用センサー。 It has a cylindrical case 8 and a rod 9 that is inserted and held in the cylindrical case 8 so as to be slidable and telescopically movable in the axial direction of the cylindrical case 8. In addition, the rod 9 is provided with an electric contact 15 for detecting the amount of expansion and contraction of both 8 and 9 as a voltage change by changing the sliding contact position of the electric resistor 12. A sensor for detecting length,
The cylindrical case 8 consists of a case body 8A and a lid 8B, and a recess 20 is formed inside the lid 8B, and a ventilation hole 22 is formed in the lid 8B to communicate the recess 20 to the outside of the case. The length detection sensor is provided with a non-breathable and stretchable membrane 23 that blocks the recess 20 from the inner space of the case 8.
