摘要： A metallic plate that is a structure of a release member, the release member being configured to be integrally rotatable with a reel accommodated in a case, and the release member moving a locking member from a locking position, at which the locking member locks rotation of the reel relative to the case, to an allowing position, at which the locking member allows rotation of the reel. The metallic plate comprises a touching surface that is to be touched by a distal end of a sliding protrusion portion that protrudes from the locking member; and a structure such that, if a plurality of the metallic plate are stacked in a plate thickness direction in a state in which the metallic plates are not attached to release members, the touching surface of each metallic plate is not in contact with any other of the metallic plates.

摘要： The tape reel includes the cylindrical portion and a bottom portion having an installation surface on which the cylindrical portion is installed upright. The installation surface has a central surface located on a center side of the bottom portion, and a first inclined surface formed on an outer peripheral portion of the central surface along a peripheral direction of the cylindrical portion and inclined such that a wall thickness of the bottom portion gradually decreases toward an outer peripheral side. A through hole penetrating the bottom portion is formed in the outer peripheral portion, a pair of wall portions are installed upright on the first inclined surface on both sides of the through hole in the peripheral direction, and a second inclined surface having an inclination angle smaller than an inclination angle of the first inclined surface with respect to the central surface is formed on a surface of each of the wall portions, which is connected to the central surface.
