Abstract: A gear device includes a housing, a cover, and a positioning portion. The cover includes a first bearing that receives a first shaft and a second bearing that receives a second shaft. The positioning portion includes a projection that projects from one of the housing or the cover parallel to the first shaft or the second shaft and a fitting hole that is formed in the other one of the housing or the cover to receive the projection. The projection has a length that is set so that when coupling the cover to the housing, in a state in which the first shaft is inserted through the first bearing, the projection enters the fitting hole before the distal end of the second shaft enters the second bearing.

Abstract: According to an embodiment, a vehicle seat sliding device includes a rotary member that integrally rotates with a screw rod, a swinging member that is supported on an upper rail in a manner capable of swinging in a state in which the rotation around a rotational center is restricted and that rotatively supports the rotary member and integrally swings with the rotary member, and receiving members that are fixed to a lower rail and support the swinging member in a manner capable of swinging.

Abstract: A reduction gear includes a housing, a worm, a worm wheel, and a drive gear. The worm is located in the housing and rotates by power of a motor. The worm wheel is moved in cooperation with the worm. The drive gear is moved in cooperation with the worm wheel. The drive gear overlaps the worm. The housing includes a partition wall located between the worm and the drive gear.

Abstract: A power seat slide device includes, for example, a nut member fixed to one of a floor and a seat in a vehicle; a rod screw member that is placed on the other of the floor and the seat in a lengthwise direction of the vehicle, and is to be screwed into the nut member; a screw-through member that is fixed to the other of the floor and the seat, and provided with a through hole through which the rod screw member rotatably passes; a screw fixing member fixed to part of the rod screw member in an axial direction; and a plurality of roll members arranged around the rod screw member in a circumferential direction, to come into sliding contact with the screw-through member and the screw fixing member in the axial direction.

Abstract: According to one embodiment of the present invention, provided is an ionic conductor comprising lithium (Li), borohydride (BH4?), phosphorus (P), and sulfur (S), wherein, in X-ray diffraction (CuK?: ?=1.5405 ?), the ionic conductor has diffraction peaks, at least, at 2?=14.4±1.0 deg, 15.0±1.0 deg, 24.9±1.0 deg, 29.2±1.5 deg, 30.3±1.5 deg, 51.1±2.5 deg and 53.5±2.5 deg.
