The second pressing member 42 presses the pair of glass holding frames 23 against the panel main portion 21a. By being tightened together, they are fixed to the door panel 21 with the pair of facing portions 21b interposed therebetween.

Thereby, the second panel reinforcement device has the same effect as the first panel reinforcement device 55 .

In the second panel reinforcing device according to Embodiment 2, the second mounting member has a second protrusion projecting toward the second holding member 42, and the second holding member 42 and the second mounting member are tightened together. As a result, the second projecting portion and the second mounting member 42 are pressed together.

Thereby, the second panel reinforcement device has the same effect as the first panel reinforcement device 55 .

In addition, in Embodiments 1 and 2, the panel with the reinforcing device has the first panel reinforcing device 25, the second panel reinforcing device 26, the first panel reinforcing device 55, or the second panel reinforcing device attached to the car door 12. It is. The panel with reinforcing device has the same effect as the first panel reinforcing device 25, the second panel reinforcing device 26, the first panel reinforcing device 55, or the second panel reinforcing device.

In Embodiments 1 and 2, the member to be reinforced is not limited to the glass holding frame 23, and may be, for example, a reinforcing member fixed to the panel main portion 21a. When a member other than the glass holding frame 23 is the member to be reinforced, only the holding member may be replaced with a holding member suitable for the member to be reinforced. As a result, parts other than the pressing member can be shared.

In Embodiments 1 and 2, the first protruding portions 32b may also serve as the pair of first contact portions 32c by being pressed against the pair of glass holding frames 23 . In this case, it is not necessary to provide a pair of first contact portions 32c separately from the first projecting portion 32b. Similarly, in Embodiments 1 and 2, the second protruding portions 42b may also serve as the pair of second contact portions 42c by being pressed against the pair of glass holding frames 23 . In this case, it is not necessary to provide a pair of second contact portions 42c separately from the second projecting portion 42b.

In Embodiments 1 and 2, instead of providing the first pressing member 32 with the first projecting portion 32b and the first contact portion 32c, the first mounting member 31 or the first mounting member 61 is provided with the first projecting portion and the first contact portion 32c. 1 abutment may be provided. Similarly, in Embodiments 1 and 2, instead of providing the second pressing member 42 with the second projecting portion 42b and the second contacting portion 42c, the second mounting member 41 is provided with the second projecting portion and the second contacting portion. may be

In addition, in Embodiments 1 and 2, a pair of opposed portions arranged at intervals in the height direction of the door panel 21 is provided, and the first mounting member 31 or the first mounting member 61 and the first pressing member 32 are provided. may sandwich the pair of facing portions. Similarly, in Embodiments 1 and 2, a pair of opposing portions are provided that are spaced apart from each other in the height direction of the door panel 21, and the second mounting member 41 and the second pressing member 42 are attached to the pair of You may pinch|interpose an opposing part.

In addition, in Embodiment 1, one or more of the first panel reinforcing device 25 and the second panel reinforcing device 26 may be provided on the door panel 21 . Similarly, in Embodiment 2, one or more of the first panel reinforcing device 55 and the second panel reinforcing device may be provided on the door panel 21 .

The elevator panel is not limited to the car door 12, and may be, for example, the landing door 14, the car room wall constituting the car room 11, or the like.
