  A handle bracket 25 as a handle fixing member is attached to the upper end portion of the steering shaft 6 described above. As shown in FIG. 3, the handle bracket 25 is fixed so as to sandwich the handle bar 24 from above and below, and the handle bar 24 and the handle bracket 25 can be rotated together with the steering shaft 6. The handle bracket 25 constitutes a steering member 26 for steering the front wheel 8 together with the central portion 24 </ b> A of the handle bar 24. One end side of an attachment piece 27 is attached to the handle bracket 25, and the other end side rises toward the meter unit 28 side. On the other hand, a metal connection piece 29 is extended from the meter unit 28 side, and the attachment piece 27 and the connection piece 29 are connected via a bolt B, whereby the entire meter unit 28 is attached. .

  The meter unit 28 is a unit in which instruments such as a speedometer 30, a fuel gauge 31, an odometer 32, and a warning light 33 such as an engine cooling water temperature are collectively incorporated in a meter casing 34. The meter casing 34 is formed of a synthetic resin material, and a main body portion 35 formed in a hollow box shape to accommodate the above-described instruments, and a lower edge portion of the main body portion 35 from the front wall surface 35A to both side surfaces. An extension portion 36 that extends downward in the form of a plate over a part of the auxiliary illumination lamp 37, which will be described later, is attached to the extension portion 36.

  The main body 35 has an outer casing 45 as shown in FIG. The outer casing 45 has a side wall surface along the entire circumference and is formed in a substantially rectangular tube shape that opens in both directions in the height direction. A support plate 38 is disposed inside the outer casing 45, and an indicator lamp 40 for illuminating the dial 39 of the instrument is supported on the inner surface side in addition to the instrument described above. The opening on the upper surface side of the outer casing 45 is covered with a transparent transmission plate 41 (instrument display surface). A frame wall 42 protrudes inward from the entire periphery of the transmission plate 41, and a leading edge thereof is abutted against the support plate 38 via a seal member 61. A fixing frame 43 is fitted between the transmission plate 41 and the upper end opening edge of the main body portion 35 to prevent the transmission plate 41 from coming off.

  A dial 60 is arranged inside the transmission plate 41 in parallel, and the driver can visually recognize the dial 60 through the transmission plate 41. The meter unit 28 is fixed to the handle bracket 25 in an inclined posture such that the transmission plate 41 is along the line-of-sight direction of the driver. On the other hand, the instrument is incorporated into the main body portion 35 or removed through an opening on the lower surface side of the outer casing 45, and the opening on the lower surface side is covered with a lower lid 44. A metal bracket having the connecting piece 29 is attached to the lower surface of the lower lid 44 along the same surface. Although not shown in detail, the lower bracket 44 is fastened together with the lower lid 44 to the outer casing 45 by screws. Yes.

  In the lower lid 44, a plurality of terminals from other instruments, including a terminal 46 from the speedometer 30, protrude in a substantially right half region of the meter unit 28 as viewed from the front of the vehicle. One end of a signal harness 47 as electrical wiring is connected to these terminals 46, and the other end is a measuring instrument (illustrated) attached to a measurement object (for example, a wheel when measuring vehicle speed) corresponding to each instrument. Not connected). A harness 48 for supplying power to each instrument (which may include signals) is drawn out from a substantially left half region of the lower lid 44.

  Both the front wall surface 35A and the left and right wall surfaces of the main body 35 are formed so as to be substantially orthogonal to the angle formed by the transmission plate 41 (instrument display surface 41A). In the outer casing 45, the outer surface of the right half region of the vehicle front view is formed so as to form a continuous arc surface from the front wall surface 35A to the right wall surface (left wall surface in FIG. 4), as shown in FIG. . The other side surface of the outer casing 45 is formed by a flat surface. However, in the front wall surface 35 </ b> A of the outer casing 45, the flat area is disposed at a position slightly rearward of the vehicle rearward than the circular arc area (see FIG. 3).

