JP 2000-108972 A

By the way, if the winker escape recess as described above is provided on the side surface of the front cowl, the rectifying surface behind the front winker is eliminated, so that the rectifying effect is lowered. In order to prevent such a decrease in the straightening area, it is conceivable that the front winker is supported directly on the side surface of the front cowl instead of the stay so as not to provide the winker escape recess.
However, if the front winker is directly supported on the flat side surface of the front cowl as in Patent Literature 1, the winch escape recess is eliminated in the front cowl and the rectifying effect is improved, but the front cowl is made of resin. In order to increase the rigidity of the part to which the front turn signal is attached, it is necessary to increase the weight and cost by partially increasing the wall thickness or adding a metal reinforcing plate.
Therefore, a support structure for a front winker that does not increase the weight and cost is desired, and the present application fulfills this demand.

In order to solve the above problem, the invention described in claim 1
A front cowl (15) that is provided at the front of the vehicle and supports the headlight (16) and a front blinker (17) that is fixed to a side surface of the front cowl. The front blinker (17) is a front cowl ( 15) In a saddle-ride type vehicle supported on an outer end portion of a support arm portion (37) extending outward in the vehicle width direction from the side surface of
A winker mounting protrusion (35) that protrudes outward in the vehicle width direction is integrally provided on a part of the side surface of the front cowl (15),
An inward end portion of the support arm portion (37) is coupled to the turn signal attaching projection (35).

The invention described in claim 2 includes a garnish (31) which is formed separately from the front cowl (15) and covers a side surface of the front cowl (15) in the above-mentioned claim 1,
A through hole (36) is provided in the garnish (31), and the blinker mounting protrusion (35) protrudes outward from the through hole (36).
The front cowl (15) and the support arm portion (37) have the same color.

According to a third aspect of the present invention, in the second aspect, the turn signal attachment projection (35) has a cylindrical shape, and a turn signal fastening member (38) is accommodated inside thereof.
The maximum protrusion amount (H1) of the turn signal attachment protrusion (35) from the side surface of the front cowl (15) is equal to the height (H2) of the turn signal fastening member (38) in the fastening shaft direction, and the inner diameter is It is equal to or larger than the outer diameter of the winker fastening member (38).

According to a fourth aspect of the present invention, in the third aspect, the support arm portion (37) has a cylindrical shape, and an outer diameter of an inner end portion in the vehicle width direction of the winker mounting protrusion (35). It is characterized by being equivalent to the outer diameter at the outer end.

According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the side surface of the front cowl (15), which is the rear of the winker mounting projection (35), has a winker rear rectifying surface ( 31a) is provided.

According to the first aspect of the present invention, the front turn signal is obtained by coupling the inner end portion of the support arm portion extending inward in the vehicle width direction to the turn signal attachment protrusion provided on the side surface of the front cowl. Since it is fixed to the side surface, the conventional winker escape recess is not required, and the rectification area is increased by at least the amount corresponding to the winker escape recess, thereby improving the rectification effect.
Further, since the turn signal attachment protrusion is formed by integrally protruding a part of the side surface of the front cowl to the outside in the vehicle width direction, the protrusion shape increases the rigidity. As a result, it is not necessary to increase the wall thickness or to reinforce with a metal plate, so that an increase in weight and cost can be suppressed.
In addition, since the front cowl and the support arm portion of the front turn signal are directly coupled, a sense of unity between the front cowl and the front turn signal can be obtained.
In addition, since the front blinker can be moved outward in the vehicle width direction by the amount that the blinker mounting protrusion protrudes outward in the vehicle width direction, the visibility to the front blinker is improved.

According to the invention of claim 2, since the garnish formed separately from the front cowl and overlapping the side surface is provided, and the winker mounting projection protrudes outward from the through hole of this garnish, the garnish is used as an external member, And it can be made into a baffle surface. Moreover, since the load of the front turn signal is not applied to the garnish, it can be formed into a thin wall.
In addition, the front winker's support arm and the front cowl are the same color (for example, black), and the surrounding area is covered with garnish, so the front winker's support arm and the front cowl are joined together to create a sense of incompatibility. In addition to being able to reduce, design effects such as two-tone colors are facilitated by garnish, and the appearance can be improved.

