The invention discloses an automatic clearance adjusting device for a multi-disc wet brake, and relates to the technical field of automatic adjusting devices. Comprising an elastic bush, a piston, a reset device and a friction plate assembly, the elastic bush is formed by bending an elastic steel sheet, so that the whole elastic bush has elasticity in the radial direction, friction is better generated between the elastic bush and a through hole of the piston, and then good automatic clearance adjustment is achieved; the elastic bushing is simple in structure and is provided with the notch, so that the whole elastic bushing can be conveniently pressed into the through hole of the piston, the problems that the clearance adjusting device bushing and the piston are easy to abrade in interference fit and the magnitude of interference cannot be accurately guaranteed are solved, stable friction force can be provided, meanwhile, the reset spring is added, the piston reset function is integrated, and the service life
