A manual unlocking device for a parking lock mechanism includes an operation lever that rotates when the parking lock mechanism is switched from a locked state to an unlocked state. The operation lever is arranged outside an occupant space of a vehicle cabin and is configured that a tool can be coupled to a rotation center thereof from the occupant space. The manual unlocking device for the parking lock mechanism is configured to switch the parking lock mechanism from the locked state to the unlocked state by integral rotation of the operation lever with the tool when the tool, which is coupled to the operation lever, rotates in a state where the tool is arranged on the rotation center of the operation lever.

A gear-shift lever module with various sensors integrated on one circuit board may include a module housing, the integrated circuit board disposed in the module housing, a position sensor, a manual mode switch and a connector. The position sensor senses a shift position of a gear-shift lever and is disposed on the integrated circuit board at a position corresponding to a hinge portion at a lower end of the gear-shift lever. The manual mode switch is disposed on the integrated circuit board at a position corresponding to a manual mode of the gear-shift lever and senses the manual mode by being pressed by the gear-shift lever when the gear-shift lever is positioned for the manual mode. The connector is electrically connected with the position sensor and the manual mode switch.
