The utility model discloses a manual transmission and an automobile. The manual transmission comprises a gear reversing and shifting transmission fork mechanism. The gear reversing and shifting fork mechanism comprises a shift rail, a gear reversing transmission fork and a gear reversing rocker arm transmission fork. The shift rail is installed inside a shell of the manual transmission, the gear reversing transmission fork is connected to the shift rail in a matched mode and can move in the axial direction of the shift rail in a double-way mode, and one end of the gear reversing rocker arm transmission fork is connected to the gear reversing transmission fork in a pivoted mode. When the gear reversing transmission fork moves in the axial direction of the shift rail, one end of the gear reversing transmission fork and the gear reversing rocker arm transmission fork connected with the gear reversing transmission fork in the pivoted mode can convert front and back movement of the gear reversing transmission fork into left and right swinging movement of the other end of the gear reversing rocker arm transmission fork. The manual transmission is simple in structure and comfortable to use due to the adopted gear reversing and shifting transmission fork mechanism.
