  The attachment portion of the license plate described in Patent Literature 1 is provided with the attachment piece protruding left and right in a cantilever shape on the front surface of the front cover. Needs to be enlarged. For this reason, when the above-mentioned structure is adopted, the attached member (front cover) of the vehicle is increased in size, and the appearance of the vehicle is likely to be impaired.

  Further, in the attachment portion of the license plate described in Patent Document 2, the upper edge portion of the license plate is fastened and fixed to the left and right attachment pieces, while the lower edge portion of the license plate is pressed against the protrusion. I have. Therefore, when the above-described structure is employed, the support rigidity of the license plate is increased, and the deflection of the license plate can be suppressed. However, when the above-described structure is employed, it is necessary to provide a projection on the mounted member (front cover) of the vehicle separately from the mounting piece, so that the structure of the mounted member is complicated.

  An aspect of the present invention provides a license plate mounting portion structure for a saddle-ride type vehicle, which can suppress the deflection of a license plate with a simple configuration and can also enhance the appearance and design of the vehicle.

The license plate structure of the saddle-ride type vehicle according to the present invention employs the following configuration in order to solve the above problems.
(1) A license plate mounting portion structure for a saddle-ride type vehicle according to one aspect of the present invention includes a support seat for supporting a back surface of the license plate, and the mounted member includes a rear surface extending from a flat portion of the license plate. A mounting hole into which a shaft protruding to the side is inserted is provided, the support seat is provided around the mounting hole of the mounted member, and inside the outer edge portion of the support seat, When the shaft portion is drawn inward in the axial direction of the mounting hole and fixed to the member to be mounted, a deformation allowance concave portion is provided that allows the number plate to bend and deform as the shaft portion is pulled in.

  According to the above configuration (1), when the license plate is mounted on the member to be mounted on the vehicle, a shaft protruding from the rear surface of the flat portion of the license plate is inserted into the mounting hole of the member to be mounted. In this state, the shaft portion is pulled inward in the axial direction of the mounting hole, and in this state, the shaft portion is fixed to the member to be mounted by appropriate fixing means. As a result, the flat portion of the license plate is pulled by the shaft portion, and the flat portion bends and deforms in the deformation allowable concave portion. The back surface of the license plate is pressed against the support seat in a state where the license plate is bent into a predetermined shape and tension is applied from the shaft portion. As a result, the license plate is prevented from oscillating by the applied tension, and is attached to the attached member in that state.

  (2) In the above aspect (1), the mounted member includes a substantially cylindrical boss protruding from the outer surface of the mounted member to the outside of the vehicle, and the support seat is formed on an end surface of the boss. A collar member that holds the shaft by inserting a first end into the mounting hole may be mounted inside the boss.

  In the case of the above aspect (2), since the attached member is provided with a substantially cylindrical boss protruding to the outside of the vehicle, and a support seat is formed on an end surface of the boss, the outer shape of the attached member is reduced. The license plate can be stably held by the boss portion without being affected. For this reason, the degree of freedom of the outer shape of the attached member can be increased. In addition, since the collar member holding the shaft portion is attached inside the substantially cylindrical boss portion, when the shaft portion is pulled into the inside of the mounting hole and fixed, stress concentration occurs on the end face of the boss portion. It becomes difficult. For this reason, the boss can be easily formed of the resin material.

  (3) In the aspect of (2), the collar member has a locking claw projecting outward in the radial direction, and the boss portion is locked with the locking claw inserted from the inside. A configuration having a locking groove may be used.

  In the case of the above mode (3), the collar member is inserted into the inside of the boss portion, and the locking claw of the collar member is locked in the locking groove of the boss portion in this state, so that the collar member can be easily attached to the boss portion. Can be attached to Further, the detachment of the collar member from the boss portion can be restricted by the engagement between the locking claw and the locking groove.

  (4) In the aspect of the above (2), the collar member has a flange wall protruding radially outward, and the boss portion protrudes toward the inside of a side wall of the boss portion to form the flange wall. A configuration having a stopper claw to be locked may be employed.

