According to the present invention, an operating shaft is rotatably supported on a lower surface of the bracket body through a shaft insertion hole formed in the locking member, and the operation of the locking member is prevented. On the outer peripheral surface of the operation shaft facing the shaft insertion hole, the locking member is rotated by the rotation of the operation shaft so that the locking member is pressed against the urging force of the curtain member.
The bracket is characterized in that it is a bracket for a curtain rail formed with a cam portion that abuts in a direction of retreating to a half-engagement position and a disengagement position where a shallow engagement amount is obtained without applying an urging force to the lever.

[0006]

According to the present invention, when the curtain rail is mounted on the bracket, the front upper edge of the curtain rail is engaged with the rail locking portion of the bracket body, and the curtain is pressed against the urging force applied to the locking member. The rear upper edge of the rail is engaged with and fixed to the rail locking portion of the locking member. If the installation position of the curtain rail is inappropriate, the operation shaft is rotated by a rotation operation tool such as a screwdriver, and the cam portion formed on the operation shaft is brought into contact with the shaft insertion hole of the locking member, and locked. The member is shallow so that no urging force is applied to the curtain rail against the urging force.
To the half-engagement position where the engagement amount is small, the engagement amount between the rail engagement portion of the engagement member and the rear upper edge of the curtain rail is reduced, and the rail engagement portion of the mounting bracket is The amount of engagement with the front upper edge of the curtain rail is made shallow , and its mounting position is adjusted in a state where the urging force on the curtain rail is eliminated .

On the other hand, when removing the curtain rail from the bracket, the operation shaft is rotated by a rotation operation tool such as a screwdriver, and the cam portion formed on the operation shaft comes into contact with the shaft insertion hole of the locking member. The stop member is retracted to the disengaged position against the urging force, the rear upper edge of the curtain rail is dropped from the rail locking portion of the locking member, and the front side of the curtain rail is moved from the rail locking portion of the bracket body. Remove and remove the upper edge.

[0008]

According to this invention, since the operating shaft is rotated by a rotating operation tool such as a driver to release the engagement between the locking member and the curtain rail, the bracket is constructed as in the conventional example. There is no need to forcibly release the engagement between the block body and the curtain rail by a driver or the like, and the cam portion of the operation shaft is rotated in a direction to retract the locking member, thereby preventing the curtain rail from falling off. Even if the necessary biasing force is applied to the locking member, the locking member can be easily retracted simply by rotating the operation shaft, and the curtain rail can be dropped by its own weight without damaging it. Simple
It can simply be removed .

Further, when installing the curtain rail,
Since the engaging member can be retracted to the half-engaged position and the amount of engagement with the curtain rail can be reduced, the curtain rail is in a semi-engaged state without receiving an urging force against the bracket ,
