner cable 57 is attached to the spring hook 50 of the cam plate 47.

Accordingly, when the cam plate 47 is rotated counterclockwise in FIG. 6 against the elastic force of the spring 51 by pulling the inner cable 57, the cam plate 47 is moved to the stand cover 23 and the reinforcing member 41. And the main stand 20 is locked in the upright position.

The operation lever 54 is a member for rotating the cam plate 47 between a lock position and an unlock position.
As shown in FIG. 4, it is provided inside a luggage box 17 which is covered by a seat 13 which can be locked by a seat lock (not shown), thereby preventing the vehicle from being stolen.

The operation lever 54 is connected to the luggage box 21.
At the rear wall via a pin 58. At the rear end of the pin 58, an inner cable 57 of the Bowden wire 55 is connected.
The arm 59 to which is attached is fixed. Reference numeral 60 denotes a hook which engages with a lock fitting 61 provided on the bottom of the rear end of the seat 13 to lock the seat 13 in the closed position.

When the operation lever 54 is operated, the inner cable 57 is pulled, and the cam plate 47 rotates to the solid line position in FIG.
Is locked in the upright position. Conversely, when the operation lever 54 is operated to loosen the inner cable 57, the cam plate 47 is rotated to the imaginary line position in FIG. 6 by the elastic force of the spring 51, and the lock of the main stand 20 is released.

As shown in FIG. 4, when the seat 13 is locked in the closed position, the pin 62 provided at the front end pivot cannot be pulled out, and the seat 13 is locked.
, And operating the operation lever 54 is also prevented.
