FIG. 7 is a front sectional view of the left fender cover showing a state in which the buckle is housed. FIG. 8 is a perspective view of the main part showing the installation state of the right fender cover, FIG. 9 is a perspective view of the main part showing a state in which the tongue is housed, and FIG. 10 is a front sectional view of the right fender cover. FIG. 11 is a front sectional view of the right fender cover showing a state in which the tongue is housed.

  As shown in FIGS. 4 to 11, the left and right fender covers 23 </ b> L and 23 </ b> R are located at the base end side of the safety frame 18 so as to surround the periphery of the base end of the safety frame 18. A portion 36 is formed. A frame insertion portion 37 through which the base end portion of the safety frame 18 is vertically inserted is formed on the center side of the upper surface of the cover portion 36, and the seat 13 side (right and left inner side) of the cover portion 36 is An inclined surface 38 that is inclined downward from the upper surface of the cover portion 36 toward the seat 13 (inner side) is formed.

  The fender cover 23 includes an auxiliary cover portion 39 that extends integrally from the cover portion 36 to the rear side. As described above, the auxiliary cover portion 39 extends further rearward than the fender 19 and can prevent the muddy water and the like in the field from splashing up to the cover portion 36 side by the rear wheel 2 and the like.

  Further, an assist bar side fixing portion 41 is formed at the front end portion of the fender cover 23, and the rear portion of the inclined surface 38 of the fender cover 23 has a reverse U-shape in a side view, and the control portion side frame. A steering portion side fixing portion 42 protruding to the 17 side is formed. Then, the assist bar side fixing portion 41 is bolted to the fender 19 side together with the rear end portion of the side operation panel 22 and the rear end portion of the assist bar 21 by fastening together, and the control portion side fixing portion 42 is fixed to the control portion. The fender cover 23 is attached and fixed to the traveling machine body 7 side without a backlash by, for example, fixing the bolt to the control unit side frame 17 in a state of being placed so as to cover the upper end of the side frame 17.

Next, the structure of the buckle holding part and the tongue holding part provided in the fender cover will be described with reference to FIGS.
The buckle holding portion 31 is integrally formed with the front half of the inclined surface 38 of the fender cover 23L, while the tongue holding portion 32 is integrally formed with the front half of the inclined surface 38 of the fender cover 23R. .

  As shown in FIGS. 4 to 7, the above-described buckle holding portion 31 is formed in a planar view rectangular frame shape with the top and bottom open, and an insertion portion 44 through which the buckle 43 is vertically inserted is formed. ing. Thus, the front-rear direction center part of the seat 13 side wall part (around the buckle holding part 31) of the buckle holding part 31 formed in a cylindrical shape in the vertical direction is opened in a slit shape over the entire vertical direction. The opening portion serves as an entrance / exit 46 through which the belt 53 enters and exits from the insertion portion. Incidentally, the entrance / exit 46 is formed in a taper shape in which the widths of both right and left ends widen downward.

  The buckle 43 is formed in a flat rectangular parallelepiped shape, and has an insertion port (not shown) through which the tongue 51 is inserted and connected and fixed to the tip portion which is the end opposite to the belt 53 side of the buckle 43. Is formed. After the belt 53 is inserted into the insertion part 44 of the buckle holding part 31 and the buckle 43 is positioned above the buckle holding part 31, the base end part side that is the end part of the buckle 43 on the belt 53 side is the holding part. The buckle 43 is inserted into the buckle holding portion 31 so as to be inserted from the upper end of the insertion portion 44 of 31. In other words, the upper end of the insertion portion 44 of the buckle holding portion 31 becomes the insertion port 44a for inserting the buckle 43, and the opened lower end of the buckle holding portion 31 is not open to the extent that the buckle 43 can be inserted.

  In the buckle 43, an inclined surface 43a is formed on the surface (non-operator side surface) opposite to the surface (operator side surface) facing the operator side when the seat belt is mounted, inclined toward the base end side so as to approach the operator side surface. ing. The slope 43 a is located in the proximal half of the buckle 43. Correspondingly, a regulation surface 45 inclined downward toward the inner wall surface on the near side is formed on the inner wall surface on the side far from the seat 13 among the left and right inner wall surfaces constituting the insertion portion 44, The degree of inclination of the regulation surface 45 is set to be substantially the same as the slope 43a described above (see FIG. 7).

