  • Patent number: 10696122
    Abstract: An annular reference surface is formed around a through-hole of an eye portion. A distal-end-side curved portion is formed at a first corner portion, on an outer side of the annular reference surface. The thickness of the distal-end-side curved portion is reduced in a range of a length from the first flat surface toward the distal end surface. A hole-side curved portion whose thickness is reduced toward an inner surface of the through-hole is formed at a second corner portion, on an inner side of the annular reference surface. The length of the hole-side curved portion is less than the length of the distal-end-side curved portion. The hole-side curved portion is curved with a greater curvature than that of the distal-end-side curved portion.

  • Publication number: 20200139783
    Abstract: A stabilizer includes bend sections. With respect to positions in a circumferential direction of a radial cross section of each of the bend sections, a center of an inside of a bend is defined as 0°, and a center of an outside of the bend is defined as 180°. The bend sections each include a bend interior section located at 0°, a bend exterior section located at 180°, a first side section located at 90°, and a second side section located at 270°. The bend interior section has compressive residual stress from a surface to a first depth. The bend exterior section has compressive residual stress to a second depth. The first side section has compressive residual stress to a third depth. The second side section has compressive residual stress to a fourth depth.

  • Patent number: 10589590
    Abstract: A stabilizer includes a stabilizer main body, and eyes formed on both ends of the stabilizer main body. Through-holes are formed in fastening surfaces of the eyes, respectively. The stabilizer main body is covered with a main body coating film. The eye is covered with an eye coating film whose thickness is less than a thickness of the main body coating film. An inner surface of the through-hole is covered with an inner surface coating film. An incomplete coating portion is formed at a part of the inner surface of the through-hole in a circumferential direction. The incomplete coating portion is located on an extension of a straight line connecting a center of the through-hole and the center of gravity of the stabilizer main body in a side view of the stabilizer main body.

  • Patent number: 10503173
    Abstract: A moving device includes a transportation mechanism, a detector, and a controller. The transportation mechanism moves from a departure point to a destination point. The detector detects an obstacle existing on a path to the destination point. When the detector detects that the obstacle exists on the path to the destination point, and another path to the destination point does not exist, the controller controls the transportation mechanism to move to a location that does not impede traffic, and stand by.
