Securing fixture for photovoltaic cell module

A securing fixture for a photovoltaic cell module that includes a first frame member that extends in a first direction;

• and a second frame member that extends in a second direction and is adjacent to the first frame member, the second direction being orthogonal to the first direction, the securing fixture being enclosed by the first frame member and the second frame member having a corner portion formed by the first frame member and the second frame member,
• the securing fixture comprising:
• an abutting part that is fixed to a trestle and abuts on the trestle;
• and
• a holding part that holds the photovoltaic cell module, including
• a first protrusion that protrudes in a direction opposite to the abutting part, wherein a gap enclosed by the first frame member and the second frame member is formed inside the first frame member and the second frame member, and the first protrusion abuts on inner side surfaces of the first frame member and the second frame member, the inner side surfaces including the corner portion formed in the gap inside the first frame member and the second frame member, and
• a placing part on which the second frame member is placed.
