The first duct (100) can be arranged to be undocked from the second duct (200) by moving approximately along the second direction (D2). For example, the first duct (100) can be undocked from the second duct (200) by moving approximately forward (in the +X direction).

The flange (113) may be configured to be coupleable to the second duct (200). Specifically, the flange (113) of the first duct (100) may be arranged to be docked and undocked with the flange (213) of the second duct (200). For example, the flange (113) may extend rearward from a portion of the duct body (111). For example, the flange (113) may include a hollow shape. For purposes of distinction between the configurations, the flange (113) of the first duct (100) may be referred to as the first flange (113), and the flange (213) of the second duct (200) may be referred to as the second flange (213).

[0111] The first duct (100) may include an inlet (120). The inlet (120) may be provided to receive water. The inlet (120) may be formed in the duct frame (110) to allow water to flow into the flow path (110f). The inlet (120) may be formed in the flange (113). Water flowing out from the second duct (200) may flow into the flow path (110f) through the inlet (120). While the first duct (100) and the second duct (200) are coupled to each other, the inlet (120) of the first duct (100) may be in communication with the outlet (230) of the second duct (200). For example, the inlet (120) may be opened rearward (in the -X direction).

[0112] The first duct (100) may include an outlet (130). The outlet (130) may be configured to discharge water. The outlet (130) may be formed in the duct frame (110) so that water may flow out from the flow path (110f). Water in the flow path (110f) may flow to the spray rotor (500) through the outlet (130). While the first duct (100) and the spray rotor (500) are coupled to each other, the outlet (130) may be in communication with the interior of the spray rotor (500). For example, the outlet (130) may be opened downward (in the -Z direction).

[0113] For example, a plurality of outlets (130) may be provided. The plurality of outlets (130) may be spaced apart along the direction of water flow. The plurality of outlets (130) may be spaced apart along the second direction (D2). The plurality of outlets (130) may be arranged along the second direction (D2).

However, the present disclosure is not limited to the above-described examples, and there is no limitation on the number of outlets (130).

[0114] The first duct (100) may include a first holder (170). The first holder (170) may include an outlet (130). The first holder (170) may form the outlet (130). The first holder (170) may be arranged to surround the outlet (130). The first holder (170) may be formed at the lower portion of the duct frame (110). The first holder (170) may extend downward from the duct frame (110). The first holder (170) may rotatably support the upper portion of the spray rotor (500). The upper portion of the spray rotor (500) may be rotatably coupled to the first holder (170).

[0115] The first duct (100) may include a second holder (180). The second holder (180) may be spaced apart from the first holder (170). The second holder (180) may be formed at the lower portion of the duct frame (110). The second holder (180) may extend downward from the duct frame (110). The second holder (180) may rotatably support the lower portion of the spray rotor (500). The lower portion of the spray rotor (500) may be rotatably coupled to the second holder (150).

[0116] The first duct (100) may include a hook (140). The hook (140) may be formed on the duct frame (110). For example, the hook (140) may be formed on the lower portion of the duct frame (110). For example, the hook (140) may extend from the duct body (111). While the first duct (100) is coupled to the basket (53), the hook (140) may correspond to the first wire (531).

[0117] A detailed description of the hook (140) will be provided later.

[0118] The first duct (100) may include an elastic rib (150). The elastic rib (150) may be formed on the duct frame (110). For example, the elastic rib (150) may be formed on the lower portion of the duct frame (110). For example, the elastic rib (150) may extend from the duct body (111). The elastic rib (150) may be spaced apart from the hook (140) in the second direction (D2). While the first duct (100) is coupled to the basket (53), the elastic rib (150) may correspond to the first wire (531).

[0119] A detailed description of the elastic rib (150) will be provided later.

[0120] The first duct (100) may include a support rib (160). The support rib (160) may be formed on the duct frame (110). For example, the support rib (160) may be formed on the lower portion of the duct frame (110). For example, the support rib (160) may extend from the duct body (111). The support rib (160) may be spaced apart from the hook (140) in the second direction (D2). The support rib (160) may be spaced apart from the elastic rib (150) in the second direction (D2). While the first duct (100) is coupled to the basket (53), the support rib (160) may correspond to other wires (532 and / or 533) other than the first wire (531).

