1. A drain plug fitted to a drain hole formed in a body panel at an end edge part thereof, the body panel being formed of a pair of outside and inside panels, a space between the pair of panels being widened toward a prescribed direction from the end edge part, the drain plug comprising: a head part
1. A drain plug fitted to a drain hole formed in a body panel at an end edge part thereof, the body panel being formed of a pair of outside and inside panels, a space between the pair of panels being widened toward a prescribed direction from the end edge part, the drain plug comprising: a head part arranged on a peripheral edge of the drain hole from a front side, so as to cover the drain hole; andan engaging leg formed on a back surface of the head part, so as to be engaged with the peripheral edge of the drain hole from a back side by being inserted thereinto,wherein the engaging leg includes: a frame wall formed of a front wall and both side walls, so as to be extended in the prescribed direction while being separated from the head part;an opening part provided in a rear part of the frame wall, so as to face the end edge part of the body panel;engaging parts formed on both the side walls, so as to be engaged with the peripheral edge of the drain hole from the back side; anda guide surface formed on the front wall facing the head part, so as to guide the engaging parts to pass through the drain hole, andwherein the head part includes: a thick part having a first thickness;a thin flange part having a second thickness smaller than the first thickness and extending from a peripheral edge of the thick part, so as to elastically abut on the peripheral edge of the drain hole from the front side; andpressing protrusions formed on a back surface of the thick part at positions facing to the engaging parts on the engaging leg, so as to abut on the peripheral edge of the drain hole from the front side. 2. The drain plug of claim 1, wherein the pressing protrusions are formed into ribs extending in a direction perpendicular to the prescribed direction. 3. The drain plug of claim 1, wherein a rib or a recess is formed on a back surface of the thin flange part at an opposite side to the frame wall, so as to form a gap for draining water between the peripheral edge of the drain hole and the thin flange part. 4. A drain plug fitted to a drain hole formed in a body panel at an end edge part thereof, the body panel being formed of a pair of outside and inside panels, a space between the pair of panels being widened toward a prescribed direction from the end edge part, the drain plug comprising: a head part arranged on a peripheral edge of the drain hole from a front side, so as to cover the drain hole; andan engaging leg formed on a back surface of the head part, so as to be engaged with the peripheral edge of the drain hole from a back side by being inserted thereinto,wherein the engaging leg includes: a frame wall formed of a front wall and both side walls, so as to be extended in the prescribed direction while being separated from the head part;an opening part provided in a rear part of the frame wall, so as to face the end edge part of the body panel so as to drain between the head part and the body panel;engaging parts formed on both the side walls, so as to be engaged with the peripheral edge of the drain hole from the back side; anda guide surface formed on the front wall facing the head part, so as to guide the engaging parts to pass through the drain hole. 5. The drain plug of claim 4, wherein a width of the front wall decreases as the front wall extends away from the head part. 6. The drain plug of claim 4, wherein the head part further comprises pressing protrusions formed on a back surface of the head part at positions facing the engaging parts on the engaging leg, so as to abut on the peripheral edge of the drain hole from the front side. 7. The drain plug of claim 4, wherein a distance between the side walls decreases as the side walls extend away from the head part. 8. The drain plug of claim 4, wherein the guide surface is disposed between a distal end of the front wall and the engaging parts. 9. The drain plug of claim 4, wherein the side walls comprise a tapered surface formed along the prescribed direction of the engaging leg. 10. The drain plug of claim 4, wherein the opening part is provided in the rear part of the frame wall opposite the front wall. 11. The drain plug of claim 4, wherein the frame wall comprises a substantially V-shape. 12. The drain plug of claim 4, wherein the engaging parts each includes an engaging surface which engages with the peripheral edge of the drain hole, each engaging surface being continuous with the guide surface. 13. The drain plug of claim 4, wherein a portion of the head part includes a smooth transition between the side walls of the engaging leg to an area of the head part outside of the opening part. 14. The drain plug of claim 4, wherein a portion of the head part extending from inside the engaging leg to outside of the opening part is smooth. 15. The drain plug of claim 4, wherein a side of the head part opposite the engaging leg includes anti-skid protrusions.
