Title:
STRAIN DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/161986
Kind Code:
A1
Abstract:
The present disclosure provides a strain detection device that can be made more compact than previous functional components and can demonstrate an improvement in strain detection accuracy, without hindering tire deformation. One embodiment of the present application comprises: a housing 110 that is adhered to an inner circumferential surface Ti of a tire T via an elastic adhesive EA; and a recess 111c that is provided in an end surface 111e of the housing 110, said end surface 111e facing the inner circumferential surface Ti of the tire T. Additionally, a strain detection device 100 comprises: a strain detection element 120 that is positioned in a center section of the recess 111c and detects the strain of the tire T via the elastic adhesive EA; and an elastic member 130 that is positioned in an inside peripheral edge section of the recess 111c and protrudes farther toward the inner circumferential surface Ti of the tire T than the end surface 111e of the housing 110. The elastic adhesive EA is filled into a space that is inside of the elastic member 130 and between a bottom surface 111b of the recess 111c and the inner circumferential surface Ti of the tire T.
