That is, when the note-to-panel 30 is pivoted forward relative to the hinge portion with respect to the back of the chair 2, the locking operation pin (not shown) provided in the locking hole 42 of the tiltable member 20, The second locking operation pin 46 is pushed forward by the second elastic body 48 pushing the second locking operation pin 46 so that the second locking operation pin 46 is engaged with the locking hole 42 of the pivoting member 20 State. That is, when the memo-to-panel 30 is pivotally pulled out from one side of the chair 2 and is extended horizontally, the stopping protrusion 54 of the outer circumferential surface of the stopper 52 engages with the circumferential stopping hole 54 of the fixing supporter 10, The second locking operation pin 46 attached to the fixing supporter 10 is engaged with the locking hole 42 formed in the tiltable member 20 so that the two ends of the memo to panel 30 are held in a horizontally unfolded state. At this time, the second locking support pin 47 is biased by the second elastic body 48 and acts to move forward in the direction of the rear end of the tiltable member 20. The second elastic body 48 is in the form of a coil spring coupled to the outer circumferential surface of the second locking support pin 47. Both end portions of the second elastic body 48 are engaged with the second locking support pin 47, The second locking support pin 47 formed inside the fixing supporter 10 is engaged with the coupling hole so as to advance the second locking support pin 47 in the rear end direction of the pivoting member 20, The locking operation pin 46 provided in the locking hole 42 of the tiltable member 20 is moved in the direction of the rotation of the chair 2 relative to the hinge portion relative to the normal rotation of the panel 30, The second locking operation pin 46 is coupled to the locking hole 42 of the pivoting member 20 while being pushed forward by the second elastic body 48 pushing the second locking operation pin 46.
