Title:
COMPONENT HAVING TOP PLATE AND SIDE WALL
Document Type and Number:
WIPO Patent Application WO/2019/198727
Kind Code:
A1
Abstract:
In a component having a side wall comprising a curved portion, vibration of the component causes elastic deformation of the side wall so as to open outwardly or incline inwardly. During such deformation, stress is generated in the base of the side wall, and repeated occurrence of stress causes fatigue cracks at the base. This component has a top plate and a side wall formed by bending the periphery of the top plate and has an open cross section in a direction perpendicular to the top plate. The side wall includes a curved portion that has a shape protruding or recessed toward the inner side of the component as viewed from a direction perpendicular to the top plate, and that is curved with a curvature radius of 300 mm or less. A reinforcing member which is joined to the side wall is provided at least on a portion of the curved portion.
