摘要： On an end portion (20a) of a hollow rod (20), which is a material of a hollow coil spring (10), a terminal sealed portion (30) is formed. The terminal sealed portion (30) has a rotationally symmetric shape in which an axis (X1) passing through the center of the rod (20) is a symmetric axis. The terminal sealed portion (30) includes an end wall portion (41), and a distal-end-center closure portion (43) formed on the axis (X1). In the distal-end-center closure portion (43), a distal end opening portion of the spin-formed rod (20) is joined together and formed as an integral part. On the axis (X1) at the inner surface of the end wall portion (41), a recess (45) having a rotationally symmetric shape in which the axis (X1) is the symmetric axis is formed. A thickness (t) of the recess (45) of the end wall portion (41) is reduced toward the axis (X1) .

摘要： In the coil spring of the present invention, a helical space defined by a space between coils has a first end region whose space is increased as it extends towards the other side in the axial direction from a first reference point where the space is zero, a reference region whose space is set at a reference value L (L> 0), and a second end region whose space becomes narrow as it extends toward the other side in the axial direction and zero at a second reference point. The first end region is configured such that the number of turns of the helical space is greater than 1 and the space between coils in a terminal position is greater than the reference value L. The helical space has a first transitional region between the terminal position of the first end region and the reference region, the first transitional region being configured so that the distance of space between coils is reduced from the terminal position of the first end region along the helical shape of the helical space toward the other side in the axial direction and becomes the reference value L.

摘要： A wire adapted to an elastic member according to the present invention is a wire adapted to an elastic member for manufacturing an elastic member. The wire adapted to an elastic member includes: a core that is made of metal or alloy and is elastically deformable; and an FRP layer configured to cover an outer surface of the core, and including fibers wound around the core, and thermosetting resin provided at least partially to the fibers and fixing the fibers to each other. A winding direction in which the fibers are wound around the core is along a direction of a tensile load out of the tensile load and a compressive load applied to the wire adapted to an elastic member based on a load applied from outside.