  For this reason, when the buckle 43 is inserted into the buckle holding part 31 from the base end side with the mounting surface facing the seat side (right and left inner side), the inclined surface 43a comes into surface contact with the regulating surface 45 and further downwards. The buckle 43 can be stably accommodated and held in the buckle holding portion 31. By the way, when the buckle 43 is inserted into the buckle holding portion 31 from the base end side with the mounting surface facing left and right outside, the base end portion of the buckle 43 is hooked on the regulation surface 45 or the vicinity of the regulation surface 45. The buckle 43 cannot be accommodated and held in the buckle holding part 31.

  That is, the buckle 43 can be inserted into the insertion port 44a from the upper side only when the base end of the buckle 43 faces downward and the operator side of the buckle 43 faces the left and right inside (seat side). Thus, the buckle holding part 31 is configured.

  Further, as described above, in order to house and hold the buckle 43 in the stowed position in the buckle holding part 31, it is necessary to insert the buckle 43 up and down through the holding part of the belt 53 on the buckle base end side. When removing from the buckle holding part 31, it is necessary to take out the belt 53 from the buckle holding part 31, and such a belt 53 is taken in and out through an entrance 46 opened in a slit shape. Incidentally, as described above, the entrance / exit 46 is formed in a tapered shape that expands in the left-right width downward, so that the belt 53 can be smoothly taken out from the buckle holding portion 31 by grasping and lifting the belt 53. It becomes possible. By the way, the belt 53 is bent and deformed to reduce the belt width, so that the belt 53 can be smoothly put in and out of the holding portion.

  As shown in FIGS. 8 to 11, the tongue holding portion 32 described above is positioned between a pair of locking pieces 54, 54 integrally formed on the inclined surface 38 and the locking pieces 54, 54. It is comprised from the control part 58 which bulged from the inclined surface 38 to the seat 13 side. The pair of locking pieces 54, 54 are respectively bent with respect to the base end side half projecting from the inclined surface 38 toward the seat 13, so that the front end side half faces each other, and formed in a bowl shape as a whole. Has been.

  A slot-like insertion space 57 into which the tongue 56 is inserted is inserted between the locking piece 54 and the bulging end surface of the restricting portion 58. The insertion space 57 is formed by the above-described configuration. Part of the seat 13 side and the top and bottom are opened. Incidentally, the upper end of the insertion space 57 is set to the insertion port 57a for inserting the tongue 56, and the upper end portion of each locking piece 54 is on the side away from the inclined surface 38 in order to open the insertion port 57a more widely. The curved portion also functions as a tapered guide portion 59 that smoothly guides the tongue 56 toward the insertion space 57.

  On the other hand, the tongue 56 accommodated and held in the tongue holding portion 32 is composed of a metal tongue plate 56a inserted into the insertion port of the buckle 43 and a rectangular thick plate-like attachment body 56b. The attachment body 56b has a distal end portion of the belt 53 attached to one of the pair of long side portions and a base end portion of the tongue plate 56a attached and fixed to the other. Incidentally, the base end portion of the belt 53 is fixed to the rear side of the seat 13.

  The tongue plate 56a is formed so that the insertion width of the tongue plate 56a is narrower than the insertion width of the attachment body 56b, and the thickness of the tongue plate 56a is thinner than the thickness of the attachment body 56b. More specifically, the tongue plate 56a and the attachment body 56b are integrally connected to form a continuous flat surface on the surface (operator side surface) facing the operator side when the seat belt is mounted, while the seat belt is mounted. On the surface (non-operator side surface) that sometimes faces away from the operator side, the attachment body 56b protrudes in a convex shape with respect to the tongue plate 56a (see FIG. 11).

  As described above, the non-operator surface of the tongue 56 is directed to the seat side (right and left inner side) and the front end of the tongue 56 is switched to the storage posture, and the front end of the tongue 56 in the storage posture is inserted from the upper side into the insertion port. By inserting the tongue plate 56a into the insertion space 57, the tongue plate 56a can be accommodated in the insertion space 57, and the upper end of the tongue holding portion 32 of the mounting body 56b. The tongue 56 is stably held by the tongue holding portion 32 by the reception at.