  A receding wall 49 is continuously formed on the front edge of the lower edge from the front wall surface 35A of the outer casing 45 to the left and right wall surfaces when viewed from the front of the vehicle, with a slope extending obliquely inwardly of the vehicle (rear of the vehicle if the front wall surface 35A). ing. The receding wall 49 is disposed below the front wall 35 </ b> A of the outer casing 45 and the left and right side walls crossing the plane formed by the lower lid 44 as a boundary. The lower edge portion of the receding wall 49 is further extended downward, that is, the extension portion 36 is extended downward from the space portion accommodating the instruments. In this embodiment, the extension portion 36 is formed over the entire width range on the front surface of the outer casing 45, and further, the left and right side surfaces are formed in a longitudinal direction as reinforcing portions 50 having a substantially triangular shape as shown in FIG. It extends to reach the center. Since the extension portion 36 is formed in a state of projecting downward from the lower lid 44, it also serves to protect the terminal 46 of the instrument and the lead-out portion of the power supply harness. A range corresponding to the width region in which the arc surface is formed on the front wall surface of the extension portion 36 is also formed in an arc shape with the same curvature. A portion of the extension portion 36 formed as an arc surface (referred to as an arc-like extension portion 36A) has a height-wise ridge line formed substantially parallel to a height-direction ridge line of the front wall surface 35A. However, the left half region of the extension portion 36 as viewed from the front of the vehicle forms a flat surface to form a flat extension portion 36B. An auxiliary illumination lamp 37, which will be described later, is attached to the planar extension 36B. The planar extension portion 36B is positioned rearward of the arc-shaped extension portion 36A, and the planar extension portion 36B is continuous with the receding wall 49 at an angle that is greater than the angle formed by the receding wall 49 itself. When the meter unit 28 is attached to the handle bracket 25, the surface is substantially along the vertical direction.

  A horizontally long and square window hole 51 is opened at the center of the planar extension 36B. An auxiliary illumination lamp 37 is assembled in the window hole 51. The auxiliary illumination lamp 37 includes a bulb unit 52, a holder 53 that accommodates the bulb unit 52, and a lens member 54.

  The holder 53 is hollow and integrally formed of a rubber material having cushioning properties. A frame portion 55 that is fitted into the window hole 51 is formed at the front end portion of the holder 53 so as to open in a substantially longitudinal direction of the vehicle. A locking groove 56 is formed in the outer peripheral edge of the frame portion 55 along the entire periphery. When the frame portion 55 is fitted into the window hole 51 while constricting and deforming, the frame portion 55 is prevented from coming off in the vehicle front-rear direction with respect to the window hole 51, and each groove wall of the locking groove 56 is formed in the window hole 51. It is possible to adhere to the edge of the hole with elasticity. A lens member 54 is fitted to the frame portion 55 from the front of the vehicle. The mounting height of the lens member 54 is set to be positioned slightly above the upper edge of the basket 23 as shown in FIG.

  The lens member 54 has a lens plate 54A formed with substantially the same size as the vehicle front end surface of the frame portion 55, and a rectangular tube-shaped latch that can be integrally fitted into the frame portion 55 by protruding integrally from the rear surface side of the lens plate 54A. It consists of a tube 54B. The locking cylinder 54B is formed to open rearward (opposite to the lens plate 54A), and a hooking claw 54C is formed on the outer periphery of the front end (rear end). The hooking claw 54 </ b> C is locked to a step 55 </ b> A formed at the opening edge in the frame portion 55, so that the entire lens member 54 is prevented from coming off. In a state where the lens member 54 is mounted, the outer peripheral surface of the locking cylinder 54B and the opening edge of the frame portion 55 are brought into close contact with an elastic force, and a sealing property between the locking cylinder 54B and the lens member 54A is ensured. By fitting the locking cylinder 54 </ b> B of the lens member 54 into the frame portion 55, the deformation of the frame portion 55 is restricted, and the prevention of the locking groove 56 from coming off from the opening edge of the window hole 51 is strengthened. . At the same time, the contact state between the groove edge of the locking groove 56 and the opening edge of the window hole 51 is strengthened, and the sealing performance between them is enhanced.

  As shown in FIG. 6, the back side of the frame portion 55 is hollow and integrally protruded with a pyramid-shaped constricted portion 57 constituted by four surfaces so that it gradually becomes constricted toward the rear. Is formed. The constricted portion 57 is continuous with a tubular valve housing portion 58 and extends rearward. A cylindrical portion 58 </ b> A that extends rearward along the lower surface of the lower lid 44 is formed on the upper side of the valve accommodating portion 58. Under the cylindrical portion 58A, a channel groove-shaped drainage portion 58B is formed along the length direction so as to protrude downward. The drainage part 58B is formed in communication with the cylindrical part 58A and is formed open to the rear end side.

