This allows further downsizing and weight reduction of the flash lamp 7 and the rear cover 40. By increasing the support rigidity at a position inside the rear cover 40, the appearance of the saddle riding type vehicle 1 is not impaired. Further, since the stay member 50 does not need to be formed in an elliptical cross section or other shape to prevent rotation, design flexibility of the flash lamp 7 can be improved by assuming, for example, a circular cross section for the stay member 50.The headlight stay S of the saddle riding type vehicle 1 is supported on the vehicle body side in front of the head pipe F 1 constituting the vehicle frame F and supports the headlight 11; and the bracket mounting portion 96 is part of the headlight stay S, whereby the stay member 50 is fixed to the headlight stay S supported on the vehicle body side, and the rigidity and precision in mounting the stay member 50 can be increased without the need for additional components.The headlight stay S includes the rear cover mounting portion 97 that supports the rear cover 40; the bracket mounting portion 96 is continuous with the rear cover mounting portion 97 that extends outward in the vehicle width direction and is shaped to bend around from above to the front of the rear cover mounting portion; and the bracket 60 is fixed to the bracket mounting portion 96 at the front of the bracket 60. Therefore, the bracket 60 and the rear cover 40 can be fixed to the headlight stay S without the need for additional mounting components. The rear cover mounting portion 97 is disposed close to the holder mounting portion 96, thereby making it possible to reduce the risk of misalignment between the rear cover 40 and the brace member 50.The support member 150 that holds the wire harness H supplying power to the light source 56 is mounted on the connection portion 98 that connects the rear cover mounting portion 97 and the holder mounting portion 96. Therefore, the harness supporting member 150 is disposed between the rear cover mounting portion 97 and the holder mounting portion 96, thereby making it possible to efficiently use dead space and protect the harness H.The vehicle includes: the front fork 13 supporting the front wheel WF and rotatably supported by the head pipe F 1; the upper bridge 6 supporting the front fork 13 above the head pipe F 1; and the lower bridge 12 supporting the front fork 13 below the head pipe F 1. The headlight stay S is composed of the upper member 80 and the lower member 90, the upper member 80 being supported by the upper bridge 6, and the lower member 90 being supported by the lower bridge 12. The upper member 80 and the lower member 90 are fixed together by connecting the upper connecting portion 81 of the upper member 80 and the lower connecting portion 99 of the lower member 90. Therefore, by partitioning the complex-shaped headlight stay S into the upper and lower portions, manufacturing cost can be reduced, and the ease of attachment to the vehicle body can be increased. The headlight stay S is supported with the rigid body, i.e., the upper bridge 6 and the lower bridge 12, so that the precision in assembling the flasher lamp 7 and the rear cover 40 can be further improved.In a side view of the vehicle body, at least a part of the rear cover mounting portion 97 overlaps with the brace member 50, thereby allowing downsizing of the support structure for the brace member 50.In a plan view of the vehicle body, the holder mounting portion 96, the rear cover mounting portion 97, the upper connecting portion 81, and the lower connecting portion 99 are positioned within the space between the front edge L 1 contacting the front end of the flasher lamp 7 and the rear edge L 2 contacting the rear end of the flasher lamp 7. Therefore, the mounting portions are disposed close to each other in the front-rear direction, thereby allowing the front-rear dimensions to be reduced and the rear cover 40 and the flash lamp 7 to be stably supported.Further, the main body portion 70 of the holder 60 includes the protrusion 68 protruding forward from the main body portion 70, the engagement hole 69 for engaging with the locking member 52 is formed in the protrusion 68, and the stay member 50 includes the fitting hole 59 into which the protrusion 68 fits. Therefore, by fitting the protrusion 68 of the holder 60 into the fitting hole 59 of the stay member 50, the precision in mounting the flash lamp 7 can be further improved.The configuration and shape of the motorcycle, the flash lamp, the stay member, the bracket, the rear cover, the front cowl, and the headlight stay are not limited to the above embodiment and may be variously modified. For example, the holder may be configured with a tubular main body portion including a protrusion directly provided thereon without a holder bulging portion. The light source support structure of the saddle-riding type vehicle according to the present invention can be applied not only to motorcycle but also to three-wheeler, four-wheeler and various other saddle-riding type vehicles. Further, the present invention is not limited to front direction indicators, and may also be applied to rear direction indicators.Explanation of Reference Numerals1 Motorcycle (saddle riding type vehicle) 6 Upper bridge 7 Front flasher lamp (flasher lamp) 7 b Housing 10 Front cowl 10 aOpen 11 Headlight 12 Lower bridge 13 Front fork 40 Rear cover (external component) 41 aMount hole 50 Stay member 52 Locking member 56 Light source 57 One end of the stay member 58 Other end of the stay member 59 Fitting hole 60 Holder 68 Protrusion 69 Engagement hole 70 Main body portion of the holder 80 Upper member 81 Upper connection portion 90 Lower member 96 Holder mounting portion 97 Rear cover mounting portion 98 Connection portion 99 Lower connection portion 150 Support member F Vehicle frame F 1 Head pipe S Headlight stay WF Front wheel H Harness L 1 Front edge, which front end of the flash lamp contacts L2 rear edge which contacts rear end of the flash lampTo provide a saddle riding type vehicle that improves precision and rigidity in mounting the stay member of the flash lamp, thereby allowing further downsizing and weight reduction of the external component and the flash lamp.
