Unlike the general scooter structure in which the parts around the front fork are covered with the front and rear covers, this motorcycle has a structure with a coverless type impression. The synergistic effect of this structure and the space under the seat described below gives the impression of a naked scooter. In particular, by placing a pipe-shaped headlight guard 16 from the side to the front side under the headlight, and further exposing the support frame under the seat to the side, the entire model can be used as a naked scooter. It has a more integrated impression. In addition, an inner upper cover 18 behind the front fork, left and right upper leg shields 17 extending to the left and right of the inner upper cover, an inner cover 19 continuous under the inner upper cover, and a leg shield 21 in front of the inner cover By providing the cover, a cover structure having a function of shielding the leg portion is provided like a general scooter. However, these parts around the front fork are not covered by the cover. A step floor 20 is provided under the inner cover, and a lower portion of the step floor is covered with a lower cover 22. A side stand 23 is provided on the left side of the lower cover. In the vehicle body frame behind the side stand, a unit swing mechanism that incorporates the engine on the front side and supports the rear wheel 36 on the rear side is supported by the rear suspension 28 so as to swing in the vertical direction. The structure including the step floor and the unit swing mechanism is a general scooter structure. For example, the unit swing mechanism is a belt converter provided on the left side of the main stand 24 under the unit and also serving as a swing arm that changes the driving force of the engine and transmits the resulting power to the rear wheels. A case 25, an inner rear fender 26 for covering the upper half of the rear wheel and preventing mud and water from entering the space under the seat, and an air cleaner 27 provided on the belt converter case and connected to the engine. A pair of left and right rear side covers 29, a rear light 30 behind the rear side cover, a left and right rear direction indicator 34 under the rear light, and a rear seat occupant can be gripped in the vicinity of the seat on the rear suspension 28. There is a rear grip 31 and a rear step 38.

  Further, as shown in FIGS. 2 to 4, the motorcycle according to the present embodiment has a space S under the seat provided under the seat 1, and this space has left and right openings K on the side of the vehicle body. Is visible. The space S under the seat is formed in the space under the seat 1 that can accommodate a load, is visible from the side through the opening K, and opens toward the front step floor 20. This structure can provide an appearance (so-called naked feeling) with less cover. Applicants of the present application have constructed this structure that generally changes the impression of a scooter where the parts under the seat were covered with a cover. Reference numeral 37 indicates a hook for holding a load accommodated in the space S under the seat. A total of four hooks, two at each of the front and rear corners of the space, are provided, making it possible to stably fix the luggage in the space under the seat using a net or the like while providing a naked feeling.

  The seat 1 is provided on a side portion of the motorcycle body (in the present embodiment, on the right side in the traveling direction), and is held by a hinge provided on the right pipe frame. The sheet can be opened towards the side. The seat, which can be seated by the driver when the seat is closed, includes a seat portion 1a and a bottom plate portion 1b (see FIGS. 5 to 7). By swinging the entire seat 1 toward the side with the hinge as a center, and opening the space S under the seat at the top, a large load can be accommodated. The seat 1 in the closed state can be locked to the vehicle body side by a seat catch b held by the left pipe frame 3. Even when the seat is closed, a small baggage or the like can be taken in and out through the opening on the left and right front sides.

  The seat support frame 2 includes left and right pipe frames 3 formed integrally with the seat 1 and a pair of left and right elastic members 6 provided on the pipe frame 3. When the seat 1 is closed, the elastic member 6 can come into contact with a frame or cover on the vehicle body side (contact portion 9a in the first side cover 9 in this embodiment). As shown in FIG. 9, the pipe frame 3 includes a pair of pipe members extending in the front-rear direction. The pair of pipe frames 3 are connected to each other by connecting members h1 and h2, and are integrally coupled to the bottom plate portion 1b of the seat 1. Two frame members D are positioned inside the contact portion 9a. The frame D extends upward from a cross pipe C connecting the pair of left and right seat frames B. Thus, the frame supports the weight of the seat on the contact portion 9a. With this structure, the weight of the seat is supported at four locations, that is, a pair of left and right contact portions 9a, a hinge a, and a seat catch b.

  Each elastic member 6 is fixed by being fitted to a bracket 3 a that is firmly welded to the front end of the corresponding pipe frame 3. The elastic member 6 is made of an elastic material such as rubber, a rubber material, or a resin material, and can be fitted. When the seat 1 is closed by swinging from the open state, the elastic member 6 contacts the contact portion 9 a of the first side cover 9. As described above, the elastic member 6 can limit the further swinging motion of the seat and can absorb the impact. Furthermore, the seat 1 in the closed state can be elastically supported, and thereby can effectively absorb vibration during traveling. As shown in FIGS. 5 and 12, the elastic member 6 according to the present embodiment has two mushroom-shaped protrusions 6a integrally formed on the upper surface. Each elastic member 6 is configured such that the projection 6a is inserted into two holes formed in the bracket 3a, fixed, and fitted.

  Further, as shown in FIG. 11, in the seat support frame 2 according to the present embodiment, the pair of left and right grip covers 7 are fitted on the welding bolts of the brackets firmly welded to the pipe frame 3 by the bolts 7 a and 7 b. The pair of left and right grip covers 7 have substantially the same width as each pipe frame 3. On the outer surface of the rear side of the vehicle body, the right and left sides of the left and right grip covers 7 cover the outsides of the hinge a and the seat catch respectively (see FIGS. 6 and 7). Bolts 7a and 7b arranged in the vertical direction at the center of the grip cover are at a position lower than the center of the pipe frame. Thus, although the pipe frame 3 is covered with the grip cover on the side, it can be easily seen from above, and a person near the motorcycle can obtain a naked feeling. However, as will be described later, the mask portion 4 b of the outer front seat garnish 4 is positioned inside the pipe frame 3. Therefore, the inner part of the pipe frame cannot be seen from the upper side. In this way, an attractive appearance can be obtained by having hinge and seat catch structures inside and below the pipe frame which is difficult to see. Furthermore, the left-side grip cover 7 can be gripped when the driver tries to swing the seat 1 around the hinge a. Therefore, the convenience of the left-side grip cover 7 is greatly increased as compared with a structure that is merely a cover. In this embodiment, as shown in FIGS. 1 and 2, the cover extends from the rear end of the opening K to the rear end of the pipe frame 3. Accordingly, the length of the exposed portion of the pipe frame 3 is substantially the same as the length of the upper portion of the opening K. Therefore, the opening and the pipe frame provide a harmonious appearance, and it is possible to further create a naked impression.

  A pair of left and right support frame side covers cover the outer surface of the seat support frame 2 (a part as described below in the present embodiment). In the present embodiment, as shown in FIG. 2, only the outer surface of the portion where the elastic member 6 is formed is covered. Therefore, the outer surface of the pipe frame 3 is exposed.
