Abstract
A leveling plate including a main body and an end protrusion. The end protrusion is provided at both ends in a longer side direction of the main body, and protrudes from the main body in a thickness direction, the end protrusion having an end circumferential surface whose central axis extends in parallel with a shorter side direction of the main body.
Claims16
A leveling plate, comprising:
- a main body including a surface extending in first and second directions orthogonal to each other;
- an end protrusion which is provided respectively at both ends of the main body in the first direction, and protrudes from the main body in a third direction perpendicular to the surface, the end protrusion having an end circumferential surface whose central axis extends in the second direction of the main body;
- and
- an intermediate protrusion which is provided between the end protrusions of the main body in the first direction, and protrudes from the main body to an opposite side of the end protrusions in the third direction, the intermediate protrusion having an intermediate circumferential surface whose central axis extends in the second direction of the main body;
- wherein letting an imaginary line connecting a central axis of the intermediate circumferential surface with a central axis of the end circumferential surface be a line L1, and an imaginary line which is tangent to each tip end of the end protrusions be a line L2 in a section perpendicular to the central axis of the end protrusion, an angle α formed by the line L1 and the line L2 is a≤55°.
