Abstract: The fluid pressure actuator of the grasping device 1 is a flexible soft actuator. The fluid pressure actuator is provided offset so as to intersect at least any other fluid pressure actuator on a proximal end portion side of the fluid pressure actuator. A tip portion of one of the fluid pressure actuator approaches a tip portion of the other fluid pressure actuators intersecting on the proximal end portion side when each of the fluid pressure actuators contracts.

Abstract: A fluid pressure actuator used as the grasping device 1 includes a cylindrical tube that expands and contracts under the pressure of a fluid, and a sleeve having a stretchable structure in which fiber cords oriented in a predetermined direction are woven and that covers an outer peripheral surface of the tube. A tip portion of the fluid pressure actuator is provided with a spoon-shape housing portion, and a partition plate that closes an opening surface of the housing portion when the fluid pressure actuator is non-curved or curved.

Abstract: A tire/wheel assembly includes a wheel including a disk and a rim, the wheel having a power reception device attached to an inner peripheral surface of the rim to receive electric power supplied wirelessly from farther outward in a radial direction of the wheel than the rim, and a tire attached so as to cover an outer peripheral surface of the wheel and including a pair of bead portions. Each bead portion in the pair of bead portions includes a bead core and a bead filler, and 0.1≤BFW/BDW≤0.6, where BFW is a width in a tire width direction at a central position of the bead filler in a tire radial direction, and BDW is a maximum width in the tire width direction of the bead core.

Abstract: The fluid pressure actuator comprises an actuator body portion and a sealing mechanism that seals the end of the actuator body portion in the axial direction DAX of the actuator body portion. The sealing mechanism includes a sealing member into which the actuator body portion is inserted, a caulking ring provided on the outer peripheral surface of the actuator body portion inserted into the sealing member and restricting the actuator body portion, and a locking ring that locks the sleeve to the sealing member. The sealing member includes a body portion into which the tube is inserted, and the outer diameter of the body portion is larger than the inner diameter of the tube in the portion not inserted into the body portion.
