In addition, a meter visor 15b that shields light from the front is erected on the front side of the meter unit 16.

  Container portions 10a and 10b are formed on the left and right sides of the leg shield 10, respectively. Each of the container parts 10a and 10b is configured such that a part of the leg shield 10 is bulged forward to form a box part, and the opening of the box part is opened and closed by lids 17 and 18.

  A mounting seat 10c recessed in the front of the vehicle is formed on the right side of the vehicle center between the left and right container portions 10a and 10b. A main switch device 20 is disposed on the mounting seat 10c.

  The main switch device 20 is configured by integrally connecting an immobilizer unit 21 and a main switch unit 22 that prevent theft and mischief. The main switch device 20 is bolted and fixed to the vehicle body frame via a bracket portion 21 a formed in the immobilizer unit 21.

  The main switch unit 22 mounts and fixes a key cylinder 25 in a cylinder case portion 23a formed in the unit case 23, and electrically connects the key cylinder 25 to a concave box portion 23b formed in the unit case 23. The connected wiring cable 26 is clamped.

  The key cylinder 25 includes a cylinder body 28 that supports a cylindrical key insertion portion 27 having a key insertion hole 27a so as to be rotatable between ON-OFF-LOCK-P. By inserting the key 29 into the key insertion hole 27a and turning it, the ignition device is turned on / off and the handle lock device is locked / unlocked.

  An upper end portion of the cylinder case portion 23a protrudes from the mounting seat 10c of the leg shield 10 toward the rear of the vehicle, and an uneven pattern is formed on the outer peripheral surface of the protruding portion by embossing.

  A circular opening 23d is formed in the protruding end surface 23c of the cylinder case 23a, and a tongue piece 23e that is curved in an R shape toward the center in a cross-sectional view is formed annularly on the periphery of the opening 23d. Yes. The upper end surface of the cylinder main body 28 is in contact with the tongue piece 23e, whereby the key insertion hole 27a is recessed from the upper end surface 23c of the cylinder case 23a toward the front of the vehicle. A seal ring 30 is interposed between the cylinder body 28 and the tongue piece 23e.

  The key insertion surface 27a 'in which the key insertion hole 27a of the key insertion portion 27 is formed is formed to be flush with the key insertion hole 27a. The protruding end surface 23c, which is an outer surface located outside the key insertion surface 27a ', is formed in parallel with the key insertion surface 27a', and the key insertion surface 27a 'and the outer surface (projecting end surface) 23c are connected to each other. The tongue piece 23e as a connecting surface is formed in the R shape.

  An annular seat groove 23f is formed in the outer peripheral portion of the outer surface 23c located outside the connecting surface 23e of the cylinder case portion 23a so as to surround the key insertion hole 27a. The formed phosphorescent sheet 33 is disposed so as to be flush with the outer surface 23c.

  The phosphorescent sheet 33 is non-rotatably positioned by engaging a notch recess (positioning engagement portion) 33a formed in the light storage sheet 33 with an engagement portion 23g formed in the sheet groove 23f. By engaging the notch recess 33a of the phosphorescent sheet 33 with the engaging portion 23g, the operation position of the key insertion portion 27 and the characters on the phosphorescent sheet 33 can be easily aligned.

  The phosphorescent sheet 33 is a protective layer made of a transparent resin having a hardness of a predetermined value or more, that is, a hardness that does not cause scratches that are visible to the naked eye even when the key 29 is abutted when the key 29 is inserted. 34, a printed layer 35 disposed on the back surface of the protective layer 34 and printed with characters such as the above-mentioned ON-OFF-LOCK-P and symbols such as arrows, and a phosphorescent disposed on the back surface of the printed layer 35 The layer 36 and the ultraviolet blocking layer 37 disposed on the surface of the protective layer 34 are provided, and these layers are laminated and fixed. Furthermore, an adhesive layer 38 is disposed on the back surface of the phosphorescent layer 36, and the phosphorescent sheet 33 is detachably adhered and fixed in the sheet groove 23f by the adhesive layer 38.

  As shown in FIG. 1A, the phosphorescent sheet 33 is formed by laminating the ultraviolet blocking layer 37, the protective layer 34, and the printing layer 35 in this order from the surface side, and applying a phosphorescent coating on the printing layer 35. The phosphorescent layer 36 is formed, and the adhesive layer 38 is laminated on the phosphorescent layer 36. In addition, in manufacture of the said luminous sheet | seat 33, it will be reversed and it will manufacture by putting the ultraviolet shielding layer 37 of the surface side below.

  Here, in the case of the manufacturing method described above, the phosphorescent layer 36 is formed by entering a part of the phosphorescent paint so as to fill between the characters of the printed layer 35, and the entered portion 36a. Fulfills its original function. Accordingly, the portion 36b located on the back side of the characters or the like of the phosphorescent layer 36 may be thin, and the required amount of phosphorescent paint can be reduced accordingly.

