Title:
POSITION DETECTION SENSOR
Document Type and Number:
WIPO Patent Application WO/2020/208920
Kind Code:
A1
Abstract:
A position detection sensor 70 comprises a rod-form contact part 80 of which the outer peripheral surface on a distal-end side comes into contact with an object and turns about a proximal-end side along with displacement of the object, a movable part 73 that moves due to the turning of the contact part 80, and a magnetic switch 72 that senses the presence of the movable part 73 and detects the position of the object when the movable part 73 comes to a prescribed distance by moving. The contact part 80 has a tubular outer-side member 81 that has elasticity and constitutes the outer-peripheral side of the contact part 80, and a rod-form inner-side member 82 that is inserted through the inner side of the outer-side member 81 and that has a greater modulus of elasticity than the outer-side member 81.
