Abstract: An exterior member including an exterior main body which covers a whole periphery of a portion of an outer surface of a case main body in a peripheral direction; and fixing projection sections which are formed on predetermined lower edge portions of the exterior main body while projecting toward outer peripheral sides and fix the exterior main body to the case main body by a fixing member attached covering an outer peripheral surface of the case main body.

Abstract: The present disclosure relates to a titanium or titanium alloy member and to a surface hardening method for the titanium or titanium alloy member. The titanium or titanium alloy member includes a base material of titanium or titanium alloy, and at a surface of the base material, a hardened layer formed by diffusion of oxygen into the surface.

Abstract: The present disclosure relates to a titanium or titanium alloy member and to a surface hardening method for the titanium or titanium alloy member. The titanium or titanium alloy member includes a base material of titanium or titanium alloy, and at a surface of the base material, a hardened layer formed by diffusion of oxygen into the surface. The method includes: a heating step of heating the titanium or titanium alloy base material of the member to a predetermined temperature under an inert gas atmosphere; a hardening step of introducing (i) a mixed gas including an inert gas, and (ii) oxygen gas as a hardening treatment gas, to perform hardening treatment of the surface of the base material; and a cooling step of cooling the base material down to room temperature under the inert gas atmosphere.

Abstract: A component mounting member including a base member which is provided with an attachment hole and attached to a case, an attachment member which is inserted into the attachment hole of the base member so as to be attached to an inner surface of the base member located on an inner side of the case, and a terminal which is provided on the attachment member and exposed from the inner surface of the base member and an outer surface opposite to the inner surface.

Abstract: A case including a case body, and an exterior member which is arranged on an outer periphery of the case body in a manner to be deformable in a circumferential direction and which is provided with a separation section for separating at least a part of the case body in the circumferential direction.
