The driver visually confirms the meter unit 44 through the opening 62a. A circular lock hole 62b penetrating in the up-down direction is formed behind the opening 62a. The lock holes 62b are formed in the left and right central portions of the front upper cover 62.

A lock mechanism (handle lock mechanism) 70 is disposed below the lock hole 62 b. The locking mechanism 70 is secured to the header 52. The lock mechanism 70 is disposed forward of the front riser 18.

The lock mechanism 70 includes a cylindrical lock cylinder portion 71 extending in the up-down direction, and a lock mechanism main body portion 72 provided below the lock cylinder portion 71 and having a larger diameter than the lock cylinder portion 71.

A sheet-like support plate 73 protruding rearward is formed between the lock core portion 71 and the lock mechanism main body portion 72. The support plate 73 is formed with a pair of left and right sides across the key cylinder 71. The bolts 73a are inserted into the support plate portions 73 from below. Bolts 73a are fastened to the lower surface of the header 52. Thus, the lock mechanism 70 can rotate integrally with the front fork 14 on the front side of the front standpipe 18. The lock mechanism 70 is disposed at the vehicle width direction center portion. The lock mechanism 70 rotates on the front outer peripheral side of the front riser 18.

A key insertion portion 71a is formed at an upper portion of the key cylinder portion 71. The key insertion portion 71a is attached to the lock hole 62b of the front upper cover 62 from below. A key (not shown) is inserted into the key insertion portion 71a from above.

A rear surface 72a facing the front pillar 18 is formed at a vehicle width direction center portion of the lock mechanism main body portion 72 of the lock mechanism 70. The rear surface 72a is a flat surface. A pin hole 72a1 extending from the front of the rear surface 72a to the rear is formed in the rear surface 72a. The pin hole 72a1 is formed in the left and right central portions. The lock pin 72b (see fig. 4) is slidably supported by the pin hole 72a1. The lock pin 72b is interlocked with the operation of the key inserted in the key cylinder portion 71. The lock pin 72b is configured to be movable between a lock position protruding rearward from the pin hole 72a1 and a lock release position buried in the pin hole 72a1.

The cable 74 extends from below the lock mechanism main body 72. The cable 74 extends downward, then is routed rightward, and is routed inside the front cover 31. The cable 74 is connected to the key cylinder portion 71.

As shown in fig. 5, roof beam fixing portions 63a are formed on the left and right sides of the lock mechanism 70 on the headlamp rear housing 63. The roof rail fixing portion 63a is fixed to the rear roof rail 52 by bolts 63b extending from the front.

A pair of left and right bottom beam fixing portions 63c are formed at the lower end portion of the headlamp rear housing 63. The bottom beam fixing portion 63c is fixed to the bottom beam 53 by bolts 63d extending rearward from the front.

The top beam fixing portion 63a and the bottom beam fixing portion 63c of the present embodiment are disposed between the pair of fork members 51. The head lamp unit 60 is integrated with the front fork 14 by the roof rail fixing portion 63a and the floor rail fixing portion 63 c. The headlight unit 60 is supported so as to be rotatable integrally with the front fork 14.

Protective ribs (pin protective ribs) 80 protruding rearward are formed below the roof rail fixing portion 63a on both left and right sides of the lock mechanism 70. The protection rib 80 is integrally formed at the rear surface of the headlamp rear cover 63. Therefore, the protective rib 80 is formed of resin similarly to the headlamp rear cover 63. The protection rib 80 is formed corresponding to the left and right of the lock mechanism 70. Therefore, the lock core portion 71 and the lock mechanism main body portion 72 of the lock mechanism 70 are located between the left-side protection rib 80 and the right-side protection rib 80. The protection rib 80 is a curved plate shape protruding rearward. In the present embodiment, the protection rib 80 is formed at the same height as the pin hole 72a1 of the lock mechanism main body 72. The protection rib 80 overlaps the rear surface 72a of the lock mechanism main body 72 in a side view of the vehicle body (see fig. 3). The protection rib 80 overlaps the lock pin 72b protruding from the rear surface 72a when the vehicle body is viewed from a side. In the present embodiment, the locking pin 72b overlaps the front portion thereof.

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 81 extends rearward and downward from the rear surface of the headlamp rear cover 63 in a side view of the vehicle body. The lower edge 82 extends rearward and upward from a position lower than the upper edge 81 in a side view of the vehicle body. A 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 trailing edge portion 83 extends in the up-down direction. The trailing edge 83 is inclined along the inclination of the front riser 18. The upper edge 81 of the protective rib 80 is formed at a portion thereof in the front-rear direction, and the vertical width thereof decreases as the protective rib advances rearward. The upper-lower width of the rear portion (vehicle body front-rear direction rear portion) 80b is narrower than the upper-lower width of the front portion (vehicle body front-rear direction front portion) 80a of the protection rib 80.