  In the case of the above mode (4), the collar member is inserted into the inside of the side wall of the boss portion, and the flange wall of the collar member is pushed into the boss portion over the disengagement control claw. Thereby, the collar member is easily attached to the boss portion, and the removal of the collar member is regulated by the removal control claw.

  (5) In the aspect according to any one of (2) to (4), the support seat is formed by a flat surface, and an end surface of the collar member on a first end side is in an axial direction of the mounting hole. May be disposed lower than the outer end of the collar member, and the deformation allowable concave portion may be constituted by the mounting hole and the end surface of the collar member.

  In the case of the above mode (5), the amount of retraction of the shaft portion when the license plate is mounted can be limited by the position of the end face of the collar member in the mounting hole. For this reason, the tension acting on the license plate can be easily adjusted by replacing the color member with a different specification.

  (6) In the aspect according to any one of the above (1) to (4), the support seat and the deformation-allowable concave portion are formed by an inclined concave surface which is continuously inclined from an outer peripheral edge portion to the mounting hole. It may be configured.

  In the case of the above mode (6), when the shaft portion is pulled into the mounting hole when the license plate is mounted, the inclined concave surface serving as the support seat comes into contact with the back surface of the license plate with a large area. Therefore, a stable tension can be generated on the license plate, and the license plate can be stably supported on the support seat.

  (7) In the aspect according to any one of the above (1) to (4), the support seat is formed by an inclined recess surface which is recessed while being inclined from an outer peripheral edge portion toward the mounting hole, and wherein the inclined recess is formed. A step-shaped recessed portion that is recessed in a step shape may be provided inside the surface, and the deformation allowable recess may be configured by the inclined recessed surface and the stepped recessed portion.

  In the case of the above mode (7), since the stepped recess is provided inside the inclined recessed surface serving as the support seat, when the shaft is pulled into the mounting hole when the license plate is mounted, the license plate is stepped. The depression is deeply formed in the shape of the concave portion, so that a strong tension is easily generated by the license plate. Therefore, it is possible to further suppress the deflection of the license plate.

  (8) In the above aspect (6) or (7), a plurality of fine concave portions may be formed on the inclined concave surface.

  In the case of the above mode (8), when the license plate attached to the attached member tries to vibrate due to running vibration or engine vibration, the air in the concave portion functions to suppress the vibration. Therefore, when the configuration is adopted, the vibration of the license plate can be suppressed.

  (9) In the aspect according to any one of (1) to (8), the attached member is a cover member of a vehicle larger than the license plate, and the license plate is attached to the cover member by rivets. You may make it fixed.

  In the case of the above mode (9), since the license plate is attached to the member to be mounted with rivets that are difficult to remove, and the member to be mounted is constituted by a large cover member that is difficult to take out, the number plate is stolen from the vehicle. Can be suppressed.

  (10) In the aspect according to any one of (2) to (4), a female screw with which the shaft portion is screwed may be formed on an inner surface of the collar member.

  In the case of the above mode (10), since a female screw is formed on the collar member itself, it is not necessary to separately provide a nut. Therefore, in this case, the license plate can be fixed to the member to be mounted with a simple configuration capable of suppressing an increase in the number of components.

  (11) In the aspect according to any one of the above (2) to (4), the boss portion may be formed in a polygonal shape as viewed from a projecting direction of the boss portion.

  In the case of the above mode (11), the plurality of corners of the boss can easily provide directivity to the tension applied to the license plate.

  (12) In the aspect according to any one of the above (2) to (4), the attached member is a cover member made of a resin of a vehicle, and is separated from the boss in an outer surface side in a vehicle width direction. A plurality of portions are provided, and a plurality of reinforcing ribs are provided on the back surface side. The reinforcing rib is provided between a first reinforcing rib extending in a direction connecting adjacent boss portions and an adjacent boss portion. A configuration having an inclined rib along a direction obliquely intersecting with the connecting direction may be employed.

  In the case of the above aspect (12), the back surface side of the cover member is reinforced by the first reinforcing ribs and the inclined ribs, and the bending rigidity and the torsional rigidity of the cover member are increased.

