By the way, various vehicle parts are mounted on the cowl stay due to the function of the vehicle. Therefore, it is desired to increase the holding force of the vehicle component.

An object of an aspect of the present invention is to provide a cowl stay structure for a saddle-ride type vehicle that can increase the holding force of vehicle components.

A cowl stay structure for a saddle-ride type vehicle according to one aspect of the present invention includes a head pipe (21) arranged in a front portion of a vehicle body, and a cowl (40) supported by the head pipe (21) and covering the front portion of the vehicle body. a cowl stay (49) for supporting, the cowl stay (49) extending forward and upward from the head pipe (21), a front stay (50) for supporting vehicle parts (80, 90), and the head pipe. and middle stays (60L, 60R) arranged rearwardly of (21) and connected to the front stay (50) , wherein the middle stays (60L, 60R) are provided as a pair of left and right middle stays (60L, 60R). The stays (60L, 60R) extend outward in the vehicle width direction and are then connected to the front stay (50) .
According to this configuration, the front stay is supported not only by the head pipe but also by the middle stay. Therefore, the vehicle component supported by the front stay can also be supported by the middle stay. Therefore, it is possible to increase the holding force of the vehicle component. In addition, since the head pipe is surrounded by the left and right middle stays and the front stay, it is possible to more effectively increase the holding force of the vehicle parts.

In one aspect of the present invention, the front stay (50) has a meter support portion (51) extending forward and upward from the head pipe (21) and supporting a meter (80). (54L, 54R) may extend rearward below the meter support (51).
This configuration does not require a large space around the meter, so that the degree of freedom in layout around the meter can be improved.

In one aspect of the present invention, the middle stay ( 60L, 60R) may be connected to the key cylinder bracket (70).
With this configuration, the key cylinder bracket also serves as the bracket for the middle stay, so the number of parts can be reduced.

In one aspect of the present invention, the front stay (50) has a meter support portion (51) that supports a meter (80), and the front stay (50) and the middle stays (60L, 60R) are connected to each other. The portion (JM) is arranged behind and above a connection portion (JH) between the head pipe (21) and the front stay (50), and the meter support portion (51) is arranged between the front stay (50) and the It may be arranged above the joint (JM) with the middle stays (60L, 60R) and in front of the joint (JH) between the head pipe (21) and the front stay (50). .
According to this configuration, compared with the case where the meter support portion is arranged below the connection portion between the front stay and the middle stay, it is possible to suppress the moment around the meter support portion from becoming excessive locally. can be done. In other words, when the meter, which is a heavy object, is supported by the front stay, the moment to each connecting portion can be distributed in a well-balanced manner. Therefore, the holding force of the meter can be increased more effectively.

In one aspect of the present invention, the front stay (50) includes a pair of upper and lower horizontal parts (56, 57) that respectively support upper and lower parts of the headlight (90), and the front stay (50) and the The connecting portion (JM) to the middle stays (60L, 60R) may be arranged between the pair of upper and lower horizontal portions (56, 57) in the vertical direction .
According to this configuration, when the upper and lower parts of the headlight, which is a heavy object, are supported by the pair of upper and lower horizontal parts, respectively, the distance between the connection part between the front stay and the middle stay and the center of gravity of the headlight can be adjusted. can be reduced exponentially. Therefore, the holding force of the headlight can be enhanced more effectively.

According to aspects of the present invention, it is possible to increase the holding force of vehicle components.

Although an example of connecting to is explained, the present invention is not limited to this. For example, the middle stays 60L, 60R may be connected to a different part from the key cylinder bracket 70. For example, the middle stays 60L, 60R may be connected to a bracket different from the key cylinder bracket 70.

In the above embodiment, the front stay 50 has the meter support portion 51 that supports the meter 80, the F/M connection portion JM is arranged behind and above the H/F connection portion JH, and the meter support portion 51 includes: Although an example in which it is arranged above the F/M connection JM and in front of the H/F connection JH has been described, the present invention is not limited to this. For example, the meter support section 51 may be arranged below the F/M connection section JM. For example, the arrangement position of each connecting portion of the front stay 50 can be changed according to the required specifications.

In the above-described embodiment, the front stay 50 includes a pair of upper and lower horizontal members 56 and 57 that support the upper and lower portions of the headlight 90, respectively. Although the example arranged between is given and demonstrated, it is not restricted to this. For example, the F/M connection JM may be arranged above the upper horizontal bridge 56 . For example, the F/M connection JM may be arranged below the lower horizontal bridge 57 . For example, the arrangement position of the F/M connection JM can be changed according to the required specifications.

In the above embodiment, the example in which the engine 10 is a single-cylinder engine has been described, but the present invention is not limited to this. For example, engine 10 may be a multi-cylinder engine. The engine 10 can adopt various forms.
