Abstract: A sole structure for a shoe includes an upper wall portion disposed on the upper side, a lower wall portion disposed below and away from the upper wall portion, and a sidewall portion that is disposed between the upper wall portion and the lower wall portion and that is elastically deformable in the vertical direction. The upper and lower wall portions and the sidewall portion are formed of resin-made wall-shaped members. A three-dimensional elastic fiber structure formed of resin fibers is provided in the interior region between the upper wall portion and the lower wall portion. The interior region includes a hollow portion that is in contact with the three-dimensional elastic fiber structure via a partition wall formed of a resin-made wall-shaped member.

Abstract: A drive force transmission for a shuttle section in a sewing machine in which a rotation of a spindle is transmitted and transformed into a swing motion to an output shaft coupled with the shuttle section, the drive force transmission comprising: a power transmission mechanism coupled with the spindle; a drive force transmission shaft rotating by the rotation of the spindle through the power transmission mechanism; and a force transforming mechanism provided between the drive force transmission shaft and the output shaft, for transforming the rotation from the drive force transmission shaft into the swing motion of the output shaft.
