Abstract: A power storage device includes a case having a metal lid with an insertion hole, a terminal member inserted through the insertion hole, and a resin member insulating between the case and the terminal member. The lid has a surface facing outside, including a ring-shaped hole-surrounding region around the insertion hole, to which the resin member is airtightly firmly fixed, and an outer region contacting the resin member. A two-region consisting of two, the hole-surrounding region and the outer region, has a two-region length at a two-region length ratio of 3.0 or more, which is the ratio of the maximum two-region length to the minimum two-region length, and a seal length of 1.4 or less, which is the ratio of the maximum seal length to the minimum seal length of the hole-surrounding region.

Abstract: A power storage device includes a case member, a terminal member inserted in an insertion hole of the case member, and a resin member joined to the case member and the terminal member. The resin member includes, on a resin outer surface exposed on an outer side of the case member, at least any one of a recess and a projection portion increasing a creepage distance from a terminal outer surface, which is exposed on the outer side of the case member, of the terminal member to a case outer surface exposed on the outer side of the case member.

Abstract: A method for producing a power storage device includes a process of insert-molding. This process is to relatively move a first mold and a second mold to press a terminal top surface of a terminal member by a top-face close-contact portion of the first mold to a second-mold side and to press a to-be-contacted portion of the terminal member by a contact portion of the second mold to a first-mold side so that a deformed portion of the terminal member is elastically deformed. A resin member is thus insert-molded while the terminal top surface is pressed and tightly contacted with the top-face contact portion.

Abstract: A method for producing a power storage device includes an insert-molding step of making a resin member by insert-molding with respect to a terminal member inserted in an insertion hole of a lid. In this insert-molding step, the insertion hole of the lid is placed in front of a gate, and a molten resin is injected through the gate to flow in an opposite gate-side space in a cavity through the insertion hole, allowing the molten resin to spread over the entire cavity, to form the resin member.

Also described is a knee joint that is of an active type, but comparatively inexpensive. A drive section moves a driven member. An elastic member is arranged between the driven member and a linear motion member. The linear motion member elastically moves in at least one direction, in accordance with movement of the driven member, by way of the elastic member. A crank mechanism can realize bending and extension of the knee joint by converting linear motion of the linear motion member to rotational motion.
