To provide a step device for ascending and descending that allows an operator to ascend and descend easily and safely, can suppress deformation or damage even when receiving external force due to interference from the contact with a road surface, has a simple structure and is easily attachable to existing heavy machines.SOLUTION: A step device 10 for ascending and descending includes: a step section 11; a mounting plate 12; and suspension lock sections 13 fixed to the front end side and rear end side of the mounting plate 12, and is attached to a heavy machine and used for ascending and descending to an operator compartment. Under normal conditions, a support shaft 33 and a suspension bracket 32 can rotate around a circular hole in the upper part of the lock hole 44. In the time of ascending and descending, when downward external force is applied to the step section 11, the suspension bracket 32 moves downward, the support shaft 33 enters a long hole part below the lock hole 44 against a compression coil spring 35, and the rotations of the support shaft 33 and the suspension bracket 32 are locked.SELECTED DRAWING: Figure 2

    【課題】運転者が容易かつ安全に昇降でき、路面との接触による干渉による外力を受けても変形や破損を抑制でき、簡単の構造で、既存の重機にも簡単に装着可能な昇降用ステップ装置を実現する。【解決手段】昇降用ステップ装置10は、ステップ部11と、装着板12と、装着板12の前端側及び後端側にそれぞれ固定されて設けられた吊持ロック部13とを備え、重機に装着されて運転室への昇降に供する装置であり、常時は、支持軸33及び吊持用ブラケット32は、ロック孔44の上部の円形孔部を中心に回転可能であり、昇降時に、ステップ部11に下方への外力が加わると、吊持用ブラケット32が下方に移動し、圧縮コイルバネ35に抗して、支持軸33がロック孔44の下の長孔部に入り、支持軸33及び吊持用ブラケット32は、その回転がロックされる。【選択図】図2
