Abstract

PURPOSE:To improve the assembly of the titled seismoscope by enabling to asemble a contact block constituting an output part from the lower part of the body of the sensor and making the assembling direction of the contact block coincide with that of other parts. CONSTITUTION:The body 1 of a seismoscope is molded so as to unify a case part 2 and a fitting part 7. The case part 2 is provided with a bowllike bottom 3 and a recessed reciever 4 and a through-hole 5 that are arranged in the center of the bottom, and a lid 6 is sealed and fixed on the opening part of the case. A steel ball 14 is arranged on the bottom 3 of the case part so as to rotate freely and the upper end of an operation shaft 15 inserted into the through-hole 5 so as to move freely in the vertical direction is arranged so as to contact with the steel ball. In a contact block 17, a fixed terminal 22 opened always is pressed in and fixed on a press-in groove 21 to which a common terminal 18 and a fixed terminal 19 closed always are inserted to be molded. The block 17 is fitted and fixed to the lower part of the installing part 7.
