Fig. 6 is a sectional view taken along line VI-VI in fig. 4. Fig. 7 is a sectional view taken along line VII-VII in fig. 4. Fig. 8 is a sectional view taken along line VIII-VIII in fig. 4. Fig. 9 is a sectional view taken along line IX-IX in fig. 4.

Referring to fig. 5 to 9, the first edge main body portion 71a of the first edge portion 71 includes: a linear first ridge line portion 75 (ridge line portion) extending in the vehicle width direction; and a first inclined surface portion 76 (inclined surface portion) extending upward from a first lower surface portion 55a (lower surface portion) located below the first ridge line portion 75 on the surface 43a and connected to the first ridge line portion 75.

The first lower surface portion 55a is a surface of an upper portion of the main lamp body lens portion 55 and is a portion located below the first edge portion 71. The first lower surface portion 55a extends rearward and upward in a nearly vertical posture.

The first inclined surface portion 76 is inclined to tilt forward relative to the first lower surface portion 55a in a side view of the vehicle, and is closer to the vertical than the first lower surface portion 55 a.

For example, as shown in fig. 6, the first inclined surface portion 76 is inclined to the front side by an angle A1 from the first lower side surface portion 55 a.

As shown in fig. 5 to 9, the first ridge line portion 75 and the first inclined surface portion 76 are provided over the entire length of the first along body portion 71 a.

The upper and lower widths H1 (fig. 4) of the first inclined surface portion 76 are substantially the same in the entire vehicle width direction.

The angle of the surface 43a changes with the first ridge line portion 75 as a boundary. The first sub lamp body lens portions 56 above the first ridge line portions 75 are inclined to tilt rearward with respect to the first inclined surface portions 76 below the first ridge line portions 75, and the inclination is gentle.

The second edge portion 72 includes: a linear second ridge line portion 77 (ridge line portion) extending in the vehicle width direction; and a second inclined surface portion 78 (inclined surface portion) extending upward from the second lower side surface portion 58a (lower side surface portion) positioned below the second ridge portion 77 on the surface 43a and connected to the second ridge portion 77.

The second lower surface portion 58a is a surface of an upper portion of the second sub lamp body lens portion 58, and is a portion located below the second edge portion 72. The second lower surface portion 58a extends vertically in a nearly vertical posture.

The second inclined surface portion 78 is inclined forward and upward so as to be inclined forward relative to the second lower surface portion 58a when the vehicle is viewed in side elevation.

For example, as shown in fig. 6, the second inclined surface part 78 is inclined to the front side by an angle A2 than the second lower side surface part 58 a.

As shown in fig. 5 to 9, the second ridge portion 77 and the second inclined surface portion 78 are provided over the entire length of the second edge portion 72.

The upper and lower widths H2 (fig. 4) of the second inclined surface portion 78 are wider toward the vehicle width direction outer side.

The angle of the surface 43a changes with the second ridge portion 77 as a boundary. The main lamp body lens portion 55 above the second ridge line portion 77 is inclined so as to tilt rearward with respect to the second inclined surface portion 78 below the second ridge line portion 77.

Referring to fig. 4 and 9, a separating portion 73 is provided between an outer end 71c of the first extending portion 71a in the vehicle width direction and an outer end 72a of the second extending portion 72 in the vehicle width direction. The separating portion 73 is provided at an outer end portion of the main lamp body lens portion 55 in the vehicle width direction. The separating portion 73 is sandwiched between the end portion 71c and the end portion 72a in the vertical direction, and is open outward in the vehicle width direction from between the end portion 71c and the end portion 72 a.

The light L emitted from the main lamp part 50 passes through the inside of the cylindrical partition wall 60 and is emitted forward. Therefore, the partition wall 60 suppresses the influence of the emission light L on the emission light L1 of the first sub lamp body 51 above the main lamp body 50 and the emission light L2 of the second sub lamp body 52 below the main lamp body 50.

The partition wall 60 suppresses the influence of the emission light L1 of the first sub lamp body portion 51 on the emission light L of the main lamp body portion 50, and suppresses the influence of the emission light L2 of the second sub lamp body portion 52 on the emission light L of the main lamp body portion 50.

The first edge main body portion 71a functions to vertically divide the light emission L of the main lamp body portion 50 and the light emission L1 of the first sub lamp body portion 51. Since the first vertical main body portion 71a overlaps the partition wall 60 from the front, the interaction between the emission light L of the main lamp body portion 50 and the emission light L1 of the first sub lamp body portion 51 can be effectively suppressed. Therefore, the emission light L of the main lamp portion 50 and the emission light L1 of the first sub lamp portion 51 become clear, and the main lamp portion 50 and the first sub lamp portion 51 are visually confirmed well.

The second edge portion 72 functions to vertically divide the light emission L of the main lamp body portion 50 and the light emission L2 of the second sub lamp body portion 52. Since the second edge portion 72 overlaps the partition wall 60 from the front, the interaction between the emission light L of the main lamp body 50 and the emission light L2 of the second sub lamp body 52 can be effectively suppressed. Therefore, the light emission L of the main lamp portion 50 and the light emission L2 of the second sub lamp portion 52 are clear, and the main lamp portion 50 and the second sub lamp portion 52 are visually confirmed well.

Dirt such as muddy water may adhere to the surface 43a of the lens portion 43.

A part of the traveling wind flowing along the front surface 10a of the saddle-ride type vehicle 10 is a first traveling wind W1 (fig. 4) flowing toward the outside in the vehicle width direction below the first edge portion 71 along the first edge portion 71.

The upward movement of the first sub lamp body portion 51 of dirt adhering to the surface of the main lamp body lens portion 55 is suppressed by the first edge portion 71, and the dirt is separated from the surface 43a by flowing outward in the vehicle width direction by the first traveling wind W1 along the first edge portion 71. Therefore, contamination of the surface 43a of the lens portion 43 can be suppressed, and visibility from the perspective of the occupant of the headlamp 40 and visibility of the headlamp 40 can be improved.

Further, the first inclined surface portion 76 connecting the first lower surface portion 55a and the first ridge line portion 75 is inclined so as to incline forward with respect to the first lower surface portion 55 a. Thus, the first inclined surface portion 76 hinders dirt moving upward along the main lamp body lens portion 55, and therefore, dirt in the main lamp body lens portion 55 can be prevented from moving toward the first sub lamp body portion 51.

The dirt that flows outward in the vehicle width direction by the first traveling wind W1 along the first edge portion 71 flows outward in the vehicle width direction from the separating portion 73. Therefore, dirt can be smoothly discharged from the surface 43 a.

A part of the traveling wind flowing along the front surface 10a of the saddle type vehicle 10 is the second traveling wind W2 flowing toward the vehicle width traveling outer side below the second edge portion 72 along the second edge portion 72 (fig. 4).

The upward movement of the main lamp body lens portion 55 by the dirt adhering to the surface of the second sub lamp body lens portion 58 is suppressed by the second edge portion 72, and the dirt is separated from the surface 43a by flowing toward the vehicle width direction outer side by the second traveling wind W2 along the second edge portion 72. Therefore, contamination of the surface 43a of the lens portion 43 can be suppressed, and visibility from the perspective of the occupant by irradiation of the headlight 40 and visibility of the headlight 40 can be improved.

Further, the second inclined surface portion 78 connecting the second lower surface portion 58a and the second ridge portion 77 is inclined so as to fall forward with respect to the second lower surface portion 58 a.