According to the invention of claim 3, the winker mounting protrusion is cylindrical, and the winker fastening member is accommodated inside thereof, and the maximum protrusion amount of the winker mounting protrusion is equal to the height of the winker fastening member in the fastening axis direction. Since the inner diameter is equal to or greater than the outer diameter of the turn signal fastening member, the entire turn signal fastening member can be accommodated in the cylindrical portion of the turn signal attachment projection. For this reason, since the winker fastening member does not protrude into the front cowl, the wiring in the front cowl in the vicinity of the winker mounting projection is not obstructed, and the degree of freedom of arrangement of other parts such as wiring is increased.

According to the invention of claim 4, the outer diameter of the inner end portion in the vehicle width direction of the cylindrical support arm portion is the same as the outer diameter of the outer end portion of the winker mounting projection that also has a cylindrical shape. In addition, a step does not occur in the joint portion between the support arm portion and the blinker mounting protrusion, and the uncomfortable feeling of the joint portion is reduced. In addition, it is possible to reduce the turbulence of the traveling wind in the vicinity of the joint.

According to the invention of claim 5, since the winker rear rectifying surface is provided on the side of the front cowl on the rear portion of the winker mounting projection, the rectifying area of the front cowl is enlarged behind the front winker, and the front cowl The rectifying effect can be improved.

The front wheel 13 is steered by a handle 14. The upper part of the front fork 12 is rotatably attached to the head pipe 11 via a top bridge 40 and a bottom bridge 41 (FIG. 2).

A front cowl 15 is supported in front of the head pipe 11, and a headlight 16 faces an opening formed on the front surface of the front cowl 15.
A meter 18 is disposed behind the headlight 16 and is supported toward the head pipe 11 side. The front of the meter 18 is covered with a screen 19. The screen 19 constitutes a part of the front cowl 15.

An engine 20 is supported on the body frame 10, a fuel tank 21 is supported above it, and a seat 22 is supported behind it.
A front end of the rear swing arm 23 is swingably supported at the rear portion of the vehicle body frame 10, and a rear wheel 24 is supported at the rear end of the rear swing arm 23.

Hereinafter, the mounting structure of the front cowl 15 and the front turn signal 17 will be described.
As shown in FIGS. 2 to 5, the front cowl 15 includes a cowl main body 30 that surrounds the headlight 16, a garnish 31 that is attached to the left and right sides thereof, and a screen 19 that is attached to the top of the headlight 16. And a headlight stay 32 for supporting the cowl body 30.

The headlight stay 32 has an upper portion 32a attached to the top bridge 40 with bolts 42, and a lower end portion 32b attached to the bottom bridge 41 with bolts 43 (see FIGS. 2 and 5).
The cowl main body 30 to which the headlight 16, the garnish 31 and the screen 19 are attached is supported by a headlight stay 32 that supports the meter 18. The headlight stay 32 accommodates and supports the meter 18 by a meter panel 33 (see FIGS. 2 and 4) at the upper end. The instrument panel 33 forms a cowl rear cover that covers the rear side of the front cowl 15.

The screen 19 has a rectifying surface that rises diagonally and extends rearward. The lower end of the screen 19 overlaps with the front upper portion of the cowl main body 30 and is supported here.
The screen 19, the cowl main body 30, the garnish 31, the headlight stay 32, and the meter panel 33 that constitute the front cowl 15 are all made of resin.

The cowl main body 30 has a frame shape surrounding the headlight 16 and is attached to the headlight stay 32. Therefore, the cowl body 30 is supported on the front fork 12 via the headlight stay 32 and rotates integrally with the front fork 12.

