Claim:
A toy boat comprising: a boat body; a driving source mounted on an inner side of the boat body; a housing mounted on an outer side of the boat body for turning movements between leftward and rightward positions relative to the boat body; a screw bracket mounted to the housing for turning movements therewith; a screw rotationally supported by the screw bracket, the screw being operably connected to and driven by the driving source so as to propel the boat body; a servo mechanism housed within the housing and having a transmission shaft operably configured to turn the housing and the screw bracket mounted thereto between the leftward and rightward positions so as to positionally adjust the screw supported by the screw bracket and cause the boat body to turn leftward and rightward, respectively, and an impact absorption mechanism operably connecting the boat body and the servo mechanism, wherein the impact absorption mechanism includes: (i) a support shaft mounted to the boat body having a first protrusion extending from an outer circumference of the support shaft and oriented in a direction of the support shaft, (ii) a shaft end portion operably connected at one end to the transmission shaft of the servo mechanism so as to be turned thereby in leftward and rightward directions and having a circular cylindrical section at an opposite end thereof, the shaft end portion having a second protrusion extending from an outer circumference of the circular cylindrical section and oriented in a direction of the shaft end portion, and (iii) an elastic C-ring member which surrounds and connects the support shaft and the circular cylindrical section of the shaft end portion, the C-ring member defining a gap for receiving and holding the first and second protrusions of the support shaft and the shaft end portion, respectively.
