The support member 12 is supported by a series of pressing operations in which the support member 12 is urged to move to the support position A side and the support member 12 is pressed upward on the back surface side of the reflection plate 3 by being movably provided. The reflection plate 3 is moved to the release position B and is moved to the support position A as the movement path of the support member 12 enters the through hole 13, and the reflecting plate 3 is movably placed in the horizontal direction with respect to the support member 12. A supporting portion, which is supported and abuts against the reflection plate 3 supported by the support member 12, to restrict the horizontal movement of the reflection plate 3 is provided separately from the support member 12. [Effect] Even if the horizontal position of the reflection plate is not regulated by the support member and the relative position of the support position by the support member with respect to the instrument body side is deviated, the reflection plate is not easily distorted. The reflector can be supported on the instrument body side.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention provides a support position in which each of a plurality of supporting members entering the lower surface side through a through hole formed in the reflecting plate enters the lower surface side of the reflecting plate, and a supporting release position separating from the lower surface side of the reflecting plate. And a biasing member that biases each of the support members toward the support position, the support being moved toward the support position. By a series of pressing operations of pressing the member upward on the back surface side of the reflection plate, the supporting member moves to the supporting releasing position against the urging force, and the moving path of the supporting member is the through hole. The present invention relates to a lighting fixture in which the support member moves to the support position as it enters, and the reflector is supported on the fixture body side.

[0002]

[Prior art]

 Although the lighting fixture can be easily attached to the main body of the lighting fixture by a series of pressing operations that push the support member upward on the back side of the reflector without operating the support member of the reflector in advance. In conventional lighting fixtures, a support member that supports the reflector is provided integrally with the tip of the leaf spring that is fixed to the fixture body side, and the elastic force of the leaf spring moves the support member toward the supporting position. The supporting plate is mounted and supported by the supporting member, and the urging force of the plate spring presses the peripheral edge of the through hole of the reflecting plate to support the vertical and horizontal movements of the reflecting plate. The reflector is supported on the instrument body side in a state where the members are individually regulated (for example, see Japanese Utility Model Publication No. 3-10567).

[0003]

[Problems to be solved by the device]

 For this reason, if the leaf spring is fixed in a posture different from the predetermined posture with respect to the instrument body side due to distortion of the fixing member that fixes the leaf spring, shape error of the leaf spring, etc., The relative position of the support position with respect to the instrument body side is distorted, and each support member individually restricts the vertical and horizontal movements of the reflection plate, and supports the reflection plate at the support position. Therefore, there is a drawback in that the reflector is distorted such as twisted or bent depending on the degree of the deviation. The present invention has been made in view of the above circumstances, and by devising the support structure by the support member, even if the relative position of the support position of the support member with respect to the instrument body side is distorted, the reflector plate is distorted. The purpose is to make it possible to support the reflector on the side of the main body of the equipment in a state where it is unlikely to occur.

[0004]

[Means for Solving the Problems]

 A characteristic configuration of the present invention for achieving the above object is a lighting fixture as described above, wherein the reflection plate is mounted and supported so as to be movable in a horizontal direction with respect to the support member, and is mounted on the support member. A restriction part that restricts the horizontal movement of the reflection plate by contact with the supported reflection plate is provided separately from the support member.

[0005]

[Action]

 The reflector is placed and supported movably along the horizontal direction with respect to the support member, and the restriction unit provided separately from the support member restricts the horizontal movement of the reflector, so that the support position of the support member is used. Even if the relative position of the device with respect to the main body of the device is deviated, in each supporting member, the reflection plate is supported in a state of being displaced from the support member by an amount corresponding to the deviation.

[0006]

[Effect of device]

 Therefore, the horizontal position of the reflector is not restricted by the support member, and even if the relative position of the support position by the support member with respect to the instrument body side is distorted, the reflector is not easily distorted and The plate can be supported on the instrument body side.
