1. A fixing member comprising:
a support column extending in an up-down direction;
elastic locking pieces paired such that the support column is interposed therebetween in a right-left direction and each elastic locking piece extending from connection positions at a support column upper end side toward a support column lower end side; and
a dish-like contact portion radially extending obliquely upward and outward from the support column lower end side so as to surround the support column, wherein
by inserting the support column and the elastic locking pieces into a through hole of a plate-shaped member from the support column upper end side, the elastic locking pieces pass through the through hole with elastic deformation approaching the support column, and when the elastic locking pieces reach a predetermined engagement position, the elastic locking pieces elastically return and project downward from the through hole to lock a surrounding portion of the through hole from a far side in an insertion direction while pressing an inner wall surface of the through hole, and the dish-like contact portion annularly contacts the surrounding portion of the through hole from a near side in the insertion direction, thereby fixing the fixing member to the plate-shaped member,
the dish-like contact portion includes a bent portion which is bent obliquely downward and outward after the dish-like contact portion extends obliquely upward and outward,
the bent portion is independently formed outside of each of the connection positions of the elastic locking pieces with the support column in the right-left direction, and
an upper surface of each bent portion forms a smoothly continuous curved surface around an axis of the support column, and is formed such that a direction from an outer edge of the curved surface when seen in an axial direction of the support column toward a lowest end of the elastic locking piece in a natural state is directed upward.
