Anti-falling transverse stopper

The utility model belongs to the technical field of vehicle vibration reduction, and particularly relates to an anti-disengagement type transverse stopper. The transverse stopper comprises a base, a friction plate and a rubber body, the base comprises an annular cylinder, and a plurality of through holes distributed in the circumferential direction of the annular cylinder are formed in the cylinder wall of the annular cylinder in a penetrating mode. The friction plate comprises a core shaft which is arranged in the annular cylinder in a penetrating mode. The rubber body is bonded between the annular cylinder and the mandrel in a vulcanization mode and comprises a body and a plurality of protruding columns, the body is formed between the inner wall of the annular cylinder and the shaft wall of the mandrel, and the protruding columns are formed in the through holes in a one-to-one correspondence mode. The transverse backstop is simple in structure and high in practicability, the possibility that the rubber body
