Claim Text:
1. An ultrasonic sensor assembly comprising: a hollow housing, a through hole being through-formed at one end of the housing, and an accommodating port being formed to be opened at the other end; a case inserted into and disposed at the through hole; a fixing member disposed between one end inner circumference surface of the housing and an outer circumference surface of the case to couple the case to the housing; a front supporting cover configured to comprise a side wall that is coupled to one end outer circumference surface of the housing and a supporting part that is formed to be bent in a direction from the side wall to the case and supports one surface of the fixing member; a piezo-electric element mounted on an inner bottom portion formed at one end of the case; a printed circuit board (PCB) disposed in the housing; a connection member, one end of the connection member being electrically connected to the piezo-electric element, and the other end being connected to an extension pin; and a sound-absorbing material charged into the case, wherein, an inner diameter of the supporting part is formed less than a maximum diameter of the fixing member, and one surface of the fixing member is supported by the supporting part, thereby preventing the case coupled to the fixing member from deviating in one end direction of the housing, and the extension pin is inserted into the housing in a state in which one end and the other end of the extension pin are exposed from the housing, the one end of the extension pin is connected to the connection member, and the other end of the extension pin is connected to the PCB.
