[0024] The fork member 51 is attached to the top bridge 52 by fastening a bolt 55 to the split groove at the upper end of the fork member 51. The upper end of a stem pipe 54 is fixed to the top bridge 52 by a stem nut 56. The fork member 51 is fixed to the bottom bridge 53 by fastening a bolt 57 from the front into a split groove (not shown). The lower end of a stem pipe 54 is supported at the left-right center of the bottom bridge 53.

[0025] A pair of left and right handle posts 58 are provided on the top bridge 52. The handle posts 58 support the handles 21. A mirror 59 is supported on the handle bars 21a of the handles 21.

[0026] Fig. 3 is a left side view of the headlight unit 60. Fig. 4 is a perspective view of the headlight unit 60 from above. Fig. 5 is a rear view of the headlight unit 60. Fig. 6 is a bottom view of the headlight unit 60. A headlight unit 60 is supported in front of the front fork 14.

[0027] The headlight unit 60 has a main body portion (headlight body) of the headlight 41 having an electric board on which a light source is arranged, a meter unit 44 arranged on the upper part of the main body portion, and a front cowl 31 that covers the main body portion of the headlight 41.

[0028] The front cowl 31 comprises a front cowl main body 61 that covers the light source portion of the headlight 41 from the front, a front upper cover 62 that is disposed on the upper part of the front cowl main body 61 and covers the meter unit 44 from above, and a headlight rear cover 63 that is disposed behind the front cowl main body 61 and the front upper cover 62 and covers the main body portion of the headlight 41 from the rear.

[0029] An opening 61a is formed in the front cowl body 61 in correspondence with the front of the light source portion of the headlight 41. An outer lens 41a through which light from the light source portion of the headlight 41 passes is supported in the opening 61a.

[0030] An opening 62a is formed in the front upper cover 62 to expose the meter unit 44 upward. The meter unit 44 is attached to the opening 62a from below. The meter unit 44 is visible to the driver through the opening 62a. A circular cylinder hole 62b penetrating in the up-down direction is formed behind the opening 62a. The cylinder hole 62b is formed in the left-right center of the front upper cover 62.

[0031] A lock mechanism (handle lock mechanism) 70 is disposed below the cylinder hole 62b. The lock mechanism 70 is fixed to the top bridge 52. The lock mechanism 70 is disposed in front of the head pipe 18. The lock mechanism 70 has a cylindrical key cylinder portion 71 that extends in the vertical direction, and a lock mechanism main body portion 72 that is provided below the key cylinder portion 71 and has a larger diameter than the key cylinder portion 71.

[0032] A piece-shaped support plate portion 73 that protrudes rearward is formed between the key cylinder portion 71 and the lock mechanism main body portion 72. A pair of support plate portions 73 are formed on the left and right sides of the key cylinder portion 71. A bolt 73a is inserted into the support plate portion 73 from below. The bolt 73a is fastened to the underside of the top bridge 52. This allows the lock mechanism 70 to rotate integrally with the front fork 14 in front of the head pipe 18. The lock mechanism 70 is disposed in the center in the vehicle width direction. The lock mechanism 70 rotates on the front outer periphery side of the head pipe 18.

[0033] A key insertion portion 71a is formed on the upper portion of the key cylinder portion 71. The key insertion portion 71a is attached from below into the cylinder hole 62b of the front upper cover 62. A key (not shown) is inserted from above into the key insertion portion 71a.

[0034] A rear surface 72a facing the head pipe 18 is formed in the vehicle width direction center of the lock mechanism main body 72 of the lock mechanism 70. The rear surface 72a is a flat surface. A pin hole 72a1 extending upward toward the front from the rear surface 72a is formed in the rear surface 72a. The pin hole 72a1 is formed in the left-right center. A lock pin 72b (see FIG. 4) is slidably supported in the pin hole 72a1. The lock pin 72b is linked to the operation of the key inserted in the key cylinder portion 71. The lock pin 72b is configured to be movable between a locked position where it protrudes rearward from the pin hole 72a1 and an unlocked position where it is recessed in the pin hole 72a1.