[0121] For example, the first duct (100) may include a plurality of support ribs (160), and the plurality of support ribs (160) may be arranged along the second direction (D2). For example, the hook (140) and the elastic rib (150) may be arranged between two of the plurality of support ribs (160).

[0122] For example, the first duct (100) may include a first support rib (160a) and a second support rib (160b). The hook (140) and the elastic rib (150) may be arranged between the first support rib (160a) and the second support rib (160b). However, the present disclosure is not limited to the above-described example, and there is no limitation on the number of support ribs (160). However, for the convenience of explanation, the following description will focus on an example in which the first duct (100) includes two support ribs (160a, 160b).

[0123] The first support rib (160a) may be positioned behind the hook (140). The first support rib (160a) may be positioned behind the elastic rib (150). While the first duct (100) is coupled to the basket (53), the first support rib (160a) may correspond to the second wire (532).

[0124] The second support rib (160b) may be positioned in front of the hook (140). The second support rib (160b) may be positioned in front of the elastic rib (150). While the first duct (100) is coupled to the basket (53), the second support rib (160b) may correspond to the third wire (533).

[0125] A detailed description of the support rib (160) will be provided later.

[0126] The spray rotor (500) may be configured to be detachably mounted on the first duct (100). While the spray rotor (500) is mounted on the first duct (100), the spray rotor (500) may be configured to receive water flowing out of the first duct (100) and spray the supplied water toward the dishes.

[0127] The injection rotor (500) may include a communication port (510). The communication port (510) may be opened toward the outlet (130). The communication port (510) may receive water flowing out from the outlet (130). The water flowing out from the outlet (130) may flow into the injection rotor (500) through the communication port (510). For example, the communication port (510) may be opened upward (in the +Z direction).

[0128] The spray rotor (500) may include a spray port (520). The spray port (520) may discharge water inside the spray rotor (500). While the spray rotor (500) rotates with respect to the first duct (100), the spray port (520) of the spray rotor (500) may spray water toward the dishes.

[0129] Next, the flow of water will be described by way of example. The first duct (100) can guide water. The water can flow in approximately the second direction (D2) in the flow path (110f). The water flowing in the flow path (110f) can flow out from the first duct (100) through a plurality of outlets (130). The water flowing out through the plurality of outlets (130) can flow to a plurality of spray rotors (500). Each of the communication ports (510) of the spray rotors (500) can receive water flowing out through each of the outlets (130). Each of the spray ports (520) of the spray rotors (500) can spray the water supplied from the first duct (100) toward the dishes.

[0130] Fig. 11 is an enlarged view of portion A shown in Fig. 6 according to one embodiment of the present disclosure. Fig. 12 is a cross-sectional view taken along line II-II' shown in Fig. 11 according to one embodiment of the present disclosure. Fig. 13 illustrates an embodiment in which the positions of the hook and elastic rib shown in Fig. 12 are changed according to one embodiment of the present disclosure.

[0131] The hook (140) may be configured to hold the first wire (531) while the first duct (100) is coupled to the basket (53). The hook (140) may be in contact with the first wire (531) while the first duct (100) is coupled to the basket (53). The hook (140) may be configured to limit movement of the first duct (100) relative to the basket (53) while the first duct (100) is coupled to the basket (53).

[0132] For example, the hook (140) may include a hook body (141) and a hook protrusion (142). The hook body (141) may extend from the lower portion of the duct frame (110). The hook body (141) may include a shape that is inclined approximately along the second direction (D2). The hook protrusion (142) may extend from the hook body (141) and include a shape corresponding to the first wire (531). The hook protrusion (142) may be provided to wrap a portion of the first wire (531). The hook protrusion (142) may be formed at an end of the hook body (141). However, the present disclosure is not limited to the above-described examples, and the hook (140) may include various shapes to hold the first wire (531).

[0133] For example, a first gap (g1) may be formed between the duct frame (110) and the hook (140). The hook (140) may be configured to be elastically deformable and may move approximately in a third direction (D3) (e.g., vertical direction (Z direction)) by the first gap (g1). For example, a portion of the hook body (141) and the hook protrusion (142) may move upward. For example, the hook (140) may move until the hook protrusion (142) touches the duct frame (110).

