An end portion 38Aa of 38A extends from the connecting bulging portion 38C to the side in the left-right direction and to the front of the opening 40.
The front bulge portion 38A has a connecting side end portion with the connection bulge portion 38C formed wider in the front-rear direction than the other portions, and the right end portion 38Aa of the front bulge portion 38A can wrap around to the front of the opening 40. It is like that.

前記フロアステップ２３は膨出部３８を前後複数本形成することにより、また、後膨出部３８Ｂと前膨出部３８Ａとを連結膨出部３８Ｃで繋ぐことにより、強度向上を図り、開口部４０を形成したことによるフロアステップ２３端部の強度低下を、前膨出部３８Ａの右端部３８Ａａを開口部４０の前方まで回り込ませることにより防いでいる。
フロアステップ２３上にはフロアマット３９が敷設される。このフロアマット３９はフロアステップ２３の周囲だけではなく前後膨出部３８Ａ、３８Ｂ間にも入るリブを下面に形成しており、フロアステップ２３の上面の全面に載置される。 The floor step 23 is formed with a plurality of front and back bulging portions 38, and the rear bulging portion 38B and the front bulging portion 38A are connected by a connecting bulging portion 38C, thereby improving the strength. The lowering of the strength of the end of the floor step 23 due to the formation of 40 is prevented by turning the right end 38Aa of the front bulging portion 38A to the front of the opening 40.
A floor mat 39 is laid on the floor step 23. The floor mat 39 is formed with ribs on the lower surface that enter not only the periphery of the floor step 23 but also between the front and rear bulging portions 38A and 38B, and is placed on the entire upper surface of the floor step 23.
