STRAIN SENSOR AND LOAD DETECTOR USING SAME

摘要

A strain sensor includes a cylindrical strain body extending in an axial direction, a first fixed part, a second fixed part, and a strain detection element. The first fixed part is connected to the strain body at a first connection part and extends from an opening of a first end of the strain body in the axial direction. The second fixed part is connected to the strain body at a second connection part and extends from an opening of a second end of the strain body in a direction opposite to the first fixed part with a gap interposed between the strain body and the second fixed part. The strain detection element is disposed such that a center of the strain detection element is closer to the second fixed part than a center of the gap in the axial direction.

主权项

1. A strain sensor comprising:
a cylindrical strain body extending in an axial direction; a first fixed part connected to the strain body at a first connection part and extending from an opening of a first end of the strain body in the axial direction, the first fixed part including a first engagement part to be fixed to an object to be detected; a second fixed part connected to the strain body at a second connection part and extending from an opening of a second end of the strain body in a direction opposite to the first fixed part with a gap interposed between the strain body and the second fixed part, the second fixed part including a second engagement part to be fixed to the object to be detected; and a strain detection element provided on an outer peripheral surface of the strain body, wherein the strain detection element is disposed such that a center of the strain detection element is closer to the second fixed part than a center of the gap in the axial direction.