[0134] The elastic rib (150) may be configured to elastically support the first wire (531) while the first duct (100) is coupled to the basket (53). The elastic rib (150) may be in contact with the first wire (531) while the first duct (100) is coupled to the basket (53). The elastic rib (150) may be configured to restrict movement of the first duct (100) relative to the basket (53) in a direction opposite to the direction in which the hook (140) restricts movement of the first duct (100) relative to the basket (53) while the first duct (100) is coupled to the basket (53). That is, the direction in which the hook (140) restricts movement of the first duct (100) with respect to the basket (53) and the direction in which the elastic rib (150) restricts movement of the first duct (100) with respect to the basket (53) may be opposite to each other. Accordingly, while the first duct (100) and the basket (53) are coupled to each other, the first duct (100) may not be easily separated from the basket (53) or easily disengaged from the position in which it is coupled to the basket (53).

[0135] For example, the elastic rib (150) may include a first rib body (151) and a second rib body (152). The first rib body (151) may extend downward from the duct frame (110). The second rib body (152) may extend upward from the first rib body (151). The second rib body (152) may extend from the lower end of the first rib body (151). As an example, the elastic rib (150) may include an approximately 'V' shape. However, the present disclosure is not limited to the above-described examples, and the support rib (150) may include various shapes so as to elastically support the first wire (531).

[0136] For example, a second gap (g2) may be formed between the first rib body (151) and the second rib body (152). The second gap (g2) may include a shape that tapers downward. The elastic rib (150) may include an elastically deformable material and may move approximately along the second direction (D2) (e.g., the front-back direction (X direction)) by the second gap (g2).

[0137] Referring to FIGS. 11 to 13, while the first duct (100) is coupled to the basket (53), the hook (140) and the elastic rib (150) can secure the first wire (531). The hook (140) and the elastic rib (150) can be arranged so that the first wire (531) is placed between the hook (140) and the elastic rib (150). That is, the first wire (531) can be arranged between the hook (140) and the elastic rib (150). Each of the hook (140) and the elastic rib (150) can contact the first wire (531) arranged between the hook (140) and the elastic rib (150). The first wire (531) can interfere with the hook (140). The first wire (531) can interfere with the elastic rib (150). Accordingly, the hook (140) and the elastic rib (150) can be configured to hold the first wire (531) approximately in the second direction (D2). For example, the hook (140) and the elastic rib (150) can be configured to hold the first wire (531) forward and backward. The first wire (531) can be restricted from moving in the second direction (D2) with respect to the first duct (100). The first wire (531) may not be easily detached or separated from the first duct (100). Consequently, the bonding force between the basket (53) and the first duct (100) can be increased.

[0138] According to one embodiment of the present disclosure, the elastic rib (150) may be configured to be elastically deformable along the second direction (D2). For example, the second rib body (152) may be bent approximately along the second direction (D2) (see the dashed lines in FIGS. 12 and 13). As a result, the elastic rib (150) may elastically support the first wire (531).

[0139] For example, an impact may occur when the basket (53) is pulled out and / or pulled in. Specifically, an impact may occur due to friction between the first duct (100) and the second duct (200) while the first duct (100) is docked to the second duct (200) and / or while the first duct (100) is undocking from the second duct (200). If the first duct (100) does not properly secure the basket (53), the first duct (100) and the basket (53) may shake due to the impact, and the bonding strength between the duct (100) and the basket (53) may deteriorate. In addition, dishes stored in the basket (53) may be damaged due to the impact. However, according to the present disclosure, the elastic rib (150) may be provided to attenuate / reduce shock, vibration, etc. applied to the first wire (531) by elastically supporting the first wire (531). The elastic rib (150) may attenuate shock generated when the basket (53) is pulled out and / or pulled in. The elastic rib (150) may reduce shock generated when the first duct (100) is docked to the second duct (200) or undocking from the second duct (200). As a result, the bonding force between the first duct (100) and the basket (53) may be increased, and the dishes may be stably supported by the basket (53).

[0140] For example, referring to FIG. 12, the hook (140) may be configured to contact the front portion (531a) of the first wire (531), and the elastic rib (150) may be configured to contact the rear portion (531b) of the first wire (531). Here, the front portion (531a) of the first wire (531) may refer to the front portion with respect to the center (C) of the first wire (531), and the rear portion (531b) of the first wire (531) may refer to the rear portion with respect to the center (C) of the first wire (531). While the hook (140) holds the front portion (531a) of the first wire (531), the elastic rib (150) may elastically support the rear portion (531b) of the first wire (531). For example, the hook projection (142) of the hook (140) can wrap around the front portion (531a) of the first wire (531). For example, the second rib body (152) of the elastic rib (150) can come into contact with the rear portion of the first wire (531).

