Title: Sensor
Inventor: TAGUCHI MASATAKA
IPC: G01N27/409
Filed: 2010-06-07
Abstract: PROBLEM TO BE SOLVED: To extend the lifetime of sealability in a sensor where a seal member disposed in a cylindrical body constituting the sensor and made of a rubber-like elastic material is compressively deformed into a constricted state from an outer peripheral surface to keep a lead wire passing through an insertion hole in the seal member, sealed.SOLUTION: A horizontal cross-section of a lead wire insertion hole 125 of a seal member 121 is formed into an elliptic shape having a radial direction of the seal member as a minor axis in a free state. In a prior art providing a circular cross-section in the free state, the seal member is largely deformed to have a direction orthogonal to the radial direction as a minor axis relatively when being compressed, so that a resin coating layer of the lead wire is strongly compressed in the minor axis direction to accelerate the reduction in sealability. In contrast, in a sensor, the cross-section is elliptic to have the direction orthogonal to the radial direction as a major axis in the free state, and therefore, the resin coating layer of the lead wire can be prevented from being strongly compressed in the direction orthogonal to the radial direction, by deforming the seal member so as to approximate the insertion hole after compression, to a circle, whereby the lifetime of sealability can be extended.
