Abstract
A detection device includes a strain generator that includes a body including a first end and a second end, and a through-hole penetrating through the body in a direction that connects a first side on which the first end is located and a second side on which the second end is located, where a bolt of a fastening mechanism is to be inserted into the through-hole; a strain sensor that is configured to detect strain of the strain generator caused by a fastening axial force that is applied by the fastening mechanism in an extending direction of the through-hole; and a casing that is configured to house at least a part of the body of the strain generator along a first outer side surface of the body.
Claims18
A detection device, comprising:
- a strain generator that includes
- a body including a first end and a second end, and
- a through-hole penetrating through the body in a direction that connects a first side on which the first end is located and a second side on which the second end is located, where a bolt of a fastening mechanism is to be inserted into the through-hole;
- a strain sensor that is configured to
- detect strain of the strain generator caused by a fastening axial force that is applied by the fastening mechanism in an extending direction of the through-hole;
- and
- a casing that is configured to
- house at least a part of the body of the strain generator along a first outer side surface of the body, wherein
- the strain generator includes
- a projection that projects outward, in a plan view, of the first outer side surface, the projection being provided in at least one at the first outer side surface in a circumferential direction that encloses the through-hole,
- the casing includes
- a facing wall that faces the first outer side surface, and
- the facing wall includes
- a recess that is recessed outward in the plan view and is configured to house the projection.

- and
- a casing that is configured to
- house at least a part of the body of the strain generator along an outer side surface of the body, wherein
- the strain generator includes
- a flange that projects outward, in a plan view, of the outer side surface of the body,
- the flange includes
- a cutout portion that is cut out inward, in the plan view, of an outer periphery of the flange, the cutout portion being provided in at least one at the outer periphery of the flange in a circumferential direction that encloses the through-hole,
- the casing includes
- a facing wall that faces the outer periphery of the flange, and
- the facing wall includes
- a projection that projects inward in the plan view and is configured to be housed in the cutout portion.