  Incidentally, the thickness of the insertion space 57 is set to be slightly thicker or substantially the same as the thickness of the tongue plate 56a, and is formed thinner than the attachment body 56b. For this reason, in a state where the non-operator side surface of the tongue 56 is directed to the left and right sides, the attachment body 56 b contacts the inclined surface 38 and the tongue 56 cannot be inserted into the tongue holding portion 32. Further, when the tongue 56 is inserted into the lower side or the tongue holding portion 32, the tongue 56 is pulled out of the tongue holding portion 32 and falls by its own weight.

  That is, the tongue 56 can be stored and held in the tongue holding portion 32 only when the front end of the tongue 56 faces downward and the operator side of the tongue 56 faces left and right. The tongue holding part 32 is comprised.

  With this configuration, the buckle holding portion 31 and the tongue holding portion 32 are each configured to be in the vicinity of the rear side of the seat 13 and to be located below the gripping portions of various operation levers. The operator can change from the stored state (stored posture) in which the buckle 43 and the tongue 56 are stored in the holding portions 31 and 32 to the mounted state in which the operator is wearing the seat belt without changing the posture from the sitting posture. Since the buckle 43 and the tongue 56 can be switched between the storage posture and the mounting posture without performing the operation of twisting the 53, the seat belt can be easily stored and mounted.

  Further, in either the accommodated state or the attached state, the holding portions 31 and 32 or the buckle 43 or the tongue 45 accommodated in the holding portion do not interfere with the forward / backward swing operation of each operation lever.

Next, based on FIGS. 4 to 15, the configuration of the accommodating portion and the cup holder portion provided in the fender cover will be described.

It is arranged on the right (right and left outside) side in the left-right direction.

  The accommodating portion 33 is formed by a rectangular frame-shaped frame wall, and a partition portion 61 (partition) is provided at the center portion in the front-rear direction to provide a first accommodating space 33a on the outer side in the left-right direction and an inner side in the left-right direction. It is divided into the second accommodation space 33b. Each of the storage spaces 33a and 33b has a height of an outer wall portion and a partition portion 61 that form the first storage space 33a so that small items stored in the first outer storage space 33a can be easily taken in and out from the seat side. In comparison, the height of the outer wall portion forming the second accommodation space 33b is reduced.

  Among the storage spaces, the first storage space 33a arranged outside is configured to store and hold at least a part of the tank cap 9 that is screw-engaged to the fuel filler port 8 by a turning operation. Yes. Specifically, a plurality of grip portions 9a are provided on the peripheral surface of the cylindrical tank cap 9 so that the cylindrical cap can be easily opened and closed by a turning operation. In this state, the grip portion 9a is locked to the front and rear ends of the first storage space 33a, and the tank cap 9 is held in the first storage space 33a.

  The second storage space 33b is formed so that the fuel cap 62 of the fuel tank used when fueling the fuel tank can be stored in the vertical direction (see FIGS. 12 to 15).

  As shown in FIGS. 4 to 9, the cup holder portion 34 is located behind the assist bar side fixing portion 41 of the left fender cover 23 </ b> L and in the front view, the main transmission operation lever 24, the auxiliary transmission lever 26, and the like. The PTO speed change lever 27 is arranged on the left side in the left-right direction (outside left and right) from the range in which the PTO shift lever 27 is operated to swing.

  Further, the cup holder portion 34 is formed in a columnar shape raised to a predetermined height so that the cup and the like accommodated by vibrations during work traveling and the like are not dropped, and is accommodated in the cup holder portion 34. A cutout 34a is formed on the upper end seat side of the cup holder 34 (see FIGS. 4 and 5) so that it can be easily taken out.

  With this configuration, the mounting table 12 arranged on the right side of the traveling machine body 7 is switched to the mounting posture, and the tank cap 9 screwed to the fuel filler port 8 is mounted with the fuel tank placed on the mounting table 12. When removing and refueling the fuel tank, the tank cap 9 and the refueling cap 62 attached to the refueling tank are integrally formed on the right fender cover 23R on the right side of the traveling machine body 7 on the same side as the refueling port 8 side. Since it can hold | maintain in the said 1st storage space 33a and the 2nd storage space 33b, a fuel supply operation | work can be performed efficiently. Furthermore, since it can be used as an accessory case at times other than during refueling work, there is no waste.
