The invention discloses a trundle brake device and a dish-washing machine and relates to the technical field of washing utensils. In order to solve the problems that an existing dish-washing machine is not convenient to move, can not achieve braking in time, has poor security and the like, the trundle brake device comprises a bracket and at least one trundle mounted on the bracket, and further comprises a rotary brake linkage bar mounted on the bracket and a brake device body for braking the trundles, wherein the brake linkage bar is connected with the brake device body through a transmission mechanism; when the brake linkage bar rotates in the first direction, the brake device body controls the trundles to be braked or releases braking of the trundles; when the brake linkage bar rotates in the first direction after resetting in the reverse direction, the brake device body releases braking of the trundles or controls the trundles to be braked. The invention further discloses the dish-washing machine comprising the trundle brake device. By means of the trundle brake device, the trundles can be braked in time, and braking and braking release are achieved only by rotating the brake linkage bar in one direction, so that security is improved.
