Abstract:
1. A foreign matter detection sensor comprising: an elongated sensor section, which includes an elongated elastic hollow insulating body and a plurality of electrode wires arranged inside the hollow insulating body to be separate from each other, wherein the sensor section includes a first end and a second end in a longitudinal direction, and the sensor section detects foreign matter by receiving external force from the foreign matter and being elastically deformed; power supply members, which are electrically connected to the electrode wires drawn out from the hollow insulating body at the second end of the sensor section via electrode connecting portions, wherein each power supply member includes a direction changing section, which extends from the associated electrode connecting portion in a direction intersecting the longitudinal direction of the sensor section and further extends in a direction toward the first end of the sensor section; and a sealing member, which is provided on the second end of the sensor section, wherein the sealing member incorporates and seals the electrode connecting portions, the direction changing sections, and one longitudinal end of the hollow insulating body corresponding to the second end of the sensor section; wherein the power supply members are each formed by a terminal and a lead wire, the terminals are arranged to be adjacent to the second end of the sensor section electrically connected to the electrode wires, and the lead wires are electrically connected to the terminals, and wherein: the sealing member incorporates and seals the terminals, lead wire connecting portions, which connect the terminals to the lead wires, the electrode connecting portions, and one longitudinal end of the hollow insulating body corresponding to the second end of the sensor section, the lead wires are arranged relative to the terminals such that the angle formed by the longitudinal direction of the lead wires and the longitudinal direction of the sensor section is less than or equal to a right angle, and the lead wire connecting portions are displaced relative to the electrode connecting portions in a direction orthogonal to the longitudinal direction of the sensor section on the terminals to approach draw-out positions at which the lead wires are drawn out from the sealing member.