[0035] A cable 74 extends from below the lock mechanism main body 72. After extending downward, the cable 74 is routed to the right and routed inside the front cowl 31. The cable 74 is connected to the key cylinder portion 71.

[0036] 5, top bridge fixing portions 63a are formed on both the left and right sides of the lock mechanism 70 in the headlight rear cover 63. The top bridge fixing portions 63a are fixed to the rear top bridge 52 by bolts 63b extending from the front. Furthermore, a pair of left and right bottom bridge fixing portions 63c are formed on the lower end portion of the headlight rear cover 63. The bottom bridge fixing portions 63c are fixed to the bottom bridge 53 by bolts 63d extending from the front to the rear.

[0037] The top bridge fixing portion 63a and the bottom bridge fixing portion 63c in this embodiment are disposed between the pair of fork members 51. The headlight unit 60 is integrated with the front fork 14 by the top bridge fixing portion 63a and the bottom bridge fixing portion 63c. The headlight unit 60 is supported rotatably integrally with the front fork 14.

[0038] A protection rib (pin protection rib) 80 protruding rearward is formed on both the left and right sides of the lock mechanism 70 below the top bridge fixing portion 63a. The protection rib 80 is integrally formed on the rear surface of the headlight rear cover 63. Thus, the protection rib 80 is made of resin, similar to the headlight rear cover 63. The protection rib 80 is formed corresponding to the left and right sides of the lock mechanism 70. Thus, the key cylinder portion 71 and the lock mechanism main body portion 72 of the lock mechanism 70 are located between the left protection rib 80 and the right protection rib 80. The protection rib 80 is a curved plate shape protruding rearward. In this embodiment, the protection rib 80 is formed at the same height as the pin hole 72a1 of the lock mechanism main body portion 72. The protection rib 80 overlaps with the rear surface 72a of the lock mechanism main body portion 72 in a side view of the vehicle body (see FIG. 3). The protection rib 80 overlaps with the lock pin 72b protruding from the rear surface 72a in a side view of the vehicle body. In this embodiment, it overlaps with the front portion of the lock pin 72b.

[0039] The protective rib 80 has an upper edge portion 81 forming an upper edge, a lower edge portion 82 forming a lower edge, and a rear edge portion 83 forming a rear edge, in a side view of the vehicle body. The upper edge portion 81 extends rearward and downward from the rear surface of the headlight rear cover 63, in a side view of the vehicle body. The lower edge portion 82 extends rearward and upward from below the upper edge portion 81, in a side view of the vehicle body. The rear edge portion 83 is formed between the rear end of the upper edge portion 81 and the rear end of the lower edge portion 82. The rear edge portion 83 extends in the vertical direction. The rear edge portion 83 is inclined along the inclination of the head pipe 18. In the front-rear direction portion where the upper edge portion 81 is formed, the protective rib 80 has a vertical width that becomes smaller toward the rear. Compared to the vertical width of a front portion (front portion in the front-rear direction of the vehicle body) 80a of the protective rib 80, the vertical width of a rear portion (rear portion in the front-rear direction of the vehicle body) 80b is narrower.

[0040] The lower edge 82 of the protective rib 80 curves inward in the vehicle width direction as it progresses downward. The lower edge 82 curves convexly outward in the vehicle width direction. In a bottom view, the lower edge 82 curves from the outer side in the vehicle width direction to the inner side in the vehicle width direction. Therefore, when the clutch cable 102 moves from the outer side in the vehicle width direction and contacts the periphery of the lower edge 82 of the protective rib 80 during steering of the front fork 14, the contact surface of the protective rib 80 has a rounded curved shape, so that the protective rib 80 is less likely to damage the clutch cable 102, making it easier to use the clutch cable 102 for a long period of time.

