Abstract: A vehicle battery unit includes: a battery module where a plurality of battery cells are stacked in a vehicle width direction and a module case for accommodating the battery module. The module case includes: a pair of side plates for holding side surfaces of the battery module; a bottom plate for connecting lower end portions of the pair of side plates to each other; and a pair of end blocks arranged at opposite end portions of the battery module in a stacking direction of the battery module for connecting the pair of side plates to each other. The end block is coupled to an end surface of the side plate in the stacking direction with a coupling bolt, and a thickness of the end block is greater than a thickness of the side plate.

Abstract: A method for preparing decorative lacquered Ti-based articles is disclosed, which method comprises the steps of: (a) heating to 900.degree. to 1300.degree. in vacuum a base of titanium or its alloy whose surface serves as a base material, to grow the crystal grains on the surface of the base while simultaneously thermally etching the surface, so as to make the base surface uneven; (b) cooling the base; (c) etching the surface of the base with an etchant to enlarge the unevenness of the surface; (d) anodizing the base; (e) applying an undercoat onto the surface of the base; (f) optionally heating the undercoat to cure the same; and (g) further applying a coating onto the undercoat and then drying it. The method makes it possible to prepare decorative lacquered Ti-based articles having a Raden-, Hyomon- or Heidatsu, Kyushitsu- or Makie-like appearance utilizing titanium or its alloy as a base material.
