Abstract: A headrest includes a first configuration section comprising a hard urethane and formed with an indentation in a front face, the indentation enabling entry of a supported portion, and the supported portion being a location corresponding to an occipital bone of the head of the seated occupant; and a second configuration section comprising a soft urethane having a lower rigidity than the hard urethane, the second configuration section being provided at the indentation so as to be deformed by the supported portion. Part of the first configuration section, which is a bottom face of the indentation, is configured by a left-right pair of head support faces that support the supported portion and that are connected together at a connection location having a straight line shape. An angle formed between cross-sections of the left and right head support faces when sectioned along a plane perpendicular to the connection location is a first angle that is from 37.2° to 143°. An angle formed between a direction perpendicular to the connection location and a seat front-rear direction when viewed along a seat left-right direction is a second angle that is from 12.8° to 68.7°.

Abstract: A rotor includes a rotor core configured by laminated steel plates and a magnet insertion hole extending along an axial direction of the rotor core, with a resin interposed between a permanent magnet placed in the magnet insertion hole and an inner wall face of the magnet insertion hole. In a manufacturing method for this rotor, in a first process, the permanent magnet and the resin are integrated together to manufacture a resin-coated permanent magnet. Next, in a second process, the resin-coated permanent magnet is press-fitted into the magnet insertion hole. Next, in a third process, the post-second-process rotor core is heated to a temperature that is at least the temperature at which the resin softens. Next, in a fourth process, the post-third process rotor core is cooled.

Abstract: A flexible structure with a multi-joint function is formed by connecting flexing parts in which wave washers are stacked and welded to each other. The flexible structure includes a first flexing part, a second flexing part, and a connection part. The first flexing part and the second flexing part are capable of flexing and extending. The connection part is welded in an axial direction between the first flexing part and the second flexing part and has a rigidity higher than the first flexing part and the second flexing part. The first flexing part and the second flexing part each include wave washers stacked in the axial direction and welded to each other. The connection part has a circulating shape in which an inner circumference and an outer circumference are each continuous in a circumferential direction.
