The remaining two hook engaging holes 83 are separated from the lower top portion 85a in the left-right direction and are separated in the front direction and the lower direction to the upper end portion (fitting edge portion 82a) of the side wall of the lower bulging portion 85. Is provided.

  Each hook engagement hole 83 has a substantially rectangular shape in a rear view and is formed so as to penetrate the fitting edge portion 82a (the upper end portion of the lower bulging portion 85). A cover portion 83a is provided in each of the two hook engaging holes 83 formed on the outer side in the left-right direction. Each cover part 83a is formed in a rectangular box shape with the lower surface opened, and is provided so as to close the hook engaging hole 83 from the front side (see FIG. 10A).

  The two pin engaging holes 84 as the second engaged portions are provided in the upper portion of each rack forming portion 82 c of the support portion 82. Specifically, each pin engagement hole 84 is formed through a substantially plate-like projecting piece 84a extending upward from the top of each rack formation portion 82c on the center side in the left-right direction of each rack formation portion 82c. . Each pin engagement hole 84 is formed in a substantially rectangular shape in rear view. The two pin engagement holes 84 are disposed above and in front of the three hook engagement holes 83 in a side view, and are located more centrally than the pair of left and right hook engagement holes 83 in a rear view. Each pin engagement hole 84 (projection piece 84 a) is located above the lower fixing hole 86.

  The lower shield 80 includes a pair of left and right fourth rear through holes 90, a pair of left and right fifth rear through holes 91, a pair of left and right sixth rear through holes 92, and a pair of left and right seventh rear through holes. It has a hole 93 and three rear hooks 94. The pair of left and right fourth rear through-holes 90 are formed in protruding pieces 90a extending upward from the upper part on the left and right outer sides of each rack forming portion 82c. The pair of left and right fifth rear through holes 91 are formed in protruding pieces 91a that extend from the outer surface of each rack forming portion 82c toward the left and right outer sides. The pair of left and right sixth rear through-holes 92 are formed in protruding pieces 92a extending from the left and right outer ends of the fitting edge portion 82a toward the left and right outer sides. The protruding piece 92a is overlaid on the fastening surface of the boss in which the rear screw hole 73 of the upper shield 60 is formed. The pair of left and right seventh rear through-holes 93 are formed on the left and right outer sides in the middle portion of the shield body 81 in the vertical direction. The three rear hooks 94 are formed at equal intervals in the left-right direction at the lower end of the shield body 81.

  Next, an assembly procedure (assembly structure) of the leg shield 31b will be described with reference to FIG. 3 and FIG. Here, FIG. 10A is a perspective view showing the engagement between the shield hook 64 and the hook engagement hole 83, and FIG. 10B shows the engagement between the shield pin 65 and the pin engagement hole 84. It is a perspective view.

  First, the worker arranges the upper shield 60 behind the support portion 82 of the lower shield 80. The operator aligns each shield hook 64 in each hook engaging hole 83, aligns each shield pin 65 in each pin engaging hole 84, and pushes the upper shield 60 forward with respect to the lower shield 80. .

  As the upper shield 60 is pushed, each shield hook 64 comes into contact with the fitting edge portion 82a (the edge portion of the hook engagement hole 83), and each shield hook 64 is connected to the upper bulging portion 67 of the upper shield 60. It spreads and displaces in the left-right direction due to elastic deformation. When the upper shield 60 is pushed further and each hook connecting portion 64b matches the hook engaging hole 83, the hook portion 64a enters the hook engaging hole 83 by the elastic force (restoring force) of the upper bulging portion 67. . By moving the upper shield 60 downward in this state, the fitting edge portion 82a of the lower shield 80 overlaps the rear side of the rear wall portion 63 of the upper shield 60 in the vehicle front-rear direction, and the hook connecting portion 64b is hooked. Engage with the lower front edge of the engagement hole 83 (see FIG. 10A). In addition to the effects of the shapes of the upper bulging portion 67 and the lower bulging portion 85, the hook connecting portion 64b regulates other than the movement in the direction in which the upper shield 60 and the lower shield 80 are separated from each other (vertical direction). Thus, the hook engaging hole 83 is engaged. By disposing each hook engaging hole 83 and each shield hook 64 as in this embodiment, the upper shield 60 engaged and placed on the upper side of the lower shield 80 can be stably supported. . The downward movement of the upper shield 60 that engages the shield hooks 64 with the hook engaging holes 83 may cause each shield hook 64 to contact the lower edge of the hook engaging holes 83 or the rear wall 63. The process ends when the lower end abuts against the step of the fitting edge 82a. It should be noted that the shield hook 64 that enters the two hook engaging holes 83 on the outer side in the left-right direction may abut against the cover portion 83a to restrict the pushing of the upper shield 60.

