  By the way, since this conventional passenger-guide light 11 has a small light bulb 14 itself that is somewhat large, the cover 15 that accommodates it is also large, and its thickness (when viewed from the front of the chair) is relatively large. If the elbow provided at the upper end of the leg portion L of the chair C is not widened when attached to the side of the chair C, the chair C will protrude from the elbow width toward the passage side. There has been a problem that the degree of freedom in designing the leg portions of the chair is excessively constrained.

  However, if the passage width necessary for safety of evacuation is secured in a room such as a theater, the remainder becomes the width dimension for installing the chair, so if the elbow width including the passage light is increased, the seating portion inside ( The width of the back and the seat is inevitably narrow, and there is a problem that a comfortable space cannot be secured sufficiently.

  In some cases, a column number display plate P is provided on the side of the chair C serving as a passenger seat facing the aisle. However, such a column number display plate P is conventionally not illuminated and is connected to the seat guide light 11. There is a problem that the visibility is not sufficiently good because it cannot be made too large to avoid interference.

  In order to solve these problems, when an opening is provided in the leg L of the chair C and the passenger seat guide light 11 is to be embedded therein, the seat of the chair C is supported so as to be able to jump up at the normal installation position. Since it interferes with the supporting structure S to be performed, it has to be provided at a high position, and there arises a problem that the illumination light reaching the passage weakens and diffuses too much, which is not preferable.

An object of the present invention is to provide a passage lamp that advantageously solves the above-mentioned problems. The passage lamp of the present invention includes a base plate that can be fixed and an outer side of the base plate that is supported by the base plate.
