Description

  FIG. 1 shows an entire side surface of a tractor that is an example of a work machine, and this tractor is a riding-type traveling in which a riding operation unit 3 is formed between a pair of left and right front wheels 1 and a rear wheel 2. At the rear part of the machine body 4, a link mechanism 5 for connecting the work device is provided so as to be able to be driven up and down.

  The boarding driving unit 3 includes a steering wheel 6 linked to the left and right front wheels 1, a driver seat 7 arranged between the left and right rear wheels 2, and a boarding step arranged between the front wheels 1 and the rear wheels 2. 8, etc. are formed.

  An engine room is formed in the front part of the traveling machine body 4 by a pair of left and right side panels 11 having an intake front grill 9, an exhaust side grill 10, and an openable bonnet 12. An engine 13 and a radiator 14 are disposed in the room.

  As shown in FIGS. 1 to 11, a headlamp 15 is mounted on the upper portion of the front grille 9, and the headlamp 15 is attached to a single body 16 made of a molded product made of ASA resin with PP resin. The left and right reflectors 17 made of a molded product and a single lens 18 made of an acrylic resin molded product are provided.

  The body 16 is substantially U-shaped in plan view having a center portion 19 facing forward and left and right end portions 20 extending rearward, and an opening 21 for attaching the reflector 17 to the left and right of the center portion 19. Is formed. An engaging edge 22 that engages with the reflector 17 and an engaging claw 23 that engages with the reflector 17 are formed on the periphery of each opening 21. A flange portion 24 for connection to the front grill 9 extends from the lower edge of the center portion 19 and the left and right end portions 20 of the body 16 toward the inside of the machine body, and these flange portions 24 are formed in the front grill 9. To be bolted.

  Each of the left and right reflectors 17 has a substantially bowl shape in which a valve mounting portion 26 for detachably mounting a main valve 25 for front irradiation from the rear is formed at the center thereof, and the surface thereof is subjected to aluminum vapor deposition treatment. A reflection surface 27 is formed that reflects light from the main bulb 25 forward. The reflection surface 27 is formed in a polyhedral shape having a plurality of reflection elements 28 for obtaining a predetermined light collection / distribution pattern. At the front edge of each reflector 17, an engagement groove 29 that engages with the engagement edge 22 of the body 16 and a locked portion 30 that is locked to the locking claw 23 of the body 16 are formed.

  Each reflector 17 is attached to the body 16 by engaging the engaging edge 22 of the body 16 with the engaging groove 29 of the reflector 17 in a state where the engaging groove 29 of the reflector 17 is filled with the adhesive 31. This can be done by locking the locking claw 23 of the body 16 to the locked portion 30.

  That is, since the left and right reflectors 17 are independently formed as described above, the left and right reflectors 17 are made up of a plurality of reflecting elements 28 as compared with the case where the left and right reflectors 17 are integrally formed with the body 16. It is easy to form into a multi-faceted shape, and aluminum vapor deposition that can improve the light reflection performance and give a high-class feeling compared to the case where the reflective surface 27 is formed by painting or plating. The left and right reflectors 17 can be applied only to the reflectors 17 without the need for labor and cost of masking the portions other than the reflector forming portions, which are required when the reflectors 17 are integrally formed with the body 16. While simplifying the configuration and reducing the manufacturing cost, it is possible to form a reflector 17 with high light reflection performance and high quality. You have me.

  The lens 18 faces the corresponding reflector 17, the left and right lens portions 32 that transmit light from the corresponding main bulb 25 and the reflector 17 forward, and the front wall portion 33 that extends between the inner ends of the lens portions 32. Further, it is formed in a U-shape in a plan view having a side wall portion 34 bent from the outer ends of the left and right lens portions 32 and extending rearward.

  Each of the left and right lens portions 32 is formed as a clear lens that has not been subjected to lens cutting for forming a lens element for light collection / distribution, so that the lens 18 can be molded easily and inexpensively. It has become. On the back surface of the front wall portion 33, a plurality of left and right ribs 35 bulging rearward are formed in parallel in the vertical direction, whereby reinforcement at the front wall portion 33 of the lens 18 can be achieved, The occurrence of warpage at the front wall portion 33 can be prevented. On the back surface of the bent portion of each of the left and right side wall portions 34, a plurality of left and right ribs 36 that bulge rearward are formed in parallel in the vertical direction. In addition to being able to reinforce, it is possible to prevent the springback of the lens 18 formed in a U-shape in plan view.

  Engagement edges 37 that engage the body 16 and locking claws 38 that lock the body 16 are formed on the periphery of the lens 18. A concave portion 39 for attaching the lens 18 is formed on the surface of the body 16, and an engaging groove 40 that engages an engaging edge 37 of the lens 18 and a locking claw of the lens 18 are formed on the periphery of the concave portion 39. The to-be-latched part 41 latched by 38 is formed.

  The lens 18 is attached to the body 16 by engaging the engagement edge 37 of the lens 18 with the engagement groove 40 of the body 16 in a state where the engagement groove 40 of the body 16 is filled with the adhesive 31. This can be done by locking the locking claw 38 of the lens 18 to the locked portion 41. With this attachment, the lens 18 is joined and mounted to the concave portion 39 of the body 16 so as to cover both the left and right reflectors 17 from the front.

  That is, the lens 18 is configured by a single U-shaped single member that covers both the left and right reflectors 17 from the front, and is divided by a pair of left and right members that cover the left and right corresponding reflectors 17 from the front. Compared to the case, the U-shaped lens 18 in the plan view is left and right of the substantially U-shaped body 16 in the plan view while facilitating the parts management, the simplification of the configuration, and the reduction of the manufacturing cost. By joining the two reflectors 17 so as to cover the front from the front, the shape of the body 16 is complicated, or a new reinforcing member is not added to the body 16, so that the entire body 16 can be made. The lens 18 can be reinforced, so that high strength can be secured as the headlamp 15 without causing an increase in manufacturing cost and a complicated configuration. It has become way.

  Further, as described above, the left and right reflectors 17 are independently formed. Therefore, by combining the reflectors 17 with the bodies 16 and the lenses 18 having different shapes, the reflectors 17 can be used as the headlamp 15 while using the reflectors 17 as common parts. Therefore, the headlamp 15 can be made versatile without causing an increase in manufacturing cost.

  The lens 18 is formed such that the vertical width L1 of the front wall portion 33 is narrower than the vertical width L2 of the left and right lens portions 32. On the other hand, in the body 16, the vertical widths L 3 and L 4 of the upper and lower edge portions 42 and 43 with respect to the front wall portion 33 of the lens 18 are wider than the vertical widths L 5 and L 6 of the upper and lower edge portions 44 and 45 with respect to the lens portion 32. It is formed as follows. As a result, the shape of the body 16 and the lens 18 can be changed as compared with the case where the vertical widths of the body 16 and the lens 18 are made constant, and the appearance can be improved. The section modulus of each of the upper and lower edge portions 42 and 43 in the left and right central portions can be increased, and the strength of the body 16 itself can be increased.

  The headlamp 15 is turned on and off by a switch (not shown) installed in the boarding operation unit 3.
