[ Specifically, the first fixed portion 142a of the first disk 142 and the first fixed portion 143a of the second disk 143 may be located below the imaginary line Y, The second fixed portion 142b of the second disk 142 and the second fixed portion 143b of the second disk 143 may be located above the imaginary line Y. [ That is, the first connection shaft 145 may be located below the imaginary line Y, and the second connection shaft 146 may be located above the imaginary line Y. [

5C, when the rack assembly 120 is positioned at the second position, the first fixing portion 142a, the first fixing portion 143a, the second fixing portion 142b, The first disk 143b may be positioned on the virtual line Y connecting the rotational axis 147 of the first disk 142 and the rotational axis 147 of the second disk 143. [ When the rack assembly 120 is in the second position, the second connection shaft 146 may be positioned in front of the first connection shaft 145 in the second direction B.

When the height of the rack assembly 120 changes from the first position to the second position, the rotation guide 140 can rotate in a counterclockwise direction. When the height of the rack assembly 120 changes from the second position to the first position, the rotation guide 140 can rotate clockwise.

6A and 6B are perspective views illustrating a state in which a shelf of an oven is drawn out according to an embodiment of the present invention. Hereinafter, reference numerals not shown in the figures refer to Figs. 1 to 4. Fig.

6A and 6B, the shelf 110 inside the cooking chamber 11 can move toward the second direction B. As shown in Fig.

When the user slides the operating part 125 toward the left side of the cooking chamber 11, the locking part 127 is separated from the fixing hole 128 and the first projection part 132 of the rotation preventing member 131 is inserted into the fixing hole 128). The first area 131a of the rotation preventing member 131 is rotated in the inner direction of the rack guide 123 about the rotating shaft 134 so that the first area 131a is brought into close contact with the outer surface of the rack guide 123 And the second area 131b are spaced apart from the rack guide 123. The second protrusion 133 is inserted into the rotation preventing hole 129a and the rotation of the at least one link 129 and the rotation guide 140 The rotation is constrained. In this state, the shelf 110 can move in the second direction B along with the rail 123a formed on the rack guide 123 integrally with the rack 121.

When the rack 121 is pulled out of the rack guide 123, the first fixing portion 142a, the first fixing portion 143a, the second fixing portion 142b and the second fixing portion 143b are connected to the virtual line Y). &Lt; / RTI >
