Abstract: A vehicle power supply device includes: equipment disposed on an electrical path leading to a DC inlet of an electrified vehicle; and a DC connector disposed on the electrical path. The DC connector includes a first connector attached to a housing of the equipment. The first connector includes a terminal disposed inside the housing and a bus bar fastening portion provided at a tip of the terminal. The equipment includes a bus bar disposed inside the housing and including one end connected to a component of the equipment. The bus bar includes a connector fastening portion fastened to the bus bar fastening portion via a fastener, and a metal Z-shaped spring that expands and contracts in a direction parallel to a stretching direction of the bus bar at the end on the other end side.

Abstract: An assembling structure for an intake manifold includes: a first downstream portion; a second downstream portion; an upstream portion; a connecting member that connects the first downstream portion and the second downstream portion with each other; and a plate-shaped stay. The connecting member is fixed to the first downstream portion and the second downstream portion by a bolt, and an other member that is a member other than the intake manifold is fixed to the intake manifold through the stay at least either between the connecting member and the first downstream portion, or between the connecting member and the second downstream portion.

Abstract: A catalyst including, as effective ingredient, complex represented by Formula (1) which contains bidentate ligand including aromatic heterocyclic 5-membered ring having 2 or more nitrogen atoms, or represented by Formula (2) which contains bidentate ligand including: aromatic heterocyclic 5-membered ring having 2 or more nitrogen atoms; and 6-membered ring having 1 or more nitrogen atoms, isomer or salt of the complex: where M1 and M2 denote transition metal such as iridium; X1 to X16 each independently denote nitrogen or carbon; R1 to R13 denote, for example, hydrogen atom, alkyl group, or hydroxy group, provided that when Xi (where i denotes 13 to 16) is nitrogen, Ri is absent at position corresponding to the nitrogen; L1 and L2 denote, for example, an aromatic anionic ligand; Z1 and Z2 denote any ligand or are absent; and m and n denote positive integer, 0, or negative integer.

Abstract: An intake manifold includes a surge tank, and an intake passage part. An inner surface of the intake passage part includes: an inner peripheral region which is located inner side of the intake passage part in a curvature radius direction; an outer peripheral region which is located outer side of the intake passage part in a curvature radius direction; a first lateral region; and a second lateral region. The outer peripheral region includes a first inclined region, a second inclined region, and a bottom region. When seen in the section orthogonal to a center axis of the intake passage part, the first and second inclined region are curved so as to be convex outward from the intake passage part at a curvature radius. The bottom region has a shape convex outward from the intake passage part in the direction of the curvature radius.
