Abstract: A motorized beach vehicle has a gear lever clutching structure for prevention of gear slip. The gear lever, the linking arm and the swing arm are connected to form a substantially “h”-shaped structure. The gear lever may be pivoted to combine the combination stud of the swing arm with the combination hole of the combination arm, so that the gear lever may be moved to shift the universal connector of the crank so as to change the speed. After the gear lever accomplishes the gear shifting work, the combination stud is detached from the combination hole of the combination arm. Thus, the crank cannot be moved to shift gear in the gearbox due to vibration or shock applied on the vehicle body, thereby preventing from incurring gear slip of the gearbox of the motorized beach vehicle.
