[0087] Referring to FIGS. 20 to 22, the coupler (120) may include a center block (126), spring shafts (124, 125), a support wall (121), and side walls (122, 123). The support wall (121) may be formed on the inner surface of the top plate (91). The support wall (121) may form a wall against the top plate (91). The support wall (121) may have support grooves (121a, 121b). The support grooves (121a, 121b) may be formed on the top of the support wall (121). There may be multiple support grooves (121a, 121b). For example, a pair of support grooves (121a, 121b) may be formed on the top of the support wall (121). The support grooves (121a, 121b) may have a shape in which the top of the support wall (121) is cut out.

[0088] The center block (126) may be located between the support grooves (121a, 121b). The center block (126) may be connected to the support wall (121). The side walls (122, 123) may be bent and extended from the support wall (121). There may be multiple side walls (122, 123), and multiple side walls (122, 123) may face each other. For example, a pair of side walls (122, 123) may be bent and extended from both ends of the support wall (121) to face each other. The side walls (122, 123) may include shaft holes (122a, 123a). The shaft holes (122a, 123a) may penetrate the side walls (122, 123). The insert slit (122b, 123b) can connect the upper end of the sidewall (122, 123) from the shaft hole (122a, 123a). The width of the insert slit (122b, 123b) may be smaller than the diameter of the shaft hole (122a, 123a). The sidewall (122, 123) may be referred to as a shaft holder (122, 123).

[0089] Spring shafts (124, 125) may be formed in the center block (126). Spring shafts (124, 125) may be located between the center block (126) and the side walls (122, 123). There may be multiple spring shafts (124, 125), and multiple spring shafts (124, 125) may be formed on both sides of the center block (126). For example, the first spring shaft (124) may be located between one side of the center block (126) and the first side wall (122), and may protrude from one side of the center block (126) and extend toward the first side wall (122). For example, the second spring shaft (125) may be positioned between the other side of the center block (126) and the second side wall (123), and may protrude from the other side of the center block (126) and extend toward the second side wall (123). The spring shafts (124, 125) may be aligned with the shaft holes (122a, 123a).

[0090] The spring shaft (124, 125) may have an elongated cylindrical shape. Side grooves (124a, 125a) may be formed on the outer surface of the spring shaft (124, 125) along the longitudinal direction of the spring shaft (124, 125). There may be multiple side grooves (124a, 125a). For example, a pair of side grooves (124a, 125a) may be formed on both sides of the outer surface of the spring shaft (124, 125). For example, the cross-section of the spring shaft (124, 125) may have an overall 8 shape. The elastic member (129) may be fixed to the spring shaft (124, 125), with one end supported by the support wall (121) and the other end supported by the door cover (110).

[0091] The elastic member (129) may include a coil portion (129a, 129b), a lever portion (129c), and a support portion (129d, 129e). The coil portion (129a, 129b) may be a spirally twisted spring. The coil portion (129a, 129b) may include a first coil portion (129a) and a second coil portion (129b). A first spring shaft (124) may be inserted into the first coil portion (129a).

The inner diameter of the coil portion (129a, 129b) may be smaller than the outer diameter of the spring shaft (124, 125). As the spring shaft (124, 125) is inserted into the coil portion (129a, 129b) by means of the side groove (124a, 125a) of the spring shaft (124, 125), the diameter of the coil portion (129a, 129b) can be extended in one direction. Accordingly, the coil portion (129a, 129b) of the elastic member (129) can be firmly fixed to the spring shaft (124, 125).

[0092] The lever portion (129c) can connect the first coil portion (129a) and the second coil portion (129b). For example, the lever portion (129c) may be U-shaped, and both ends of the lever portion (129c) may be connected to the first coil portion (129a) and the second coil portion (129b), respectively. The support portions (129d, 129e) may include the first support portion (129d) and the second support portion (129e). The first support portion (129e) may be connected to the first coil portion (129a). The second support portion (129d) may be connected to the second coil portion (129b). The support portions (129d, 129e) may be located in the support grooves (121a, 121b). The lever portion (129c) can come into contact with the door cover (110).

[0093]

The flat surface (115d) may form a portion of the shaft (115) of the cylindrical door cover (110). Accordingly, the shaft (115) may be inserted into the shaft hole (122a, 123a, see FIG. 22) through the insert slit (122b, 123b).

[0095] The end of the shaft (115) of the door cover (110) may be spaced apart from the end of the spring shaft (124, 125). The end of the shaft (115) of the first door cover may be spaced a first distance (d1) from the first spring shaft (124). The end of the shaft (115) of the second door cover may be spaced a second distance (d2) from the second spring shaft (125). The first distance (d1) may correspond to the second distance (d2).

[0096] Accordingly, noise may not occur when the door cover (110) rotates. Also, the shaft (115) of the door cover (110) may not cause friction with the elastic member (129) while rotating. Additionally, the ease of assembly of the coupler (120) between the door cover (110) and the top plate (91) may be improved. Furthermore, durability may be improved in response to displacement that occurs as the door cover (110) moves in the longitudinal direction.
