Support member, support structure, and outer wall structure

A support member for supporting an outer wall surface material in a manner of covering a to-be-attached part from an outdoor side with respect to an outer wall base including:

• a wall base material provided in a manner of surrounding an opening that communicates between an indoor side and the outdoor side and faces the outdoor side, and having a first surface adjacent to the opening and facing the outdoor side and a second surface provided on a side of the first surface opposite to the opening and positioned more to the outdoor side than the first surface;
• and a fitting attached to the wall base material in a manner of covering the opening, and having the to-be-attached part that is attached to the first surface in a state of being overlapped with the first surface from the outdoor side, the support member comprising:
• a support fixing part fixed to the second surface;
• a support extension that extends from the support fixing part to a region opposed to the first surface toward the opening to support the outer wall surface material from the indoor side;
• and
• an end surface support part that extends from the support extension to the outdoor side and has an abutting surface that abuts on one end surface of the outer wall surface material on the opening side to support the one end surface,
• wherein the support extension has a part having a thickness larger than a thickness of the end surface support part as a reference.

• and
• a positioning part that is engaged with a to-be-engaged part provided on the second surface of the wall base material so as to position the support fixing part at the fixing position,
• wherein the positioning part extends from an end of the support fixing part, which is on a side opposite to the end surface support part, to the indoor side.