[0041] FIG. 7 is a left side view showing the periphery of the top bridge 52. As shown in FIG. A lock pin receiving portion 90 is formed at the upper end of the head pipe 18. The lock pin receiving portion 90 is made of metal. The lock pin receiving portion 90 includes a semi-cylindrical main body portion 91 having a diameter larger than the outer diameter of the head pipe 18, and a base portion 92 formed at the lower end of the main body portion 91 and connected to the head pipe 18. The base portion 92 is fixed to the outer periphery of the head pipe 18. The base portion 92 is fixed at an incline along a direction perpendicular to the inclination direction of the head pipe 18. In this embodiment, the base portion 92 constitutes the lower end of the lock pin receiving portion 90. A pair of pin engagement openings 91a are formed on the left and right sides of the main body portion 91. The pin engagement openings 91a are formed to have an opening width large enough to allow the lock pin 72b to be inserted therein. In this embodiment, the main body portion 91 is cut out downward from the upper end thereof in a substantially U-shaped shape. The pin engagement opening 91a is formed at a position facing a pin hole 72a1 of the lock mechanism 70 that rotates around the head pipe 18 when the handlebars 21 are steered left or right.

[0042] As shown in FIG. 7, when the handle 21 is in a straight-ahead state, the rear edge 83 of the protection rib 80 overlaps with the main body 91 of the lock pin receiving portion 90 in a side view of the vehicle body. A connecting portion between the rear edge 83 and the lower edge 82, i.e., a lower portion forming an angular shape of the rear portion 80b of the protection rib 80 in a side view of the vehicle body, is provided above the base 92 of the lock pin receiving portion 90. In other words, the connecting portion between the rear edge 83 and the lower edge 82 is the lower end portion 80b1 of the rear portion 80b of the protection rib 80. The lower end portion 80b1 of the rear portion 80b is provided above the base 92 forming the lower end of the lock pin receiving portion 90 in a side view of the vehicle body. The pin engagement opening 91a is visible in a side view of the vehicle body.

[0043] FIG. 8 is a diagram showing the arrangement of cable-like members 101, 102, 103, and 104 around the head pipe 18. As shown in FIG. Around the head pipe 18, a switch cable (first cable-like member) 101 extending from the operating switch on the handlebar 21, a clutch cable (second cable-like member) 102 extending from the clutch lever, a wheel speed sensor cable (third cable-like member) 103 extending from the meter unit 44, a brake hose (fourth cable-like member) 104 extending from the reservoir tank, and the like are arranged.

[0044] The switch cable 101 extends from an operation switch provided on the left side of the handlebar 21. The switch cable 101 extends from the operation switch toward the headlight 41, and is connected to the headlight 41, the turn signal 45, and the like. The clutch cable 102 extends from the clutch lever on the left side of the handlebar 21 toward the center in the vehicle width direction, passes in front of the top bridge 52, and is routed below the top bridge 52. Below the top bridge 52, the clutch cable 102 passes between the top bridge 52 and the bottom bridge 53, and between the left fork member 51 and the lock mechanism 70, and is routed to the body frame 11 side.

[0045] The wheel speed sensor cable 103 extends downward from the meter unit 44, passes in front of the top bridge 52, and is routed below the top bridge 52. Below the top bridge 52, the wheel speed sensor cable 103 is routed between the top bridge 52 and the bottom bridge 53, passes between the left fork member 51 and the lock mechanism 70, and is routed rearward of the left fork member 51. The wheel speed sensor cable 103 is then routed downward along the left fork member 51 toward the front wheel 13.

[0046] The brake hose 104 extends from a reservoir tank provided on the right of the handlebar 21. The brake hose 104 extends from the reservoir tank toward the center in the vehicle width direction, passes in front of the top bridge 52, and is routed below the top bridge 52. Below the top bridge 52, the brake hose 104 passes between the top bridge 52 and the bottom bridge 53, and between the right fork member 51 and the lock mechanism 70, and is routed rearward of the right fork member 51. The brake hose 104 is then routed downward along the right fork member 51 toward the brake caliper of the front wheel 13.

[0047] Fig. 9 is a cross-sectional view of the periphery of the head pipe 18 when the handlebars 21 are in a straight-ahead state. Fig. 10 is a cross-sectional view of the periphery of the head pipe 18 when the handlebars 21 are steered to the right. Fig. 11 is a left side view of the periphery of the head pipe 18 when the handlebars 21 are in a straight-ahead state. Fig. 12 is a left side view of the periphery of the head pipe 18 when the handlebars 21 are steered to the right.

