Abstract: This optical shaping device is provided with: a resin tank; a resin supply part that is provided to one end section of the resin tank and supplies a liquid photocurable resin to the resin tank; and a resin discharge part that is provided to the other end section of the resin tank and discharges the photocurable resin to the resin tank. While a shaped object is formed by irradiation of at least the liquid photocurable resin with laser light beam or a light flux, the resin tank causes the photocurable resin to flow from the one end section toward the other end section.

Abstract: A shaped object shaped by a shaping method includes a structure that is shaped by stacking plural constituent layers and a ceiling wall to support the structure. The structure includes plural spiral form parts. Each spiral form part has a cross section in an elliptic shape and extends in a stacking direction while turning with respect to a center position of the elliptic shape. The plural spiral form parts are disposed in matrix in a state where the center positions are separated from each other by a predetermined distance. The spiral form parts that are adjacently disposed in a row direction and a column direction are shaped so that the turning directions are opposite. In at least one cross section of the structure, the major axes of the spiral form parts that are adjacent in the row direction and the column direction are orthogonal to each other.

Abstract: A finger tool (10) which tightens a fastening member has a housing (11), a force detector (12), a rotary body (15), and a rotation driving mechanism (13). The force detector (12) is arranged on the housing (11) such that, when the housing (11) is attached to a finger (1) of a person's hand, the force detector (12) contacts a finger underside (2) of the finger (1). The rotary body (15) is arranged such that at least a tip thereof is present outside the housing (11), and has a rotation axis parallel to a specified direction. The rotation driving mechanism (13) is housed in the housing (11) and rotates the rotary body (15) around the rotation axis thereof in the state the housing (11) is attached to the finger (1), in response to detection of a force having a component in the specified direction by the force detector (12).