[0141] The embodiment illustrated in FIG. 13 may be substantially the same as the embodiment illustrated in FIG. 12, except that the positions of the hook (140) and the elastic rib (150) are swapped. For example, referring to FIG. 13, the hook (140) may be configured to contact the rear portion (531b) of the first wire (531), and the elastic rib (150) may be configured to contact the front portion (531a) of the first wire (531). While the hook (140) catches the rear portion (531b) of the first wire (531), the elastic rib (150) may elastically support the front portion (531a) of the first wire (531). For example, the hook protrusion (142) of the hook (140) may wrap around the rear portion (531b) of the first wire (531). For example, the second rib body (152) of the elastic rib (150) can contact the rear portion of the first wire (531).

[0142] Fig. 14 is an enlarged view of portion B shown in Fig. 6 according to one embodiment of the present disclosure. Fig. 15 is a cross-sectional view taken along line Ⅲ-Ⅲ' shown in Fig. 14 according to one embodiment of the present disclosure. Fig. 16 is a cross-sectional view taken along line Ⅳ-Ⅳ' shown in Fig. 14 according to one embodiment of the present disclosure.

[0143] Referring to FIGS. 14 to 16, the first support rib (160a) may be provided to support the second wire (532) while the first duct (100) is coupled to the basket (53). The first support rib (160a) may be provided to hold the second wire (532) while the first duct (100) is coupled to the basket (53). The first support rib (160a) may be configured to contact the second wire (532) while the first duct (100) is coupled to the basket (53).

[0144] The first support rib (160a) may be in contact with the second wire (532) to restrict the second wire (532) from moving in a third direction (D3) (e.g., vertical direction (Z direction)) with respect to the first duct (100) while the first duct (100) is coupled to the basket (53). The first support rib (160a) may be configured to hold the second wire (532) approximately in the third direction (D3). As a result, the first support rib (160a) may prevent / reduce the second wire (532) from shaking along the third direction (D3). The second wire (532) may not be easily detached or separated from the first duct (100). The coupling strength between the basket (53) and the first duct (100) may be increased.

[0145] For example, the first support rib (160a) may include a first support portion (161a). The first support portion (161a) may be formed at the lower portion of the first duct (100). The first support portion (161a) may be formed at the lower portion of the duct frame (110). The first support portion (161a) may be provided to hold the upper portion of the second wire (532).

[0146] For example, the first support rib (160a) may include a second support portion (162a). The second support portion (162a) may be spaced downward from the first support portion (161a) to hold the lower portion of the second wire (532).

[0147] For example, the first support rib (160a) may include a first connecting portion (163a). The first connecting portion (163a) may connect the first support portion (161a) and the second support portion (162a). The first connecting portion (163a) may extend approximately along the third direction (D3).

[0148] For example, the first support rib (160a) may include a first groove (164a). The first groove (164a) may be defined by a first support (161a), a second support (162a), and a first connection (163a). The first groove (164a) may be formed by the first support (161a), the second support (162a), and the first connection (163a). The first groove (164a) may be configured to receive a second wire (532). The second wire (532) may be configured to be insertable into the first groove (164a). For example, the first groove (164a) may be open toward the front.

[0149] For example, the second wire (532) disposed in the first groove (164a) may interfere with each of the first support (161a) and the second support (162a). The second wire (532) disposed in the first groove (164a) may be restricted from moving upward by the first support (161a). The second wire (532) disposed in the first groove (164a) may be restricted from moving downward by the second support (162a).

[0150] As the examples described above, the second wire (532) may be restricted from moving in the third direction (D3) with respect to the first duct (100). The first support rib (160a) may effectively secure the second wire (532).

[0151] The first support rib (160a) may be in contact with the second wire (532) to restrict the second wire (532) from moving in a first direction (D1) (e.g., left-right direction (Y direction)) with respect to the first duct (100) while the first duct (100) is coupled to the basket (53). As a result, the first support rib (160a) may prevent / reduce the second wire (532) from swinging along the first direction (D1). The second wire (532) may not be easily detached or separated from the first duct (100). The coupling strength between the basket (53) and the first duct (100) may be increased.

