Abstract: Provided are a bending structure and a flexible tube for a medical manipulator, which comprise a main body that is composed of the wave washers stacked in an axial direction and kept a stacked state, the main body being bendable according to the expansion and contraction in the axial direction. Accordingly, linearity of load characteristics based on load and a bending angle is made high to make it possible to obtain the flexible tube having superior load bearing and bendability while conducting size reduction.

Abstract: At a vehicle seat, resistance to relative displacement of a passenger in a left-right direction is larger at both left-right direction side portions of a front surface of an upper portion of a backrest than at a left-right direction central portion. Further, a seat cushion has left and right side reinforcing portions that reinforce portions of a cushion pad from outer sides in a left-right direction, and from obliquely lower sides, of front-rear direction central portions of thigh portions of the passenger, and left and right lower surface reinforcing portions that reinforce portions of a lower surface of the cushion pad at outer sides in a left-right direction, and at obliquely lower sides, of buttock portions of the passenger.

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.

Abstract: A pressing structure is arranged between a first pressed body and a second pressed body opposite to the first pressed body and presses the first pressed body and second pressed body. The pressing structure includes a spring member including: a base portion formed of a single strip-like member and having a curved principal surface; two extended portions extending respectively from end portions of the base portion and curved in a form inverse of a curving form of the base portion; and two bent portions extending respectively from end portions of the two extended portions, the end portions being at sides opposite to sides connected to the base portion, the two bent portions being curved in a form inverse of the curving form of the extended portions; and the maximum thickness of the extended portions and bent portions is smaller than the maximum thickness of the base portion.

Abstract: A flexure includes a metal base, a circuit member, and an actuator. The circuit member includes a base insulating layer, a conductor layer, and a cover insulating layer. The conductor layer includes a second pad, and a reference hole, which is an example of a portion to be protected, in a tongue portion. A second end portion of the actuator is fixed to the second pad via an adhesive. The circuit member includes a wall portion. The wall portion is formed between the second pad and the reference hole. A height of the wall portion is greater than a height of the second pad.