[0048] When the saddle-ride type vehicle 10 is stopped and the handlebars 21 are steered to the right, for example, the front forks 14 rotate integrally with the handlebars 21 about the stem pipe 54, and rotate from the state shown in Fig. 9 to the state shown in Fig. 10. Therefore, the headlight unit 60 and the lock mechanism 70 fixed to the front forks 14 also rotate about the stem pipe 54, and rotate integrally to the right around the head pipe 18.

[0049] At this time, when a key is inserted into the key cylinder portion 71 and turned to a predetermined position, in response to the key operation of the key cylinder portion 71, the lock pin 72b in the lock mechanism main body portion 72 protrudes from the pin hole 72a1 and fits into the pin engagement opening 91a provided in the head pipe 18. This restricts steering of the handlebars 21, thereby performing a so-called handlebar lock.

[0050] To release the handlebar lock, the key is inserted into the key cylinder 71 and turned, and in response to the key operation of the key cylinder 71, the lock pin 72b of the lock mechanism main body 72 retreats from the pin engagement opening 91a and sinks into the pin hole 72a1. This releases the handlebar lock, allowing the front fork 14 to be steered.

[0051] In this embodiment, a protective rib 80 is provided that can overlap with the lock pin 72b in a side view of the vehicle body. That is, when the lock pin 72b protrudes and moves to the locked position, the protective rib 80 covers the lock pin 72b from the side of the vehicle body, protecting the lock pin 72b from the outside of the vehicle body. Therefore, for example, even if a rod-shaped member is brought into contact with the lock pin 72b from the outside in the vehicle width direction, the protective rib 80 functions as an obstacle, making it difficult for the rod-shaped member to come into contact with the lock pin 72b. Therefore, unlocking of the lock pin 72b by means other than key operation is easily restricted, and theft is prevented.

[0052] Here, a clutch cable 102, a wheel speed sensor cable 103, a brake hose 104, etc. are arranged around the head pipe 18. These cable-like members 102-104 rotate left and right together with the front fork 14 when the handlebars 21 are steered. Therefore, for example, when the handlebars 21 are steered to the right, the clutch cable 102 and the wheel speed sensor cable 103 on the left side of the head pipe 18 move to the right and approach the lock mechanism 70. However, the side of the lock mechanism 70 is covered with the protective rib 80, and the clutch cable 102 etc. moving to the right come into contact with the protective rib 80 and are restricted in movement. In other words, the clutch cable 102 etc. are restricted from entering the lock mechanism 70.

[0053] In particular, the protective rib 80 has a curved lower edge 82. Here, the clutch cable 102 is connected to the clutch lever at its upper part, and the position of the upper part of the clutch cable 102 is unlikely to change relative to the lock mechanism 70. In contrast, the lower part of the clutch cable 102 is less constrained in order to absorb the change in distance that accompanies the rotation of the front fork 14 and the body frame 11. Therefore, the lower part of the clutch cable 102 is likely to move due to the operation of the handlebars 21. At this time, since the protective rib 80 of this embodiment has a curved lower edge 82, even if the lower part of the clutch cable 102 moves, it is likely to come into contact with the rounded lower edge 82 of the protective rib 80, and damage due to contact with the edge shape is prevented.

[0054] In addition, when the handlebars 21 are in a straight-ahead state, the rear edge portion 83 of the protective rib 80 overlaps with the main body portion 91 of the lock pin receiving portion 90 in a side view of the vehicle body, and the lower end portion 80b1 of the rear portion 80b of the protective rib 80 is provided above the base portion 92 of the lock pin receiving portion 90 in a side view of the vehicle body. For this reason, when the handlebars 21 are returned from a steering state to a straight-ahead state, the clutch cable 102 and the like extending from above are more likely to come into contact with the front portion 80a whose lower end is located below, and more likely to come into contact with the curved lower edge portion 82, than with the rear portion 80b (in other words, the rear edge portion 83) whose lower end portion 80b1 is located above. This makes it easier to protect the clutch cable 102 and the like. On the right side of the head pipe 18, the brake hose 104 extends in the vertical direction, but as the front fork 14 rotates to the right, it is easily pushed by the right-side protective rib 80 (see FIG. 10). Therefore, the brake hose 104 is restricted from entering the lock mechanism 70, etc.