The lower edge 82 of the protective rib 80 is curved inward in the vehicle width direction as it proceeds downward. The lower edge 82 is convexly curved outward in the vehicle width direction. The lower edge 82 is curved from the vehicle width direction outside to the vehicle width direction inside when viewed from the bottom. Therefore, when the clutch cable 102 moves from the vehicle width direction outside and comes into contact with the periphery of the lower edge 82 of the protective rib 80 during the operation of the front fork 14, the contact surface of the protective rib 80 is formed in a rounded curved surface shape, so that the protective rib 80 is unlikely to damage the clutch cable 102, and the clutch cable 102 is easy to use for a long period of time.

Fig. 7 is a left side view showing the periphery of the header 52.

A lock pin receiving portion 90 is formed at an upper end portion of the front riser 18. The lock pin receiving portion 90 is made of metal. The lock pin receiving portion 90 includes a semi-cylindrical main body 91 having a diameter larger than the outer diameter of the front riser 18, and a base 92 formed at the lower end of the main body 91 and connected to the front riser 18. The base 92 is fixed to the outer peripheral portion of the front riser 18. The base 92 is fixed obliquely in a direction orthogonal to the oblique direction of the front riser 18. In the present embodiment, the base 92 constitutes the lower end of the lock pin receiving portion 90. A pair of pin engagement openings 91a are formed in the left and right of the main body 91. The pin engagement opening 91a is formed to have an opening width of such a size that the lock pin 72b can be inserted. In the present embodiment, the pin engagement opening 91a is formed by cutting a substantially U-shape downward from the upper end of the main body 91. The pin engagement opening 91a is formed at a position facing the pin hole 72a1 of the lock mechanism 70 that rotates about the front pillar 18 when the handle 21 is turned left and right.

As shown in fig. 7, when the handle 21 is in the straight-running state, the rear edge 83 of the protection rib 80 overlaps the main body 91 of the lock pin receiving portion 90 when the vehicle body is viewed from the side. The connection portion between the rear edge 83 and the lower edge 82, that is, the lower portion of the rear portion 80b of the protective rib 80, which is formed in an angular shape in a side view of the vehicle body, is disposed above the base 92 of the lock pin receiving portion 90. In other words, the connection portion of the rear edge portion 83 and the lower edge portion 82 is the lower end portion 80b1 of the rear portion 80b of the protection rib 80. The lower end 80b1 of the rear portion 80b is provided above the base 92 constituting the lower end of the lock pin receiving portion 90 in a side view of the vehicle body. The pin engagement opening 91a can be visually confirmed when the vehicle body is viewed from a side view.

Fig. 8 is a diagram showing a wiring state of the cable-like members 101, 102, 103, 104 around the front riser 18.

At the periphery of the front riser 18 are arranged: a switch cable (first cable-like member) 101 extending from the operation switch of the handle 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 pipe (fourth cable-like member) 104 extending from the reservoir tank, and the like.

The switch cable 101 extends from an operation switch provided at the left portion of the handle 21. The switch cable 101 extends from the operation switch to the headlight 41, and is connected to the headlight 41, the direction indicator lamp 45, and the like.

The clutch cable 102 extends from the clutch lever at the left part of the handle 21 toward the vehicle width direction center part, passes through the front of the roof rail 52, and is disposed below the roof rail 52. The clutch cable 102 is routed below the top beam 52, between the top beam 52 and the bottom beam 53, and between the left fork member 51 and the lock mechanism 70, and on the frame 11 side.

The wheel speed sensor cable 103 extends downward from the meter unit 44, passes in front of the roof rail 52, and is routed below the roof rail 52. The wheel speed sensor cable 103 is disposed below the top beam 52, between the top beam 52 and the bottom beam 53, and between the left fork member 51 and the lock mechanism 70, and is disposed at a position rearward of the left fork member 51. The wheel speed sensor cable 103 is routed downward along the left fork member 51 and toward the front wheel 13.

The brake pipe 104 extends from a reservoir tank provided at the right portion of the handle 21. The brake pipe 104 extends from the reservoir tank toward the vehicle width direction center portion, passes through the front of the roof rail 52, and is disposed below the roof rail 52. The brake pipe 104 is disposed below the top beam 52, between the top beam 52 and the bottom beam 53, and between the right fork member 51 and the lock mechanism 70, and further rearward than the right fork member 51. The brake pipe 104 is routed downward along the right fork member 51 and toward the brake caliper of the front wheel 13.