  The cylindrical portion 58 </ b> A is also formed to open rearward and serves as an attachment port for the valve unit 52. The valve unit 52 includes a valve housing 52A made of synthetic resin and a valve 52B that can be attached to and detached from the valve housing 37A. The valve housing 52A is formed in a cylindrical shape having a bottom and an opening opposite to the bottom surface, and a flange edge 52C for preventing the slipping along the entire circumference at a rear end edge of the outer peripheral surface and a position spaced inward from the outer peripheral surface. Overhangs. Both flange edges 52C are pressed against each other so as to bite into the inner wall of the cylindrical portion 58A when the valve 52B is inserted into the cylindrical portion 58A with the valve housing 52A mounted. It has been retained. When the valve unit 52 is incorporated, the valve 37B is positioned behind the locking cylinder 54B in the lens member 54. As shown in FIG. 5, in the present embodiment, the axis of the valve 52B and the axis of the lens member 54 intersect each other. In addition, a pair of terminal fittings connected to the electric wire W are assembled inside the valve housing 52A and are in contact with the contacts of the valve 52B. The electric wire W drawn from the valve housing 52A is integrated with a power supply harness 48 drawn from the meter unit 28 side by tape winding.

  According to the present embodiment configured as described above, the auxiliary illuminating lamp 37 is assembled to the planar extension 36B formed by extending the front wall surface 35A of the main body 35 in which the instruments are incorporated downward. Therefore, it is not necessary to disassemble the main body portion 35 when the valve 52B needs to be replaced. The valve unit 52 can be removed from the holder 53 simply by pulling it strongly from the holder 53. Therefore, the replacement work of the valve 52B can be easily performed. In performing the replacement work, the back surface side of the planar extension 36B is a work space S that is open outward, that is, in the rear, side, and lower three directions, so that it is easy to put in the hand. The lamp 37 can be easily assembled and replaced. Since the back surface side of the planar extension portion 36B does not have a terminal that tends to be an obstacle to the operation unlike the back surface side of the arc-shaped extension portion 36A, the workability is further improved.

  By the planar extension 36B, the exit portion where the power supply harness 59 is drawn out from the main body portion 35, that is, the portion where the plurality of electric wires are not bundled neatly with tape or the like (the portion where the plurality of electric wires are exposed as they are) is covered. Therefore, it is effective for maintaining the appearance in front view of the vehicle. Further, since the terminal 46 for the instruments can be covered by the arc-shaped extension 36A, the terminal 46 can be protected when the meter unit 28 is in a single state, and the connection portion between the terminal 46 and the signal harness 47 can be provided. Since it can be covered by the vehicle front view, it contributes to maintaining the appearance.

  In the state where the meter unit 28 is fixed to the handle bracket 25, the planar extension 36B forms a substantially vertical surface, so that the auxiliary illumination lamp 37 can reliably illuminate the front of the vehicle. Since the auxiliary illumination lamp 37 is disposed at a position higher than the upper end edge of the basket 23, it is convenient for confirming the contents of the load (for example, a newspaper for delivery) in the basket 23. The basket 23 is attached to the vehicle body 12 that is fixed to the vehicle body frame 5, while the auxiliary illumination lamp 37 is attached to the steering member 26 that is movable to the vehicle body frame 5. By operating and changing the irradiation direction of the auxiliary illumination lamp 37, the illumination direction with respect to the load in the basket 23 can be arbitrarily changed. For this reason, it is possible to more easily check the content of the load.

  Since the planar extension part 36B in which the auxiliary illumination lamp 37 is arranged is arranged so as to be retracted backward with respect to the front wall surface 35A of the main body part 35 via the receding wall 49, it is an arrangement in which raindrops are not easily attached. Yes. Therefore, the chance of water immersion from the periphery of the lens member 54 can be reduced. For the same reason, rainwater adhering to the front wall surface 35A flows down the front wall surface 35A. However, due to its inertia, the rainwater falls downward from the lower edge of the front wall surface 35A, and travels along the receding wall 49 to the extension portion 36. It becomes difficult to be transmitted to the side. In the unlikely event that water enters the holder 53 from the periphery of the lens member 54, the water can remain outside the holder 53 for a long period of time because it can be drained to the outside through the drainage portion 58B. Things can be avoided.

