The lower portion is mounted to the floor pan .1by several bolts 14. Likewise, at its upper end, it issecured by 'several bolts 16 to that part <strong>of</strong> the floorwhich is normally referred to as the toe board 18.The accelerator pedal assembly <strong>in</strong>cludes a base,bracket member 20, an accelerator pedal 22 h<strong>in</strong>gedlyconnected by h<strong>in</strong>ge p<strong>in</strong> 24 to the lower portion <strong>of</strong> thebase bracket member, an upper hous<strong>in</strong>g portion 26which is part <strong>of</strong> the base bracket member and <strong>in</strong>cludes IScertan electrical components affxed thereto <strong>in</strong>clud<strong>in</strong>ga potentiometer 28 and an idle validation switch 30, andan oscilat<strong>in</strong>g follower member 32 pivotally connected'to the free end <strong>of</strong> the accelerator pedal <strong>for</strong> translat<strong>in</strong>gthe motion <strong>of</strong> the accelerator pedal to the electrical 20components 28 and 30.More specificaly, it is seen that the base bracketmember 20 is <strong>in</strong> the <strong>for</strong>m <strong>of</strong> an elongated plate member.-It <strong>in</strong>cludes a lower portion 34 which is generally horizontalto the floor pan 12, and an upper porton 36 25arranged generally vertically. At the midpo<strong>in</strong>t <strong>of</strong> thebase bracket member 20, which is generally at thejuncture<strong>of</strong> the upper and lower portions there<strong>of</strong>, there islocated a stop member 38 which projects upwardly <strong>in</strong>the direction <strong>of</strong> the accelerator pedal 22 and acts as a 30stop <strong>for</strong> the accelerator pedal represent<strong>in</strong>g the wideopen-throttleposition. At the extreme upper end <strong>of</strong> the "base bracket membe, the hous<strong>in</strong>g portion 26 is <strong>for</strong>medby two laterally spaced and outwardly project<strong>in</strong>g walls40 and 42.

For thispurpose, the rotary shaft can be flattened throughout itslength on a m<strong>in</strong>or arc portion <strong>of</strong> its circumference asshown at 74 <strong>in</strong> FIGS. 4 and 5.
