Engaging structure of retainer

A retainer adapted to be secured in a mounting hole extending through a mounting plate, comprising:

• a main body comprising an elongated substantially plate-shaped portion and a retaining portion for retaining a member therein;
• and
• an engaging structure extending from the main body and being adapted to engage the mounting hole in the mounting plate, said engaging structure comprising (i) a pair of leg bodies extending from the main body, said leg bodies being substantially parallel to each other and being separated from each other by a gap, each of said leg bodies having a base end and a distal end;
• (ii) a tapered anchor portion connecting distal ends of said leg bodies to each other;
• (iii) pawl pieces projecting from a base end of said anchor portion in a direction such that the pawl pieces diverge from each other, distal ends of said pawl pieces being adapted to elastically abut the back surface of the mounting plate, such that upon application of a force that is directed to pull said anchor portion out of the mounting hole, said pawl pieces are pressed and expanded outwardly so as to plane-contact the back surface of the mounting plate;
• and (iv) urging means projecting from outer surfaces of the leg bodies, said urging means having distal ends adapted to elastically contact the front surface of the mounting plate.

A flexible clamp adapted to be secured in a mounting hole extending through a mounting plate, comprising:

• a main body comprising an elongated and substantially plate-shaped portion and a retaining portion for retaining an elongated member therein, said retaining portion being integrally formed with said elongated and substantially plate-shaped portion;
• and
• an engaging structure extending from the main body and being adapted to engage the mounting hole in the mounting plate, said engaging structure comprising (i) a pair of leg bodies extending from the main body, said leg bodies being substantially parallel to each other and being separated from each other by a gap, each of said leg bodies having a base end and a distal end;
• (ii) a tapered anchor portion connecting distal ends of said leg bodies to each other;
• (iii) pawl pieces projecting from a base end of said anchor portion in a direction such that the pawl pieces diverge from each other, distal ends of said pawl pieces being adapted to elastically abut the back surface of the mounting plate, such that upon application of a force that is directed to pull said anchor portion out of the mounting hole, said pawl pieces are pressed and expanded outwardly so as to plane-contact the back surface of the mounting plate;
• and (iv) elastic plates diagonally projecting from outer surfaces of the leg portions along said base ends, in a direction such that the elastic plates diverge from each other, said elastic plates including intermediate portions that are bent, and distal end portions that extend toward the leg bodies so as to elastically contact the front surface of the mounting plate.
