PURPOSE:To attain waterproofing, and fixing of an output terminal, by a simple structure, by storing a piezoelectric element and a weight in a housing member, and supporting a detecting output terminal by a socket which is fitted into the housing in a waterproof manner. CONSTITUTION:To the inside of a housing 1 having a fitting mechanism 1a to an object to be measured, a piezoelectric terminal 3, an electrode terminal 4 and a weight 2 are screwed 5. From the upper part of the housing 1, a socket member 15 is fitted in through an ''0'' ring 18, and it is formed as one body with the housing by a caulking part 16. One end of the electrode terminal 4 is connected to one end of an output terminal 14 held by the socket member, in an opening part 15b, and this opening part is filled with a sealing material 16. |
