A reversing mechanism for a toy motor driven wheeled vehicle having a driven axle with attached wheels supported on a chassis. The axle is supported on the chassis so that it is shiftable laterally relative to the chassis. The reversing mechanism includes an apparatus to shift the driven axle laterally relative to the chassis between forward and reverse driving positions upon engagement of the front or rear of the vehicle with the firm obstructing object. A pair of spur gears are positioned on the driven axle and are spaced in generally fixed relation to each other with each gear freely rotatable on the driven shaft. The shaft is freely slidable through the gears. A clutch member is affixed to the driven axle for rotation therewith and is positioned between the spur gears. The clutch member has rotationally opposite effective one-way clutch teeth on the sides thereof facing the spur gears. Complementary one-way clutch teeth are formed on the sides of the spur gears facing the clutch member and these are engageable with the complementary one-way teeth on the clutch member as the clutch member is moved into engagement with one of the spur gears and out of engagement with the other spur gear upon lateral shifting of the driven axle to one of the forward and reverse driving positions. A pair of oppositely rotatable idler gears are driven by the toy vehicle motor. Each idler gear meshes with one of the spur gears to thereby drive the driven axle through the spur gear that is in engagement with the clutch member.
