Abstract: An oil application device includes an oil supply member capable of selectively supplying oil to a first lateral surface and a second lateral surface of a flat wire. The oil supply member includes a first side surface and a second side surface. A part of the first side surface is a first application surface that is in contact with a part of the first lateral surface. Another part of the first side surface is a first non-application surface spaced apart from the first lateral surface. A part of the second side surface is a second application surface that is in contact with a part of the second lateral surface. Another part of the second side surface is a second non-application surface spaced apart from the second lateral surface.

Abstract: A bending apparatus (10) includes an upper first die (11), an upper second die (12), a lower die (13), a control unit (20), an upper first moving mechanism (21), an upper second moving mechanism (22), a lower moving mechanism (23), a holding die (31), and a moving and rotating mechanism (32). The lower die (13) is moved in an upper direction after the upper first die (11) and the upper second die (12) are moved to the front, whereby four coil segments (4) are bent. When the upper second die (12) is moved to a first withdrawal position in the rear direction after the four coil segments (4) are bent, a working space for the holding die (31) is ensured.