From the above-described embodiment, the following technical idea can be grasped.
(1) A space opened outward is formed on the back side of the extension, and the auxiliary illumination lamp can be attached and detached through this open space.

With such a configuration, since the back side of the extension portion is opened outward as a work space, the work of attaching and removing the auxiliary illumination lamp can be easily performed.
(2) From the main body part, a harness for electrical connection with the instruments is drawn out and routed downward, while the extension part projects downward from the front surface of the main body part to cover the front of the harness. ing.

With such a configuration, the wiring for the instruments is covered by the extension portion, which can contribute to the improvement of the appearance of the motorcycle.
(3) A headlight is mounted on the front portion of the vehicle, and a luggage support portion is disposed above the headlight, and an auxiliary illumination lamp is positioned above the luggage support portion. With such a configuration, the headlight is not obstructed by the load support portion in any way, and the load in the load support portion is illuminated by the auxiliary lamp, so that the load can be easily confirmed.
(4) The motorcycle includes a vehicle body main body fixed to the vehicle body frame, a steering member that can rotate with respect to the vehicle body frame and supports the front wheels so that the front wheel can be steered, and the luggage support portion is fixed to the vehicle body frame. The auxiliary illumination lamp is arranged on a steering member on the movable side with respect to the vehicle body frame.

With such a configuration, by rotating the steering member, the irradiation direction of the illuminating lamp with respect to the load in the load supporting portion can be changed to a desired direction, so that confirmation of the load is further facilitated.
(5) The main body part is formed by intersecting the instrument display surface provided on the upper surface and the front wall surface at a right angle, and the extension part is arranged at the lower part of the front wall surface and the instrument display surface is inclined toward the driver. When the meter unit is assembled in the posture, the angle formed with the front wall surface is set so that the extension portion forms a vertical surface.

According to this configuration, the meter casing is formed so as to intersect the instrument display surface and the front wall surface at a right angle in a single state. When the meter unit is attached, the instrument display surface is inclined toward the driver, so if the extension is simply extended from the front wall surface, the extension will be inclined upward. According to the configuration, since the extension portion forms a vertical surface in the attached state of the meter unit, the auxiliary illumination lamp can reliably illuminate the front of the vehicle.
(6) A receding wall is continuously formed on the lower edge of the front wall surface of the main body portion toward the obliquely rearward side of the vehicle, and the extension portion is continuously formed on the lower edge of the receding wall.

If it is this structure, since the extension part was retreated with respect to the side wall surface of the main body part through an inclined surface having a rearward gradient called a retreating wall, rainwater adhering to the front wall surface of the main body part along the front wall surface Even if it flows down, rainwater can be easily dripped from the lower edge of the front wall surface, and the situation where the rainwater reaches the auxiliary illumination lamp through the extension can be alleviated.
(7) The auxiliary lighting lamp is connected to the terminal of the electric wiring, and a valve unit in which the valve can be detachably mounted, and a cushion that is detachably accommodated in the valve unit and that is assembled to the mounting opening formed in the extension portion. A holder made of a material, and a translucent lens member that is fitted to the front surface of the holder and closes the opening.

According to this configuration, each component of the auxiliary illumination lamp is assembled so as to be disassembled, so that an operation such as replacement can be easily performed.
(8) If a drainage part for drainage to the outside is formed in the holder, even if a situation occurs such that the lens member launches from the periphery of the lens member to the inside of the holder, Since it can drain from a drain part, the situation where water accumulates inside a holder can be avoided.

<Other embodiments>
(1) In this embodiment, the meter unit 28 having the auxiliary illumination lamp 37 is assembled to the steering member 26, but it may be incorporated into the vehicle body 12.

  (2) Although the extension part 36 of the present embodiment is formed by extending downward from the main body part 35, the extension direction is not limited to the downward direction, and may be an upward direction or a horizontal direction (vehicle width direction). .

  (3) In the present embodiment, the auxiliary illumination lamp 37 is disposed on the planar extension 36B, but may be disposed on the arc-shaped extension 36A.

  (4) The extension portion does not need to be integrally extended from the main body portion, and may be extended using a member separate from the main body portion.
