<p>A footrest plate has a footrest side and a rear side opposite to the footrest side. The rear side is provided with a pair of clips (30, 31) to be fixedly received into a pair of corresponding mounting holes (41, 42) formed in a workpiece (39). The pair of clips are disposed with leaving a certain distance therebetween in the longitudinal direction of the footrest plate, in alignment with the pair of corresponding mounting holes disposed with leaving a certain distance therebetween. Each of the clips has a rectangular cross-sectional insertion portion insertable into corresponding one of the mounting holes each formed in a rectangular shape. The rear side is further provided with a reference protrusion (45) at an intermediate position between the pair of clips (30, 31) disposed with leaving the certain distance therebetween in the longitudinal direction. The reference protrusion (45) is insertable into a reference hole (43) formed in the workpiece. The reference protrusion (45) is formed in a rectangular cross-section defining a pair of lateral sides each of which extends in a lateral direction intersecting the longitudinal direction and has a length greater than that of each lateral side of the clips extending in the lateral direction.</p> |
