DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motorcycle, and more particularly to an improvement in mounting and removing workability of a driver's seat and a carrier.

[0002]

2. Description of the Related Art There is a case where a driver's seat is attached to the upper part of a motorcycle body, and a carrier for loading luggage is mounted behind the seat. Conventionally, the following structure has been adopted as a structure for attaching the seat and the carrier to a vehicle body. First, for example, a locking piece formed at the front of the seat is locked to a locked piece formed near the rear of the fuel tank of the vehicle body,
Both sides of the rear portion of the seat are fastened to the vehicle body with bolts, thereby attaching the seat to the vehicle body. A carrier is arranged behind the seat, and legs formed at four corners of the carrier are fastened to the vehicle body with bolts, thereby attaching the carrier to the vehicle body.

[0003]

In the above-mentioned conventional motorcycle, since the seat and the carrier are separately mounted, naturally, the mounting bolts for the seat are used as mounting bolts.
Separate carriers are required. Therefore, a separate installation man-hour is required, and workability is poor. In order to perform maintenance on both the lower part of the seat and the carrier of the motorcycle, both the seat and the carrier must be removed. Also, when the maintenance of the lower part of the seat is performed, when only the seat is removed, the carrier is in the way and it is difficult to perform the work. Therefore, in this case, it is necessary to remove both the seat and the carrier. In such a case, the sheet and the carrier are naturally removed separately, which increases the number of work steps as in the case of the mounting work, and accordingly, the workability during maintenance is poor.
The present invention has been made in view of the above-described conventional circumstances, and has as its object to provide a motorcycle that can improve workability when a driver's seat and a carrier are attached to and removed from a motorcycle body. .

[0004]

SUMMARY OF THE INVENTION The present invention relates to a motorcycle in which a driver's seat and a carrier located behind the seat are arranged on an upper portion of a vehicle body frame. The bracket is fixed, and the connecting piece fixed to the front edge of the bracket and the connecting bracket fixed to the bottom plate of the seat are tightened with bolts to form a seat unit, and the locking piece is fixed to the bottom plate of the seat. A front leg is formed so as to be engageable with the locked piece of the vehicle body frame, and has a mounting groove at the front of the bracket of the carrier and near the connection bolt, the mounting groove being capable of being engaged with a support shaft of the vehicle body frame. At the same time, a rear leg having a mounting hole for a vehicle body frame is formed at a rear portion, and the seat unit locks the locking piece to the locked piece from the rear to the front of the vehicle at the same time. The mounting groove of the front leg is locked to the support shaft from the rear of the vehicle to the front, and the rear leg of the carrier is pivoted downward around the bolt to fix the rear leg to the rear end of the vehicle body frame by bolting. Therefore, it is characterized by being attached to the body frame.

[0005]

In the motorcycle according to the present invention, in order to attach the seat and the carrier to the vehicle body, a seat unit is formed by connecting the seat and the carrier with bolts in advance. In order to assemble the seat unit, first, the locking piece formed on the bottom plate of the seat is locked with the locked piece formed on the vehicle body, and at the same time, the mounting groove of the front leg of the carrier is connected to the support shaft of the vehicle body. And the rear leg is fastened with a nut while rotating the carrier downward around the connection bolt. As a result, the seat and the carrier are simultaneously attached to the vehicle body. Also, to remove the seat and the carrier from the motorcycle, first remove the bolts on the rear legs of the carrier, then remove the mounting groove from the support shaft and at the same time release the locking piece of the seat with the locked piece of the vehicle body. Remove from As a result, the seat and the carrier are simultaneously removed from the vehicle body. As described above, in the present invention, the seat and the carrier are connected in advance to form a seat unit, which is attached to or detached from the vehicle body.
The workability of attaching and detaching the seat and the carrier can be improved. Further, since the carrier is pivoted downward about the connecting bolt and the legs are then fastened with bolts, the strength of attaching the carrier to the vehicle body can be improved. Since the connecting bolt and the mounting groove of the front leg are close to each other, the front leg moves slightly when the carrier is rotated downward, so that no trouble occurs.

To conclude. Thereby, the sheet 10 and the carrier 11
Are simultaneously fixed to the body frame 2 as the seat unit 9.

To remove the seat unit 9 fixed to the motorcycle 1 from the body frame 2,
The bolts 16 and 16 that fasten the rear legs 15f and 15f of the carrier 11 are removed, and the cap nut 23 that fastens the front leg 15b is loosened. Then, the entire seat unit 9 is moved rearward to remove the front leg 15b. The locking piece 17c of the seat 10 is removed from the locked piece 2f while being removed from the bolt portion 20a. As a result, the seat 10 and the carrier 11 are simultaneously removed from the body frame 2 in a unitized state.

As described above, in the present embodiment, the sheets 10,
Since the carrier 11 is unitized into a seat unit 9 and the seat unit 9 is attached to the vehicle body frame 2, the locking pieces 17c for the seat 10 are provided.
Only need to be locked to the locked pieces 2f of the body frame 2, and there is no need to tighten with bolts. Therefore, the number of work steps for mounting and removing can be reduced as compared with a conventional apparatus in which a sheet and a carrier are separately mounted, and maintenance of the lower portion of the sheet 10 and the carrier 11 can be easily performed.

[0013]

As described above, according to the motorcycle of the present invention, the driver's seat and the carrier are connected to form a seat unit, and the locking pieces of the seat bottom plate are used as the locking pieces of the vehicle body. The mounting grooves in the legs of the carrier are locked to the support shaft from the rear to the front of the vehicle, and the carrier is bolted and fixed to the vehicle body while rotating around the connecting bolt, so that the mounting strength of the carrier can be improved. In addition, the number of steps for attaching and detaching the seat unit can be reduced, and the mounting workability can be improved, so that the maintenance of the lower portion of the seat and the carrier can be easily performed.