  The protective layer 34 is composed of, for example, a PET laminate layer made of polyethylene resin, urethane resin, polycarbonate resin, acrylic resin, polypropylene resin, or the like. By forming this protective layer 34 with a PET laminate layer, it is possible to increase transparency and strength, and to reliably prevent scratching during key insertion. Moreover, the said ultraviolet shielding layer 37 is comprised with the compound which has a function which cuts the ultraviolet-ray of sunlight.

  The phosphorescent layer 36 includes a phosphorescent pigment and a binder, and has a function of absorbing and storing sunlight, electric light, and the like and emitting the stored light. The phosphorescent layer 36 is made of, for example, a phosphor composed mainly of an alkaline earth metal sulfide and zinc sulfide, and a trace amount of heavy metal added thereto. Here, by adding a radioactive element such as radium, it is possible to enhance the phosphorescence performance, which makes it possible to emit light for a long time in the dark.

  9 and 10 are diagrams showing the results of tests performed to confirm the effect of this embodiment. In this test, we prepared a phosphorescent sheet with a printed layer and a phosphorescent layer on the back side of the protective layer and an ultraviolet blocking layer on the surface, and irradiated the ultraviolet ray for a long time to examine the discolored state of the printed layer. (See FIGS. 9A and 9B). For comparison, the same discoloration state was examined for a phosphorescent sheet not provided with an ultraviolet blocking layer (see FIGS. 10A and 10B).

  As shown in FIG. 10B, in the phosphorescent sheet prepared for comparison, the character portion is discolored due to sunburn. In particular, the discoloration of the character portion indicated as IGNION and ON was remarkable. On the other hand, in the case of the phosphorescent sheet of this embodiment, no discoloration has occurred over the entire character portion.

  As described above, according to the present embodiment, the phosphorescent sheet 33 is formed by sequentially arranging the printed layer 35 and the phosphorescent layer 36 on which characters and symbols such as ON-OFF-LOCK are printed on the back surface of the protective layer 34 made of PET laminate. Since the ultraviolet blocking layer 37 is arranged on the surface of the protective layer 34, the ultraviolet rays of sunlight hardly reach the print layer 35 and the phosphorescent layer 36, and when the vehicle body is used outdoors for a long time. Further, discoloration due to sunburn can be prevented, and deterioration of the phosphorescent layer 36 can be suppressed.

  In addition, since the protective layer 34 is made of a PET laminate resin having a hardness of a predetermined value or more, even if the key 29 hits the phosphorescent sheet 33 when the key is inserted, the protective layer 34 and the phosphorescent layer 36 can be prevented from being damaged. Deterioration of appearance can be prevented.

  Furthermore, since the adhesive layer 38 is disposed on the back surface of the phosphorescent layer 36, the phosphorescent sheet 33 can be securely attached by a simple operation of simply sticking the adhesive layer 38 to the sheet groove 23f of the cylinder case portion 23a. Further, the phosphorescent sheet 33 can be replaced due to damage or deterioration.

  In the present embodiment, since the phosphorescent sheet 33 is disposed on the outer surface 23c outside the connecting surface 23e of the key cylinder 25, the phosphorescent sheet 33 is removed from the key insertion hole 27a while ensuring the visibility of the key insertion hole 27a. It can arrange | position in the distant position, it can avoid that the key 29 hits the phosphorescence sheet 33, and the damage to the phosphorescence sheet 33 can also be prevented from this point.

  Since the phosphorescent sheet 33 is formed in an annular shape so as to surround the entire outer periphery of the key insertion hole 27a, the key insertion position can be easily recognized even in the dark.

  Further, the phosphorescent sheet 33 is formed by laminating a protective layer 34 and a printing layer 35 in order from the ultraviolet blocking layer 37 on the surface side, forming a phosphorescent layer 36 by applying a phosphorescent paint thereon, and further laminating an adhesive layer 38. Since it is manufactured, the amount of accumulated light necessary for manufacturing can be minimized, and the cost can be reduced.

  In the above embodiment, the case where the phosphorescent sheets 33 are sequentially laminated from the front surface side is described. However, in the present invention, the phosphorescent sheets 33 may be sequentially laminated from the back surface side. In this case, as shown in FIG. 1B, the phosphorescent layer 36 is formed by laminating a thin phosphorescent film on the adhesive layer 38. In the case of this manufacturing method, the phosphorescent layer 36 can be formed in a separate process, and the cost can be reduced.

  Moreover, although the said embodiment demonstrated the case where the luminous sheet | seat 33 was formed in cyclic | annular form, the luminous sheet | seat of this invention is not restricted to this shape, Various modifications can be considered. For example, as shown in FIG. 11A, an arrow-shaped protrusion 33b may be formed at a position corresponding to either ON or OFF of the annular phosphorescent sheet 33.