Fig. 9 is a cross-sectional view of the periphery of the front riser 18 in the case where the handle 21 is in a straight-running state. Fig. 10 is a cross-sectional view of the periphery of the front riser 18 in the case where the handle 21 is turned to the right. Fig. 11 is a left side view of the periphery of the front riser 18 in the case where the handle 21 is in a straight-ahead state. Fig. 12 is a left side view of the periphery of the front riser 18 with the handle 21 turned to the right.

When the saddle type vehicle 10 is parked and the handle 21 is turned to the right, for example, the front fork 14 rotates integrally with the handle 21 about the pillar 54, and rotates from the state shown in fig. 9 to the state shown in fig. 10. Accordingly, the head lamp unit 60 and the lock mechanism 70 fixed to the front fork 14 also rotate around the pillar 54 as a center, and integrally rotate rightward around the front pillar 18.

At this time, when the key is inserted into the lock core portion 71 and turned to a predetermined position, the lock pin 72b protrudes from the pin hole 72a1 in the lock mechanism main body portion 72, and is fitted into the pin engagement opening 91a provided in the front pillar 18 in conjunction with the key operation of the key cylinder portion 71. Thereby, the steering of the handle 21 is restricted, and so-called handle lock is performed.

When the handle lock is released, the lock pin 72b is retracted from the pin engagement opening 91a in the lock mechanism main body 72 and buried in the pin hole 72a1 in conjunction with the key operation of the lock core 71 when the key is inserted into the lock core 71 and rotated. This releases the handle lock, and enables steering of the front fork 14.

In the present embodiment, a protection rib 80 is provided so as to overlap the lock pin 72b when the vehicle body is viewed from the side. That is, when the lock pin 72b protrudes and moves to the lock position, the protection rib 80 covers the lock pin 72b from the vehicle body side surface and protects the lock pin 72b from the vehicle body outside. Therefore, for example, even if the bar-shaped member is to be brought into contact with the lock pin 72b from the vehicle width direction outer side, the protection rib 80 functions as an obstacle, and the bar-shaped member can be made difficult to be brought into contact with the lock pin 72b. Therefore, the lock release of the lock pin 72b other than the key operation is easily restricted, and theft is prevented.

Here, a clutch cable 102, a wheel speed sensor cable 103, a brake pipe 104, and the like are disposed around the front riser 18. These cable-like members 102 to 104 are rotated left and right together with the front fork 14 by the steering of the handle 21. Therefore, for example, when the handle 21 is turned to the right, the clutch cable 102 and the wheel speed sensor cable 103 located on the left side of the front vertical tube 18 move to the right side and approach the lock mechanism 70. However, the side portion of the lock mechanism 70 is covered with the protective rib 80, and the movement of the clutch cable 102 or the like moving to the right side is restricted by contact with the protective rib 80. That is, the clutch cable 102 or the like is restricted from entering the lock mechanism 70.

In particular, the lower edge 82 of the protective rib 80 has a curved shape. Here, the clutch cable 102 is connected to the clutch lever at the upper side, and the position of the upper portion of the clutch cable 102 with respect to the lock mechanism 70 is hardly changed. In contrast, the lower side of the clutch cable 102 is less restricted in order to absorb the distance change accompanying the rotation of the front fork 14 and the frame 11. Therefore, the lower portion of the clutch cable 102 is easily moved by the operation of the handle 21. At this time, since the lower edge 82 of the protection rib 80 of the present embodiment has a curved shape, even if the lower portion of the clutch cable 102 moves, the lower edge 82 with roundness of the protection rib 80 is easily contacted, and damage due to contact with the edge shape is prevented.

When the handle 21 is in the straight-running state, the rear edge 83 of the protection rib 80 overlaps the main body 91 of the lock pin receiving portion 90 in a side view of the vehicle body, and the lower end 80b1 of the rear portion 80b of the protection rib 80 is disposed above the base 92 of the lock pin receiving portion 90 in a side view of the vehicle body. Therefore, when the handle 21 is returned from the steering state to the straight state, the clutch cable 102 or the like extending from above is more likely to contact the front portion 80a having the lower end located below and is more likely to contact the curved lower edge 82 than the rear portion 80b (in other words, the rear edge 83) having the lower end 80b1 located above. Therefore, the clutch cable 102 and the like are easily protected.

Further, on the right side of the front standpipe 18, the brake pipe 104 extends in the up-down direction, but is easily pushed by the right side protection rib 80 as the front fork 14 rotates rightward (see fig. 10). Thus, the brake pipe 104 is restricted from entering the locking mechanism 70 or the like.
