それもある。However, since the above-mentioned conventional mobile gas leakage inspection apparatus performs a gas leakage inspection while pushing the base by hand, it can be said that it has wheels. Since the gas collection port is pressed while grounded, it has the effect of suppressing the suction of surrounding air and increasing the detection sensitivity of leaked gas, but it requires power to move and it is difficult to increase the moving speed. However, there is a problem that the inspection work takes time, and when the gas collection port slides on the road surface, the moving speed is increased, so that sand and dust are sucked together with the collected gas. In addition, there is also a problem that inspection troubles such as changing the sensitivity of gas detection are liable to be caused due to clogging of the suction path, deterioration of the gas sensor and deterioration of durability due to sand and dust. In addition, when the periphery of the gas collection port is slid on the road surface, as a result, when the road surface is greatly uneven due to aging of the road or the like, the gap between the periphery of the gas collection port and the road surface is reduced. A large gap is formed in the gap, and the air sucked from the surroundings through the gap causes sand and dust to be sucked together with the trapped gas in the same manner as when the moving speed is increased. As a result, the trapped gas is diluted, resulting in a reduction in detection sensitivity. In order to solve the problems of the inspection labor and inspection speed, it is conceivable that the vehicle is an automobile. However, if the vehicle is equipped with a gasoline engine or a diesel engine, the organic gas component in the exhaust gas from the prime mover is sucked. In some cases, erroneous detection may occur, and the gas pipe is usually buried near the shoulder of the road. Therefore, it becomes an obstacle to move the suction port along the buried pipe. Especially when buried on the sidewalk,
Since it is necessary to drive a car on the sidewalk, it is not preferable from the viewpoint of road traffic safety. In addition, if a vehicle for inspection is used and it is determined that the vehicle is an inspection vehicle, there is a possibility that the residents may feel uneasy even in the case of a periodic inspection of an urban area.

さら住民に不安感を与えることがない。According to the first aspect of the present invention, a gas leak inspection can be quickly performed along a buried portion of a gas pipe while tracing the buried pipe. In other words, if a tricycle is used for the vehicle, it is possible to use a commercially available tricycle as it is, and the vehicle is unlikely to overturn, and the traveling drive is easy. It is easy to increase the speed. Furthermore, it is easy to dispose the housing box of the gas detecting means above the axle provided with the two wheels of the three-wheeled bicycle, and the gas suction port of the gas detecting means is arranged so as to be separated from the ground. Therefore, the height position with respect to the road surface is stabilized, and the detection sensitivity of the leaked gas leaking onto the road from the road surface by the gas suction port does not largely change. Further, the gas suction port of the gas detection means is arranged below the housing box, and the housing box covers the upper side of the gas suction port. There is no influence of rainfall around the suction port, and it is possible to suppress an obstacle to detection of leaked gas due to rainwater. In addition, if a motor-driven bicycle is not used, traveling on the sidewalk is safe and is not affected by the exhaust of the motor, so that there is no problem of erroneous detection. For example, using a three-wheeled bicycle with two front wheels and arranging the housing of the gas detecting means on the front wheels, it is possible to detect leaked gas during traveling without being affected by the passage of the front wheels. In addition, since it is a normal tricycle and the suction part is installed in a position that is difficult to see from the outside, it does not look like a special inspection device and does not give the residents a feeling of anxiety when testing in the city area .

排気がないので、空気の汚染をもたらすことがない。According to a second aspect of the present invention,
The labor required for gas leak inspection can be further reduced. In other words, since a motor-equipped bicycle is used, there is no problem of erroneous detection of exhaust gas even if the bicycle is a motorized one.Moreover, since it can be driven by an electric motor, it is possible to reduce the driving driving labor and achieve quick gas Leak inspection can now be performed. The motor-equipped bicycle may be a power-assisted bicycle or a bicycle that can be driven exclusively by an electric motor. In particular, by using a motor-equipped bicycle, the traveling speed other than the inspection traveling can be improved, and the labor required for traveling can be greatly reduced. Moreover, since there is no exhaust, no air pollution is caused.

なる。Further, according to the characteristic configuration of the third aspect, a stable gas leakage inspection can be performed. In other words, if the position of the gas suction port is fixed with respect to the axle, there is no swing of the gas suction port, and the distance to the road surface is stable. It is possible to prevent the sensitivity of the leaked gas from being lowered without affecting the rate of change. In addition, with such a configuration, when a shock absorbing mechanism is provided between the axle and the housing box of the gas detecting means for protection of the gas detecting means, the shock absorbing mechanism is provided between the axle and the vehicle body. By providing a mechanism, it is also possible to reduce the fatigue of the inspection operator at the same time.
