FRAME STRUCTURE, MACHINING DEVICE, METHOD FOR PRODUCING COMPONENT, METHOD FOR PRODUCING ROLLING BEARING, METHOD FOR PRODUCING VEHICLE, METHOD FOR PRODUCING MACHINE, AND PRESS MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/142654
Kind Code:
A1
Abstract:
A frame structure is provided with: a C-shaped frame in which the front side in a longitudinal direction from among the longitudinal direction, a lateral direction, and a vertical direction that are orthogonal to each other is opened; an upper operation part supported by an upper front-side portion of the C-shaped frame; and a lower operation part supported by a lower front-side portion of the C-shaped frame. When reactive force is applied through the upper operation part, the C-shaped frame deforms such that longitudinal-direction displacement of the upper operation part is cancelled out and rotational displacement of the upper operation part about the axis of the lateral direction is also cancelled out, the displacement being produced in accompaniment with elastic deformation of the upper operation part.
