PURPOSE: An impact detecting device is provided to sufficiently receive a resin melted by a laser in a housing unit and an inner resin channel of a connector unit without a leakage of the resin to outside, thereby preventing the leakage of the resin. CONSTITUTION: An impact detecting device comprises a housing unit(50) and a connector unit(60). The connector unit comprises an insertion portion(66) and a connection portion(62). A mounting space(68) of the insertion unit is connected to an internal space(56) of the housing unit. The connector unit is inserted into an insertion space(62') of the connection portion. A welding rib(80) is protruded in one of an edge of an inlet of the internal space of the housing unit and a portion of the connector unit in contact with the inlet. A resin channel(82) is formed along the welding rib. A through-hole(84) horizontally passes through the welding rib. |