[0152] For example, the second wire (532) may include a first extension portion (5321) extending along the first direction (D1), a second extension portion (5322) bent downward from one side of the first extension portion (5321), and a third extension portion (5323) bent downward from the other side of the first extension portion (5321). For example, the second wire (532) may include a shape roughly resembling a 'U' turned upside down.

[0153] For example, while the first duct (100) is coupled to the basket (53), the second support portion (162a) of the first support rib (160a) may be configured to contact the second extension portion (5322) and the third extension portion (5323). One side (1621a) of the first support rib (160a) may interfere with the second extension portion (5322). One side (1621a) of the first support rib (160a) may contact the second extension portion (5322). The other side (1622a) of the first support rib (160a) may interfere with the third extension portion (5323). The other side (1622a) of the first support rib (160a) may contact the third extension portion (5323). For example, the length (L1) of the second support portion (162a) along the first direction (D1) may be set to correspond, within a predetermined error range, to the length along the first direction (D1) between the second extension portion (5322) and the third extension portion (5323). Here, the length along the first direction (D1) between the second extension portion (5322) and the third extension portion (5323) may mean the minimum length between the second extension portion (5322) and the third extension portion (5323). For example, the length (L1) of the second support portion (162a) along the first direction (D1) may be set to correspond, within a predetermined error range, to the length of the first extension portion (5321) along the first direction (D1).

[0154] As the examples described above, the second wire (532) may be restricted from moving in the first direction (D1) with respect to the first duct (100). The first support rib (160a) may effectively secure the second wire (532).

[0155] Fig. 17 is an enlarged view of portion C shown in Fig. 6 according to one embodiment of the present disclosure. Fig. 18 is a cross-sectional view taken along line Ⅴ-Ⅴ' shown in Fig. 17 according to one embodiment of the present disclosure. Fig. 19 is a cross-sectional view taken along line Ⅵ-Ⅵ' shown in Fig. 17 according to one embodiment of the present disclosure.

[0156] Referring to FIGS. 17 to 19, the second support rib (160b) may be provided to support the third wire (533) while the first duct (100) is coupled to the basket (53). The second support rib (160b) may be provided to hold the third wire (533) while the first duct (100) is coupled to the basket (53). The second support rib (160b) may be configured to contact the third wire (533) while the first duct (100) is coupled to the basket (53).

[0157] The second support rib (160b) may be in contact with the third wire (533) to restrict the third wire (533) from moving in a third direction (D3) (e.g., vertical direction (Z direction)) with respect to the first duct (100) while the first duct (100) is coupled to the basket (53). The second support rib (160b) may be configured to hold the third wire (533) approximately in the third direction (D3). As a result, the second support rib (160b) may prevent / reduce the third wire (533) from shaking along the third direction (D3). The third wire (533) may not be easily detached or separated from the first duct (100). The coupling strength between the basket (53) and the first duct (100) may be increased.

[0158] For example, the second support rib (160b) may include a third support portion (161b). The third support portion (161b) may be formed at the lower portion of the first duct (100). The third support portion (161b) may be formed at the lower portion of the duct frame (110). The third support portion (161b) may be provided to hold the upper portion of the third wire (533).

[0159] For example, the second support rib (160b) may include a fourth support portion (162b). The fourth support portion (162b) may be spaced downward from the third support portion (161b) to hold the lower portion of the third wire (533).

[0160] For example, the second support rib (160b) may include a second connecting portion (163b). The second connecting portion (163b) may connect the third supporting portion (161b) and the fourth supporting portion (162b). The second connecting portion (163b) may extend approximately along the third direction (D3).

[0161] For example, the second support rib (160b) may include a second groove (164b). The second groove (164b) may be defined by a third support (161b), a fourth support (162b), and a second connection (163b). The second groove (164b) may be formed by the third support (161b), the fourth support (162b), and the second connection (163b). The second groove (164b) may be configured to accommodate a third wire (533). The third wire (533) may be configured to be insertable into the second groove (164b). For example, the second groove (164b) may be open toward the front.

