A slide device including: a fixed rail; a movable rail; a belt-shaped cover member including a coupling plate coupled to the movable rail at an end portion of the belt-shaped cover member, the belt-shaped cover member closing an opening groove of the fixed rail between a longitudinal end portion of the fixed rail and the movable rail; and a slide cover that covers a periphery of a side edge portion of the cover member, wherein the slide cover includes: an upper wall; a lower wall; and a rib disposed along a sliding direction of the movable rail and protruding in a direction toward the side edge portion of the cover member, on at least one of a surface of the upper wall facing the side edge portion of the cover member or a surface of the lower wall facing the side edge portion of the cover member.

Slide device

A joined body includes: a main body section including a wall section forming a passage along which a medium for accelerating heat exchange flows; and a cover configured to cover a surface of the main body section, the cover including: a covering section provided on a side facing the main body section and configured to cover the surface; a groove section provided on the side facing the main body section and configured to accommodate an end portion of the wall section; and a stirred joint section provided on a side opposite to a side where the covering section and the groove section are provided, the stirred joint section being at least partly frictionally stirred by a depth reaching a bottom of the groove section from a surface on a side opposite to the side facing the main body section and bonded to the end portion of the wall section.

Joined body

A seat frame includes: a plate member; and a bar member joined to the plate member, the bar member including a planar portion on at least part of a side surface of the bar member, wherein the plate member and the bar member are joined to each other by a welded portion including a base portion configured to: extend in a longitudinal direction of the bar member; and have a central line positioned closer to a position at which a load from a user is applied upon use of the seat frame than a central portion of the bar member, the central portion being at a center of a length of the bar member, the length being orthogonal to the longitudinal direction of the bar member, the position being in an area of contact between the plate member and the planar portion.

Seat frame

A stabilizer is a stabilizer including: a main body cylinder portion which is elastically deformable and a pair of connection plate portions respectively connected to a pair of left and right suspension devices, wherein the connection plate portion includes a pair of base material portions located on both sides in the connection plate portion in a plate thickness direction T and an alloy oxide region which is disposed between the pair of base material portions and in which alloy oxides are scattered, and wherein crystal grains constituting the pair of base material portions straddle the alloy oxide region in the plate thickness direction and the pair of base material portions are joined.

Stabilizer and method for manufacturing stabilizer

A stabilizer includes a main body cylinder portion which is elastically deformable; and a pair of connection portions respectively connected to a pair of left and right suspension devices. Each of the pair of connection portions is provided with a fixed shaft portion which is solid and fixed to the main body cylinder portion. The fixed shaft portion includes a fitting portion fitted into the main body cylinder portion and a large diameter portion connecting the fitting portion and a connection portion of the pair of connection portions and formed to have a diameter larger than that of the fitting portion.