On both the left and right sides of the cowl main body 30, turn signal mounting bosses 35 projecting outward are integrally formed. The turn signal attachment boss 35 corresponds to the turn signal attachment protrusion of the present application, protrudes outward through a boss through hole 36 formed in the garnish 31, and extends to the vehicle body inner end of the support arm portion 37 of the front turn signal 17. The part is mounted. Therefore, the front turn signal 17 is directly attached to the side surface of the front cowl 15 via the support arm portion 37 and supported by the front cowl 15.

Thus, by integrally forming the turn signal attachment boss 35 on the side surface of the front cowl 15, the rigidity of the front cowl 15 in the vicinity of the turn signal attachment boss 35 can be increased, and the front turn signal 17 can be attached to the front cowl 15. It can be installed directly on the side. For this reason, it is not necessary to increase the thickness of the portion serving as the fixed portion of the front blinker 17 or to reinforce it with a metal plate, so that an increase in weight and cost can be suppressed.
In addition, by projecting the turn signal attachment boss 35 outward, even if the support arm portion 37 has the same length as that of the conventional case, the front turn signal 17 is arranged more outward, so that visibility is improved.

As shown in FIG. 6, the blinker mounting boss 35 has a hollow cylindrical shape, and the thickness thereof is the same as the thickness of the continuous general portion. A hexagon nut 38 for fixing the support arm portion 37 of the front winker 17 is accommodated in the hollow portion of the winker mounting boss 35. The hexagon nut 38 is the blinker fastening member of the present application. The hexagon nut 38 is fastened with a stud bolt 39 provided at the tip of the support arm portion 37 of the front winker 17.

The maximum protrusion amount of the turn signal mounting boss 35 (distance between the inner surface of the front cowl 15 serving as the base of the turn signal mounting boss 35 and the protruding end of the turn signal mounting boss 35) H1 is equal to or greater than the axial height H2 of the hexagon nut 38. is there.
Further, the outer diameter R1 of the inner end portion in the vehicle width direction of the cylindrical support arm portion 37 is substantially the same as the outer diameter R2 of the outer end portion of the winker mounting boss 35 having the same cylindrical shape. Yes.

As described above, if the outer diameters of the joint portions of the support arm portion 37 and the winker mounting boss 35 are the same, no step is generated in the joint portion of the support arm portion 37 and the winker mounting boss 35, and the uncomfortable feeling of the joint portion is reduced. To do. In addition, it is possible to reduce the turbulence of the traveling wind in the vicinity of the joint.

The inner diameter of the blinker mounting boss 35, which is the width of the space for accommodating the hexagon nut 38, is equal to or greater than the outer diameter of the hexagon nut 38, and the hexagon nut 38 can be easily inserted and removed. Thus, by making the inside of the turn signal mounting boss 35 to be equal to or larger than the size of the hex nut 38, the entire hex nut 38 is accommodated in the turn signal mounting boss 35 and protrudes to the inner surface side of the front cowl 15. Absent.

FIG. 6 is a cross-sectional view schematically showing that the winker mounting boss 35 has a cylindrical shape. Actually, as shown in FIG. 5, the winker mounting boss 35 is not completely cylindrical, and the protruding height of the peripheral wall. Is an irregular shape that changes in the circumferential direction, and the peripheral wall is slightly inclined in a tapering manner in the protruding direction. However, as is clear in either FIG. 5 or FIG. 6 and FIG. 7, the inner diameter of the winker mounting boss 35 is larger than the outer diameter of the hexagon nut 38, and Easy to put in and out.

The tip of the stud bolt 39 attached to the hex nut 38 is also set so as not to protrude into the front cowl 15. The stud bolt 39 and the support arm portion 37 are hollow, and the winker wiring 44 extending from the front winker 17 passes through the hollow portion. The turn signal wiring 44 enters the inside of the cowl main body 30, that is, the inside space of the front cowl 15 from the inner opening 35 a of the turn signal attachment boss 35.

