After the position changing member 410 is coupled to the left or right side of the operating member 120, the supporting shaft member 110 or the left and right receiving portions 20 (10 The friction-preventing member 430 may be provided to prevent friction with at least one of the friction-preventing members 430 and 430.

One side edge of the friction preventing member 430 is disposed between the inner surface of the left and right compartments 20 and 10 and either one side of the operation member 120 or the outer side surface of the position change member 410, The flange portion 432 protruding in the circumferential direction may be further provided to prevent rotational friction of the flange portion 432. [

The flange portion 432 is formed in the shape of a circular ring.

On the other hand, when the space between the right storage part 10 and the left storage part 20 is narrow, the position changing part 400 may reduce the space between the inner panel and the outer pannier have.

The first type for the right hand to which the position changing member 410 is applied and the left hand side to which the position changing member 410 is applied because the interval between the right side storage portions 10 is wide, The third type for the right hand in which the position changing member 410 is removed due to the narrow space between the right storage unit 10 and the third type for the right storage unit 40, And the fourth type for the left hand, which is to be deleted.

Thus, it is possible to enhance the utilization of the product and provide convenience in use by using the left and right memo device of the chair according to the embodiment of the present invention.

Hereinafter, functions and effects of the left and right memo device of a chair according to an embodiment of the present invention will be described with reference to the accompanying drawings.

A state in which the table portion 300 is stored and taken out of the right storage portion 10 and used for right-hand use will be described with reference to Figs. 1, 3, 5, 9 and 10.

When the sitting part of the table part 300 is stored in the right side storage part 10 and the occupant seated on the seat tries to use the table part 300 for a memo, the arm part is rotated and turned to rotate the right side storage part 10 Open.

 The operating member 120 of the mounting portion 100 rotates in the rotation hole 30 of the right accommodating portion 10 to be rotatable about the axis of rotation of the table member 300, The table portion 300 is vertically erected together with the elongated member 130 as the tab 130 is vertically erected.

Then, when the table portion 300 is rotated horizontally, the table portion 300 is opened because the rotary member 220 of the support portion 200 is rotated toward the seat side in the seating groove portion 132 of the extending member 130.

When the left and right memo devices of the chair according to the embodiment of the present invention are used for right-handed use and are to be changed for left-handed use, the operation member 120 is inserted into the rotation hole 30 of the left- The position of the position changing member 410 is changed to the outside of the supporting shaft member 110, and is then coupled again using the supporting shaft member 110 and the position fixing unit 420,

Subsequently, in a state in which the friction preventing member 430, the position changing member 410, the actuating member 120, and the friction preventing member 430 are installed in the rotation hole 30 of the left accommodating portion 20 from the outside, After the first supporting shaft member 110 is inserted from the outside and the second supporting shaft member 114 is engaged from the inside to align the positions of the first supporting shaft member 110, And is fastened to the second support shaft member 114 so as to complete the installation of the mounting portion 100.

In this assembly process, only the right and left positions are changed in the right housing part 10, and the same operation is applied. In other words, the supporting portion 100 may be arranged so that only the position changing member 410 is directed outward while the supporting portion 100 is moved as it is, and the supporting portion 20 is rotated after being rotated 180 degrees in a horizontal state. Thus, since only one type of each component is manufactured, only the position of the position-changing member 410 can be changed and the components can be shared, thereby reducing the number of components and significantly lowering the manufacturing cost.

A state in which the table portion 30 is accommodated in the left storage portion 20 and used for left-handed use will be described with reference to Figs. 2, 4, 6, 9, and 10. Fig.

When the seat occupant seated on the seat tries to use the table portion 300 in the state where the table portion 300 is housed in the left storage portion 20, the arm portion is turned and turned so that the left storage portion 20 Open.

 The operating member 120 of the mounting portion 100 is rotated by the rotation hole 30 of the left accommodating portion 20 to be extended from the operating member 120 by the rotation of the table portion 300, The table portion 300 is vertically erected together with the elongated member 130 as the tab 130 is vertically erected.

Then, when the table portion 300 is rotated horizontally, the table portion 300 is opened because the rotary member 220 of the support portion 200 is rotated toward the seat side in the seating groove portion 132 of the extending member 130.

Therefore, the left and right common notepad of the chair according to the present invention can be used as a common part by using the right-hand use table portion and the left-hand use table portion by changing the positions of the left and right sides of the support portion supporting the table portion using the position change portion It is possible to reduce the number of parts and reduce the manufacturing cost.
