The invention provides an automobile seat height adjusting transmission device. The automobile seat height adjusting transmission device comprises a shell (1) and a cover plate (2). The shell (1) is provided with a first through hole. The cover plate (2) is provided with a second through hole. The lower end of the shell (1) is connected with the cover plate (2). The automobile seat height adjusting transmission device further comprises a first-level overrun clutch and a second-level overrun clutch, wherein the first-level overrun clutch is arranged on the input side and used for carrying out transmission or isolation control over the rotation torque of the output side through handle operation, and the second-level overrun clutch is arranged on the output side and used for transmitting the input torque from the input side to the output side and isolating the reverse input torque from the output side. The transmission structure of a pin roller type both-way overrun clutch structure has the beneficial effects of being low in weight, high in strength, stable in running, safe, reliable and the like. A both-way volute spring structure is adopted, the structure of the transmission mechanism is more compact, and the transmission torque is more stable and reliable.
