The utility model provides a worm gear and worm clearance adjusting mechanism, reducer and automobile, the worm gear and worm clearance adjusting mechanism comprises a plate spring structure, the plate spring structure is used for being connected to the inside of the reducer shell, and the plate spring structure is used for abutting against one side, far away from a worm gear, of a worm. Therefore, the worm moves towards the direction close to the worm gear. The plate spring structure can provide pushing force to push the worm towards the direction close to the worm gear, so that the gap between the worm gear and the worm is eliminated, and the effect of reducing abrasion and noise is achieved, and therefore the plate spring structure is adopted to replace a traditional worm gear and worm gap adjusting device, a complex assembly is simplified into a part of the plate spring structure, and cost is reduced. The function of eliminating the gap between the worm gear and the worm is achieved through the least part
