Abstract: A solid electrolyte composition of the present disclosure includes a solvent and an ion conductor including a solid electrolyte, a binder, and a nitrogen-containing organic substance and being dispersed in the solvent. The solid electrolyte includes a sulfide solid electrolyte, the binder includes a styrenic elastomer, and the nitrogen-containing organic substance is represented by the following compositional formula (1). Where, R1 is a chain alkyl group having 7 or more and 21 or less carbon atoms or a chain alkenyl group having 7 or more and 21 or less carbon atoms, R2 is —CH2—, —CO—, or —NH(CH2)3—, and R3 and R4 are each independently a chain alkyl group having 1 or more and 22 or less carbon atoms, a chain alkenyl group having 2 or more and 22 or less carbon atoms, or hydrogen.

Abstract: A solid electrolyte composition of the present disclosure includes a solvent and an ion conductor including a solid electrolyte, a binder, and a nitrogen-containing organic substance and being dispersed in the solvent. The solid electrolyte includes a sulfide solid electrolyte, the binder includes a styrenic elastomer, and the nitrogen-containing organic substance includes at least one selected from the group consisting of primary amines, secondary amines, aminohydroxy compounds, and diamines. The primary amines, the secondary amines, the aminohydroxy compounds, and the diamines each have at least one selected from the group consisting of chain alkyl groups having 8 or more carbon atoms and chain alkenyl groups having 8 or more carbon atoms. The mass proportion of the nitrogen-containing organic substance to the solid electrolyte is 0.30 mass % or more.

Abstract: A power steering device includes: a guide rod (1); a piston (3); a cylinder (2); a transmission mechanism (8, 9, 10) fixed to the cylinder (2), which transmits a steering force by moving integrally with the cylinder (2); a rack shaft (16) provided substantially parallel to the cylinder (2), which moves integrally with the cylinder (2); a pinion (18) provided on an input shaft (23) connected to a steering wheel, the pinion (18) engaging with a rack (25) of the rack shaft (16); and a valve mechanism (24) which causes one of the pressure chambers (4, 5) to communicate with a pressure source and another of the pressure chambers (4, 5) to communicate with a tank in accordance with a rotational load of the pinion (18) in relation to the rack (25).

Abstract: A rack-and-pinion mechanism (21) for changing a direction of wheels in accordance with a steering input, and a power cylinder (20) providing for power assist for operation of the rack-and-pinion mechanism (21) are provided. A rack shaft (9) of the rack-and-pinion mechanism (21) and a piston rod (3) of the power cylinder (20) are placed parallel to each other. The both ends of the rack shaft (9) and the both ends of the piston rod (3) are respectively linked through connecting members (6, 7). The piston rod (3) and the rack shaft (9) are separated from each other, thereby increasing the design flexibility of them.