Many other parts such as various harnesses and electrical parts are arranged inside the front cowl 15. Reference numeral 45 in FIG. 5 is a harness connected to the meter 18 and the like, and 46 is a waterproof boot of the wiring joint portion.
As described above, if the hexagon nut 38 and the stud bolt 39 are not protruded to the inside of the cowl main body 30, the winker wiring 44 disposed in the inner space of the front cowl 15 in the vicinity of the winker mounting boss 35 and the like. Therefore, the wiring inside the front cowl 15 is easy, and the degree of freedom of arrangement of the wiring and other parts is increased.

The garnish 31 is a decorative member that covers the side surface of the cowl main body 30 and also a member that rectifies traveling wind, and has a smooth curved surface with the surface as a rectifying surface. The garnish 31 extends rearward from the winker mounting boss 35 and increases the area of the rectifying surface to increase the rectifying effect (FIG. 2).
Moreover, since the garnish 31 does not support the front turn signal 17, it is not necessary to make it highly rigid, and a relatively thin member is sufficient, which can contribute to weight reduction of the vehicle.

Furthermore, since the garnish 31 is a decorative member, it can be arbitrarily colored to enhance the appearance. For example, the front blinker 17 includes the support arm portion 37 and is black as the vehicle body color, and the cowl main body portion 30 that is not an appearance member is also black. Thereby, when the front turn signal 17 is attached to the front cowl 15, the support arm portion 37 and the turn signal attachment boss 35 are connected in the same color, and the sense of unity can be enhanced. In addition, since the outer diameters of the winker mounting boss 35 and the base portion of the supporting arm portion 37 in the vicinity thereof also match, it is possible to achieve a more unity connection.

On the other hand, by making the garnish 31 an arbitrary color different from black, the front cowl 15 can be made into a two-tone color or the like, so that the design effect can be facilitated, the design effect can be enhanced, and the appearance can be improved. .
Further, by making the support arm portion 37 and the turn signal attachment boss 35 have the same diameter, it is possible to eliminate irregularities in the outer peripheral portion, thereby making it easy to maintain the rectifying effect around the turn signal attachment boss 35. In addition, since a sense of unity at the joint between the support arm 37 and the blinker mounting boss 35 is obtained, the sense of incongruity at the joint is eliminated.

Further, since the turn signal attachment boss 35 penetrates the boss through hole 36 formed in the garnish 31, the garnish 31 extends rearward from the boss through hole 36. Therefore, unlike the prior art, in order to escape the support arm portion 37, it is not necessary to form an escape recess (portion indicated by reference numeral 50 in FIG. 2) that is recessed to the front of the base portion of the support arm portion 37. The rectifying surface at the rear can be enlarged.

In FIG. 2, reference numeral 50 indicated by an imaginary line is a winker escape recess that has been conventionally formed.
In the present invention, there is no portion corresponding to the winker escape recess 50, and a rear portion of the side surface of the cowl main body 30 extends from the winker mounting boss 35 as a winker rear portion 30 a. Further, the winker rear portion 30 a is covered with a garnish 31.
The rear part of the garnish 31 from the turn signal attachment boss 35 forms a turn signal rear rectifying surface 31a, and the rear part of the front turn signal 17 can be widely rectified.
As shown in FIGS. 2 and 7, the winker rear rectifying surface 31 a extends rearward longer than the rear end edge 30 b of the winker rear portion 30 a to form a wide rectifying area.

The present invention is not limited to the above-described embodiment, and various modifications and applications are possible within the principle of the invention. For example, the hexagon nut 38 is not limited to a hexagon, and can be a fastening member such as a nut having various shapes. Further, although the headlight stay 32 is attached to the front fork 12 side, it may be attached directly to the head pipe 11 side.
Further, the winker rear rectifying surface 31a is provided on the garnish 31, but the winker rear rectifying surface 30a on the side surface of the cowl main body 30 may be exposed instead of the garnish 31, and this may be used as the winker rear rectifying surface.
