Here, the guide structure refers to a structure including the bracket 40 and the guide 20 made of resin. The bracket 40 shown in FIGS. 4 and 5 forms part of a bracket for attaching the front wheel 16, the rear wheel 17, the tread plate 13 and the like shown in FIG.

  The bracket 40 partially forms a plate-like body. The plate-like body of the bracket 40 is provided with a fitting portion 41 having a taper 42 to form a depression (concave portion). The guide part of the resin guide 20 fits in, the groove part 22 of the resin guide 20 fits in the plate-shaped body of the bracket 40, and the resin guide 20 is detachably attached to the bracket 40.

  The resin guide 20 has a structure in which guide pillars 21 and 21 are planted on a circular guide portion 23 and a groove portion 22 is formed, and the groove portion 22 is provided with a guide portion 24 for guiding a taper 42 of the bracket 40. ing. The guide part 24 has a structure protruding in the groove part 22. And the guide 20 which has a structure shown in FIG. 4 is integrally molded with resin. However, each component of the guide 20 may have a structure in which the circular guide portion 23 is bonded and fixed.

  As shown in FIG. 5, in a state where the resin guide 20 is attached to the bracket 40, the plate-like body of the bracket 40 is attached so as to fit into the groove portion 22 of the resin guide 20. In this mounting operation, the two guide columns 21 and 21 make it easy to insert the plate-like body of the bracket 40 by the chamfers 27 and 27 at the ends thereof, and further, the guide columns 21 and 21 face each other with a gap between the guide columns 21 and 21 facing each other. The body is guided and inserted into the groove 22.
