Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a step holder for a motorcycle that includes a side cover and a pillion step.

(Prior art) In a motorcycle having a rear seat for a passenger, the upper end of the step holder is fixed by welding or the like to the seat rail that supports the rear of the seat, and the pillion step is pivotally supported at the lower end so that it can be raised and lowered. .

Furthermore, among the above-mentioned motorcycles, in on-road type motorcycles, side covers that cover the mounting portions of the battery and seat rail stay are attached from both sides of the lower part of the seat to the rear of the vehicle body.

This side cover is attached by fitting to an appropriate number of bosses fixed to the vehicle body frame.
This installation improves the exterior appearance and reduces air resistance during driving.

(Problem to be solved by the invention) However, the portion of the above-mentioned side cover that covers the exterior of the step holder is placed on the seat of the seat near the step holder because the passenger's legs are located there and receives the load while driving. A boss portion was provided on the rail stay to impart stress, and the step holder was used only to support the pillion step.

Therefore, an object of the present invention is to provide a step holder that reduces the number of parts by holding the side cover in the step holder, reduces costs, and improves installation workability.

(Means for solving the problem) The present invention was made in view of the above-mentioned purpose.
In a motorcycle that is equipped with side covers on both sides of the lower part of the seat and a step holder that supports a pillion step at the rear of the body frame,
The step holder is formed into a substantially triangular shape on the side, and its two apexes are fixed to the rear part of the vehicle body frame, and a reinforcing rib connecting the two apexes is formed with an attachment part for supporting the side cover, and the remaining part is fixed to the rear part of the vehicle body frame. It is characterized by a pillion step attached to one vertex.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

The motorcycle 1 is a two-seater on-road type with a tandem seat 3 for a rider and a passenger arranged at the rear of a fuel tank 2, and the fuel tank 2 has a main frame with a head pipe 4 fixed to the front end. The front end of the tandem seat 3 is fixed to the main frame 5, and the tandem seat 3 is supported on the upper part of a seat rail 6 that is arranged toward the rear of the vehicle body.
The front wheel 9 is attached to the lower end of the front fork 8 which is steered by
However, a rear wheel 11 is suspended at the rear of the vehicle body by a rear fork 10 and a rear suspension (not shown).

The motorcycle 1 includes an atsupaka cowl 14 equipped with a windshield 13 that covers the bar handle 7, the instrument panel 12, etc., and an engine (continuously below the atsupa cowl 14 and mounted at the bottom of the fuel tank 2). A full cowl 16 consisting of an under cowl 15 that covers the sides and lower part of the tandem seat 3 (not shown) is attached, and side covers 1 are attached to both sides extending from the lower end of the tandem seat 3 to the rear end of the vehicle
7 is installed.

The seat rail 6 is supported at approximately the middle by a seat rail stay 18.
A pillion step 20 for a fellow passenger is attached to 8 via a step holder 19.

The pillion step 20 is the step holder 1
The step holder 19 is rotatably supported by a support shaft 21 between the flanges 19a and 19a of the step holder 19, and the step holder 19 has the flanges 19a and
At both ends of the V-shaped member 19b extending from a,
It has a triangular shape in which mounting parts 19c and 19c are provided respectively, and the mounting parts 19c and 19c are connected by a reinforcing rib 19d, and is mounted to the seat rail stay 18 by screwing a bolt 22 that is inserted through the mounting parts 19c and 19c. .

The step holder 19 is integrally formed of lightweight aluminum alloy that is easy to cast and forge. One of the plurality of locking projections 17a for attachment provided on the side cover 17 is fitted into the through hole 23a.

As described above, since the step holder of this embodiment has a fitting part that supports the side cover using reinforcing ribs, the number of boss parts fixed to the vehicle body frame by welding can be reduced. , it is possible to shorten the installation work time and reduce costs.

Moreover, since the seat rail stay is attached to the seat rail stay by screwing with bolts instead of welding as in the conventional case, the degree of freedom in the attachment position is improved, and manufacturing errors can be easily accommodated.

(Effects of the invention) As explained above, the present invention forms the step holder of the pillion step arranged at the rear of the vehicle body frame in a substantially triangular shape on the side, and fixes its two apexes to the rear of the vehicle body frame. Since a mounting part for supporting the side cover is provided on the reinforcing rib that connects the two apexes, the number of mounting boss parts of the side cover that are fixed to the vehicle body frame by welding can be reduced, improving work efficiency. , it is possible to shorten installation time and reduce costs, and in addition, the reinforcing rib that connects these two apexes is designed to absorb the effects of the rider's own load on the pillion step and the longitudinal load applied when starting and stopping. Since the mounting portions of the side covers are not subjected to such loads, there is no risk of a load that would cause deformation to the side cover itself, and there is also no risk of large loads being applied to the joints between the side covers and other parts such as the rear cowl. do not have. In addition, since the pillion step is attached to the remaining one vertex of the step holder, which is formed in a triangular shape on the side, other than the two apexes fixed to the rear of the vehicle body frame, the rider's own load on the pillion step, starting and stopping, can be reduced. The load in the longitudinal direction that is applied to the step holder is effectively distributed and absorbed by the step holder and the vehicle body frame, so that sufficient strength of the step holder portion can be maintained.