  (13) In the aspect of (12), a region between the adjacent boss portions of the cover member may have a shape that is convexly curved in a protruding direction of the boss portion.

  In the case of the above (13), the bending rigidity and the torsional rigidity of the curved portion between the adjacent bosses of the cover member are effectively increased by the first reinforcing rib and the inclined rib. For this reason, when the load accompanying the retraction of the shaft portion is input to the cover member when the license plate is fixed, the deformation of the cover member due to the input load is effectively suppressed by the first reinforcing rib and the inclined rib. Can be.

  According to the aspect of the present invention, the deformation-permissible concave portion is provided inside the outer edge portion of the support seat that supports the back surface of the license plate, and the shaft portion of the license plate is drawn into the inside of the mounting hole and fixed to the mounted member. Sometimes, the deformation of the license plate due to the retraction of the shaft portion is allowed by the deformation allowing recess. Therefore, the license plate can be attached to the member to be attached in a state where a part of the license plate is bent into a predetermined shape and tension is applied. Therefore, according to the present invention, the support rigidity of the license plate can be increased while suppressing the complexity and size of the attached member. And since the attachment member can be suppressed from becoming complicated and large, the appearance and design of the vehicle can also be improved.

FIG. 7 is a cross-sectional view similar to FIG. 5 showing how the license plate 19 is riveted to the boss 21 of the front center cover 16. FIG. 8 is a sectional view similar to FIG. 5 showing a state in which the license plate 19 is riveted to the boss portion 21 of the front center cover 16. 7 and 8, the license plate 19 is indicated by a virtual line.
Here, the rivet 22 used for fixing the license plate 19 is a blind rivet. As shown in FIG. 7, the rivet 22 includes a flange portion 22 b (head) that contacts the front surface of the license plate 19, A sleeve 22c protruding from the portion 22b to one side in the axial direction, and integrally connected to the protruding end of the sleeve 22c, and inserted into the sleeve 22c and the other end protruding from the flange portion 22b to the other side in the axial direction. Mandrel 22d. The sleeve 22c constitutes the shaft 22a of the rivet 22.

  When the license plate 19 is actually riveted to the boss portion 21, the license plate 19 is placed on the left and right boss portions 21, and the shaft portion 22a (sleeve 22c) of the rivet 22 is inserted into the corresponding rivet of the license plate 19. It is inserted into the hole 19 a and the mounting hole 23 of the boss 21. At this time, the shaft portion 22a (sleeve 22c) of the rivet 22 is inserted into the cylindrical wall 28b of the collar member 28 previously assembled to the boss portion 21. The tip of the shaft 22a (sleeve 22c) penetrates downward through the cylindrical wall 28b of the collar member 28.

Next, in this state, the mandrel 22d of the rivet 22 protruding upward from the flange portion 22b is pulled in by a special tool, thereby applying a pulling load to the tip of the sleeve 22c to plastically deform the tip of the sleeve 22c. Let it. As a result, the distal end of the sleeve 22c is crushed in the axial direction and swells and deforms radially outward in a flange shape. Hereinafter, the swelled and deformed portion is referred to as a “swelled flange 22e”. At this time, the mandrel 22d of the rivet 22 is pulled out from the sleeve 22c or cut off.
As a result, the flange portion 22b and the swelling flange 22e of the rivet 22 firmly sandwich the license plate 19 and the cylindrical wall 28b of the collar member 28, and the license plate 19 is pressed against the inclined recessed surface 24 of the boss portion 21 and is pressed. It will be fixed to the boss 21.

  When the rivet 22 is swaged by the dedicated jig as described above, a swelling flange 22e is formed at one end of the rivet 22, and the swelling flange 22e contacts the lower end of the cylindrical wall 28b of the collar member 28. At this time, the shaft portion 22a (the upper region of the shaft portion 22a) of the rivet 22 is guided downward by the cylindrical wall 28b of the collar member 28 (toward the inside of the mounting hole 23 in the axial direction). Thus, the flange portion 22b of the rivet 22 presses the peripheral portion of the rivet insertion hole 19a of the license plate 19 downward from the outer surface side. At this time, the peripheral edge of the rivet insertion hole 19a of the license plate 19 is pulled downward in the step-shaped recess 25 on the boss 21, and the license plate 19 makes the back surface abut the entire inclined recess surface 24. Bends as follows.