[0055] As described above, according to this embodiment to which the present invention is applied, in a protective structure for a handlebar lock pin provided in a saddle-ride type vehicle 10 including a body frame 11 having a head pipe 18, a front fork 14 rotatably supported on the head pipe 18, a handlebar 21 that rotates integrally with the front fork 14, a headlight 41 supported on the front fork 14, and a lock mechanism 70 supported at the rear of the headlight 41 and provided so that a lock pin 72b can protrude toward the head pipe 18, the headlight 41 includes a headlight rear cover 63 that covers the main body of the headlight 41 from the rear in front of the head pipe 18, and the headlight rear cover 63 is integrally formed with a protective rib 80 that protrudes rearward from a position outer than the lock mechanism 70 in the vehicle width direction and covers the lock pin 72b of the lock mechanism 70 from the outer side in the vehicle width direction.

[0056] According to this configuration, the protection rib 80 provided on the headlight rear cover 63 protects the lock pin 72b, so that the lock pin 72b can be prevented from being broken or cut off, which contributes to theft prevention. In addition, since the protection rib 80 for theft prevention is provided integrally with the headlight rear cover 63, there is no need to provide a separate member for protecting the lock pin 72b, and the number of parts can be reduced. In addition, since the number of parts can be reduced, this contributes to cost reduction. Furthermore, since the protection rib 80 for the theft prevention is provided on the headlight rear cover 63 separated from the stem pipe 54, it is difficult to restrict the layout of the handlebars 21, and it is easy to provide freedom in the layout of the handlebars 21. Therefore, according to this configuration, the lock pin 72b can be protected while providing freedom in the layout of the handlebars 21 and reducing the number of parts.

[0057] In this embodiment, a pair of left and right protective ribs 80 are provided, and the lock mechanism 70 includes a key cylinder portion 71, which is disposed between the pair of left and right protective ribs 80. According to this configuration, the lock mechanism 70 can be protected from both the left and right sides.

[0058] In this embodiment, the protective rib 80 is formed so that the vertical width of the front portion 80a is greater than the vertical width of the rear portion 80b. According to this configuration, the protective rib 80 protects the lock pin 72b at the rear portion 80b to prevent theft, while the wide vertical width of the front portion 80a restricts movement of the clutch cable 102, etc., thereby protecting the clutch cable 102, etc., thereby making it easier to use the clutch cable 102, etc. for a long period of time.

[0059] In addition, in this embodiment, the protective rib 80 is formed so that, when viewed from the bottom, it has a curved shape that curves from the outer side in the vehicle body width direction toward the inner side in the vehicle body width direction, and also has a curved shape that curves downwardly convexly. According to this configuration, even if the clutch cable 102 etc. moves inward in the vehicle width direction and comes into contact with the protective rib 80 when steering the handlebars 21, no edge interference occurs with the clutch cable 102 etc., so damage to the clutch cable 102 etc. can be suppressed. This makes it easier to use the clutch cable 102 etc. for a long period of time.

[0060] In this embodiment, the lower end 80b1 of the rear portion 80b of the protection rib 80 is provided above the base portion 92 of the lock pin receiving portion 90 with which the lock pin 72b engages. According to this configuration, when the handlebars 21 are returned from a steering state to a straight driving state, the clutch cable 102 extending from above and the like are more likely to come into contact with the curved lower edge portion 82 than with the rear portion 80b whose lower end portion 80b1 is located at the upper side. This makes it easier to protect the clutch cable 102 and the like.

[0061] In this embodiment, the protective rib 80 is made of resin, and the lock pin receiving portion 90 is made of metal. According to this configuration, by using resin for some of the components of the lock mechanism 70, it is expected that material costs will be reduced and the vehicle will become lighter.

[0062] [Other embodiments] The above-described embodiment merely shows one aspect of the present invention, and any modification and application can be made without departing from the spirit and scope of the present invention.

[0063] In the above embodiment, a motorcycle having a front wheel 13 and a rear wheel 15 has been used as an example of saddle-ride vehicle 10, but the present invention is not limited to this, and the present invention can be applied to a three-wheel saddle-ride vehicle having two front or two rear wheels, or a saddle-ride vehicle having four or more wheels.