  Further, substantially simultaneously with the engaging operation of the shield hook 64 and the hook engaging hole 83, each protruding piece 84a moves to the front of each shield pin 65, and each shield pin 65 is inserted into each pin engaging hole 84. (See FIG. 10B). At this time, each projecting piece 84 a is elastically deformed while being guided by the tapered surface 65 a of the shield pin 65 and moves to the front of the shield pin 65. When the positions of the pin engagement holes 84 and the shield pins 65 are matched, the protruding pieces 84 a are deformed to the original positions, and the shield pins 65 are inserted into the pin engagement holes 84. Thus, the operator can easily and smoothly perform the fitting operation between the shield pin 65 and the pin engagement hole 84. Each shield pin 65 is fitted in each pin engagement hole 84 so as to restrict movement along the insertion direction (substantially front-rear direction) of the shield pin 65. By fitting the shield pin 65 and the pin engagement hole 84, the upper shield 60 and the lower shield 80, which are the only directions separating the hook engagement holes 83 and the shield hooks 64, are separated from each other. Movement is prevented. Thereby, the state in which the upper shield 60 and the lower shield 80 are integrated can be maintained. Further, since the upper surface of each shield pin 65 is formed so as to be farther from the shield hook 64 toward the tip side, the upper shield 60 rotates in the front-rear direction with respect to the lower shield 80. The shield pin 65 can be prevented from coming off from the pin engagement hole 84.

  As described above, when the upper shield 60 and the lower shield 80 are joined, the shield hooks 64 of the upper shield 60 engage with the hook engaging holes 83 of the lower shield 80. Further, each shield pin 65 of the upper shield 60 is fitted into each pin engagement hole 84 of the lower shield 80. The lower end portion of the front wall portion 62 of the upper shield 60 contacts the upper end portion of each rack forming portion 82c of the lower shield 80 (support portion 82) (see FIG. 6). The opening wall portion 61 and the rear wall portion 63 of the upper shield 60 cover a pair of left and right rack forming portions 82 c including a recess 87. A pair of left and right front racks 66 is configured by a space surrounded by the rear wall 63 and the recesses 87 (see FIG. 6). Each rack opening 66 a of the opening wall 61 disposed corresponding to the recess 87 is open to the top of the front rack 66. Thereby, the user can store small items in each front rack 66.

  Further, when the upper shield 60 and the lower shield 80 are joined, the lower bulge portion 85 is fitted inside the upper bulge portion 67, and the upper end portion of the shield body 81 is the rear wall portion 63. (See FIG. 6). The upper fixing hole 68 opened in the rear wall portion 63 of the upper shield 60 communicates with the lower fixing hole 86 opened in the support portion 82 of the lower shield 80.

  Subsequently, as shown in FIG. 3, the operator inserts the screw S <b> 1 into each sixth rear through hole 92 of the lower shield 80. The tip of each screw S1 is screwed into each rear screw hole 73 of the upper cover 40. That is, the protruding piece 92a in which the pair of left and right sixth rear through holes 92 is formed is fastened to the fastening surface of the boss in which the rear screw hole 73 is formed by the screw S1. As a result, the upper shield 60 is joined to the lower shield 80 to form a parted leg shield 31b. This tightening surface (tightening point) is a front side of the engagement position between the hook engagement hole 83 and the shield hook 64 and a position closer than the engagement position between the pin engagement hole 84 and the shield pin 65 in a side view. It is arranged on the rear side. Further, the tightening surface (tightening portion) is disposed below the fitting position between the pin engagement hole 84 and the shield pin 65 and the engagement position between the hook engagement hole 83 and the shield hook 64 in a side view. ing. With such an arrangement of the tightening points, the upper shield 60 and the lower shield 80 can be maintained in an integrated state even when the number of tightening is small. By tightening and fixing the screw S1, the relative movement between the upper shield 60 and the lower shield 80 is limited to a rotational movement around a straight line connecting the left and right tightening points. The movement of the upper shield 60 tilting backward with respect to the lower shield 80 is caused by the fact that each shield hook 64 comes into contact with the lower edge portion of the hook engagement hole 83 or the lower end portion of the rear wall portion 63 is fitted to the fitting edge portion 82a. It is regulated by coming into contact with the step. On the other hand, the movement of the upper shield 60 falling forward relative to the lower shield 80 is regulated by the support portion 82 of the lower shield 80, which is prevented from being displaced by the pin engagement hole 84 and the shield pin 65. .
