Title:
STRAIN DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/089872
Kind Code:
A1
Abstract:
According to the present invention, a cover of an enclosure for a strain detection device has a cylindrical peripheral wall section, a disc-shaped top plate section that closes the upper end of the peripheral wall section, and a reinforcing section that protrudes from the top plate section. The volume of the cover is at least 15% and less than 40% of the volume of a cylinder including the upper surface of the top plate section, the outer circumferential surface of the peripheral wall section, and the bottom surface of the peripheral wall section. In the strain detection device, the top plate section of the cover has a maximum deformation of at most 4.1% of the outer diameter of the cover, said deformation being in the central axial direction of the peripheral wall section and being due to the differential pressure between the internal pressure of an interior space of a case sealed by the cover and the air pressure of a tire.