An area and a step-like depression 25 are provided. When the rivet is fastened to the rivet 22, the inclined deformation surface 24 and the step-shaped depression 25 allow the deformation of the license plate 19 due to the retraction of the shaft portion 22 a of the rivet 22. For this reason, the license plate 19 can be attached to the front center cover 16 in a state where a part of the license plate 19 is bent into a predetermined shape and tension is applied.
Therefore, when the structure of the license plate attaching portion 20 of the present embodiment is employed, the rigidity of supporting the license plate 19 can be increased while suppressing the complexity and size of the front center cover 16 as the attached member. . When this structure is employed, the complexity and size of the front center cover 16 can be suppressed, so that the appearance and design of the vehicle can be enhanced.

  In the license plate attaching portion 20 of the present embodiment, a substantially cylindrical boss portion 21 protruding outward from the vehicle is provided on the front center cover 16 as a member to be attached, and a support seat is provided on an end surface of the boss portion 21. An inclined recessed surface 24 is formed. For this reason, the license plate 19 can be stably held by the boss portion 21 without being affected by the outer shape of the front center cover 16 that is three-dimensionally curved. Therefore, when the structure of the license plate attaching portion 20 of the present embodiment is adopted, the degree of freedom of the outer shape of the front center cover 16 can be increased.

  Further, in the license plate mounting portion 20 of the present embodiment, a collar member 28 that holds the shaft portion 22a of the rivet 22 is mounted inside a substantially cylindrical boss portion 21. Therefore, when the shaft portion 22a of the rivet 22 is pulled into the inside of the mounting hole 23 to fix the license plate 19, stress is less likely to be concentrated on the end face of the boss portion 21. Therefore, when the structure of the license plate attaching portion 20 of the present embodiment is adopted, the boss portion 21 can be easily formed of a resin material.

  The license plate attaching portion 20 of the present embodiment is provided with a locking claw 28a protruding radially outward on the collar member 28, and provided on the boss portion 21 when the collar member 28 is inserted into the boss portion 21.

For this reason, it is difficult to remove the riveted license plate 19 from the front center cover 16, and since the front center cover 16 is a large part, it is also difficult to remove the front center cover 16 from the vehicle and take it out. Therefore, when this structure is adopted, the theft of the license plate 19 from the vehicle can be suppressed.

  Further, in the license plate attaching portion 20 of the present embodiment, the boss portion 21 that supports the back surface of the license plate 19 at the end face is formed in a quadrangular shape that is irregular when viewed from the projecting direction. The directivity can be easily given to the tension applied to the license plate 19 by the corners. Therefore, when this structure is employed, tension can be easily applied to a desired region on the license plate 19. In the present embodiment, the shape of the boss portion 21 as viewed from the protruding direction is a square shape, but the shape of the boss portion 21 is another polygonal shape such as a triangular shape other than the square shape or a pentagonal shape. May be.

  Further, in the present embodiment, on the back surface of the front center cover 16, which is a resin cover member, the first reinforcing rib 29 a along the direction connecting the adjacent bosses 21 and the space between the adjacent bosses 21 are provided. A plurality of reinforcing ribs including a slanting rib 29c extending in a direction obliquely intersecting with the connecting direction are protruded. For this reason, the bending rigidity and the torsional rigidity of the region between the left and right boss portions 21 of the front center cover 16 can be efficiently increased by the first reinforcing ribs 29a and the inclined ribs 29c.

  In particular, in the case of a cover member having a shape curved convexly toward the protruding direction of the boss portion 21 in a region between the left and right boss portions 21 like the front center cover 16 of the present embodiment, Even when a large load is input to the left and right boss portions 21 through the rivets 22 at the time of fixing, the warpage of the front center cover 16 due to the input load can be effectively suppressed.
