Therefore, the power failure lamp 105 is fixed to the top plate fixing member 102 by using the long extension member 201. The extension member 201 is, for example, an L-shaped long member, and is fixed to the top plate surrounding the four sides of the top plate 101 with the L-shaped corners arranged along the corners of the top plate 101. It is attached to the member 102. In such an extension member 201, one side of the L-shape is used as a long portion 201a for holding the power failure lamp 105, and the other side is used as a fixing side 201b to the top plate fixing member 102.

The long portion 201a holds the power failure lamp 105 at the L-shaped tip, and in a state where the fixed side 201b is fixed to the top plate fixing member 102, the long portion 201a is perpendicular to the top plate fixing member 102 to which the fixed side 201b is fixed. It is inserted into a narrow space between the top plate fixing member 102 extending to the top plate and the appliance box 106a. In this state, the long portion 201a has a length L1 such that the power failure lamp 105 held at the tip thereof is arranged at a predetermined arrangement position.

On the other hand, the fixing side 201b is provided with a hole through which a bolt for fixing the extension member 201 to the top plate fixing member 102 is passed. The L-shaped length L2 of the fixed side 201b is not limited, but the extension member 201 is short enough to be easily handled between the top plate fixing member 102 and the instrument box 106a. Further, the L-shaped length L2 of the fixed side 201b is a length that facilitates work when the extension member 201 is attached to and removed from the top plate fixing member 102.

<Maintenance method of elevator device>
The difference from the first embodiment in the maintenance of the riding basket 2'with the above configuration is that the extension member 201 is removed from the top plate fixing member 102 when the power failure lamp 105 is maintained and replaced.
