  In the case of the former conventional example, specifically, since a concave portion that is recessed upward is formed in the bottom plate of the sheet and the communication device is accommodated in the concave portion, it is difficult to secure a wide arrangement space for the communication device. The shape of the bottom plate of the sheet is also complicated. Also, the ride comfort is affected by the reduced thickness of the seat. Furthermore, since the upper part of the communication device is covered with a sheet, it becomes an obstacle to transmission and reception of radio waves with an artificial satellite or the like.

  In the latter conventional example, a communication device such as an anti-theft device is arranged in the vicinity of the rear end of the rear frame, so that the volume at the rear of the vehicle body increases, the design is impaired, and the weight balance between the front and rear of the entire vehicle It becomes difficult to take.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a motorcycle in which an arrangement space can be easily secured and a communication device for anti-theft measures can be arranged at a place where there is little influence on transmission and reception of radio waves.

  In order to solve the above-described problems, the present invention provides a main frame on which an engine is mounted, a rear frame extending rearward from the main frame, a seat supported by the rear frame, and left and right sides of the rear frame. In a motorcycle comprising a cowl that covers from the outside in the width direction, and a communication device that measures the position of the host vehicle and can wirelessly transmit the measured position information, the communication device has a vehicle width of the rear frame. It is arranged at one or both positions on the outer side in the direction, at a position where at least the upper side, the outer side in the vehicle width direction, and the lower side are covered by the cowl.

In addition to the above contents, the present invention can preferably have the following configuration.
(A) The support bracket that supports the communication device is fixed to the rear frame by a common bolt together with the seat bracket that supports the seat.

(B) The communication device is arranged such that an antenna for transmitting and receiving radio waves faces upward.

(C) The communication device is covered with an elastic member, and the elastic member is supported by the support bracket.

(D) The communication device is an anti-theft device, the anti-theft device is connected to a warning sound generating device, and the anti-theft device is connected to one of the rear frame members on the outer side in the vehicle width direction. It is a position, and is arranged at a position where at least the upper side, the outer side in the vehicle width direction and the lower side are covered by the cowl, and the warning sound generating device is arranged at the other position. In this case, preferably, the support bracket that supports the warning sound generating device is fixed to the rear frame by a common bolt together with the seat bracket.

(1) According to the present invention, since the communication device is disposed outside the rear frame in the vehicle width direction and is only covered with the cowl, it is easy to secure an arrangement space and obstructs transmission / reception of radio waves. Therefore, the transmission / reception performance is maintained well. In addition, since the communication device is disposed at the rear of the vehicle away from the engine, it is not easily affected by the heat of the engine.

(2) According to the configuration (a), since the seat bracket and the support bracket for the communication device are attached using a common bolt, the number of parts for attachment can be reduced, and the attachment work process can be reduced.

(3) According to the configuration (b), the transmission / reception performance is improved in the configuration in which the communication device transmits / receives data to / from the artificial satellite.

(4) According to the configuration (c), it is possible to prevent the vehicle body vibration from being transmitted to the communication device by the buffering action of the elastic member, and to prevent the communication device from being broken due to the vibration. Further, the communication device can be protected from the outside.

(5) When the communication device is an anti-theft device as in the configuration (d), the space on both sides of the rear frame can be effectively used for the arrangement of the anti-theft device and the warning sound generating device. Each space can be made smaller by distributing them to the left and right. Further, since the seat bracket and the warning sound generating device support bracket are attached with a common bolt, the number of attachment members can be reduced, and the number of steps for the attachment work can be reduced.
