Kind Code:

Abstract:
To provide a method by which a step member is surely fastened at the member's position.SOLUTION: A lock member 63 is a component for fastening a step member 30 which is made to go in and out from a housing 20 at the member's position. To the lock member 63, an insertion bar 66 is connected movably in a vertical direction. In a condition that an end 661 of the insertion bar 66 is inserted into a hole 72 for lock, the lock member 63 is kept in a posture (position and sense) for fastening the step member 30 at the member's position. When the lock member 63 is in a posture for not fastening the step member 30 at the member's position, then in the housing 20 is a hole 71 for non-lock into which the end 661 of the insertion bar 66 is inserted. A projection member 80 is between the hole 71 for non-lock and the hole 72 for lock. When the end 661 of the insertion bar 66 touches the projection member 80, the projection member makes the end 661 slide and guides to respective holes (hole 71 and hole 72).SELECTED DRAWING: Figure 9A