[0162] For example, the third wire (533) arranged in the second groove (164b) may interfere with each of the third support (161b) and the fourth support (162b). The third wire (533) arranged in the second groove (164b) may be restricted from moving upward by the third support (161b). The third wire (533) arranged in the second groove (164b) may be restricted from moving downward by the fourth support (162b).

[0163] As the examples described above, the third wire (533) may be restricted from moving in the third direction (D3) with respect to the first duct (100). The second support rib (160b) may effectively secure the third wire (533).

[0164] The second support rib (160b) may be in contact with the third wire (533) to restrict the third wire (533) from moving in the first direction (D1) (e.g., left-right direction (Y direction)) with respect to the first duct (100) while the first duct (100) is coupled to the basket (53). As a result, the second support rib (160b) may prevent / reduce the third wire (533) from swinging along the first direction (D1). The third wire (533) may not be easily detached or separated from the first duct (100). The coupling strength between the basket (53) and the first duct (100) may be increased.

[0165] For example, the third wire (533) may include a fourth extension portion (5331) extending along the first direction (D1), a fifth extension portion (5332) bent downward from one side of the fourth extension portion (5331), and a sixth extension portion (5333) bent downward from the other side of the fourth extension portion (5331). For example, the third wire (533) may include a shape roughly resembling a 'U' turned upside down.

[0166] For example, while the first duct (100) is coupled to the basket (53), the fourth support portion (162b) of the second support rib (160b) may be configured to contact the fifth extension portion (5332) and the sixth extension portion (5333). One side (1621b) of the second support rib (160b) may interfere with the fifth extension portion (5332). One side (1621b) of the second support rib (160b) may contact the fifth extension portion (5332). The other side (1622b) of the second support rib (160b) may interfere with the sixth extension portion (5333). The other side (1622b) of the second support rib (160b) may contact the sixth extension portion (5333). For example, the length (L2) of the fourth support portion (162b) along the first direction (D1) may be set to correspond to the length along the first direction (D1) between the fifth extension portion (5332) and the sixth extension portion (5333) within a predetermined error range. Here, the length along the first direction (D1) between the fifth extension portion (5332) and the sixth extension portion (5333) may mean the minimum length between the fifth extension portion (5332) and the sixth extension portion (5333). For example, the length (L1) of the fourth support portion (162b) along the first direction (D1) may be set to correspond to the length of the fourth extension portion (5331) along the first direction (D1) within a predetermined error range.

[0167] As the examples described above, the third wire (533) may be restricted from moving in the first direction (D1) with respect to the first duct (100). The second support rib (160b) may effectively secure the third wire (533).

[0168] FIG. 20 schematically illustrates a state in which a hook of a duct is pressed according to one embodiment of the present disclosure. FIG. 21 schematically illustrates a state in which a duct is moved relative to a basket after a hook of the duct is pressed according to one embodiment of the present disclosure.

[0169] Meanwhile, in FIGS. 20 and 21, only the second support rib (160b) among the plurality of support ribs (160) is illustrated, but the contents illustrated for the second support rib (160b) can be equally applied to the first support rib (160a).

[0170] The first duct (100) can be coupled to or separated from the basket (53) by moving in the second direction (D2) with respect to the basket (53).

[0171] For example, referring to FIGS. 20 and 21, a process of separating the first duct (100) from the basket (53) will be described. Referring to FIG. 20, the hook (140) of the first duct (100) can be pressed. For example, a user can press the hook (140) using the user's hand or a tool. As the hook (140) is pressed, the hook (140) can be elastically deformed. Referring to FIG. 21, after the hook (140) of the first duct (100) is pressed, the first duct (100) can move approximately in the second direction (D2) with respect to the basket (53). For example, the first duct (100) can move backward (in the -X direction). The first wire (531) can come out from between the hook (140) and the elastic rib (150). Accordingly, the hook (140) and the elastic rib (150) may not fix the first wire (531). In addition, the support rib (160) may not support at least one wire (532 and / or 533) of the basket (53). For example, the second wire (532) may come out from the first groove (164a) of the first support rib (160a). For example, the third wire (533) may come out from the second groove (164b) of the second support rib (160b). Consequently, as the first duct (100) moves in the second direction (D2) with respect to the basket (53), the first duct (100) and the basket (53) may be easily separated.

[0172] For example, a process in which a first duct (100) is coupled to a basket (53) will be described. The first duct (100) can move in approximately a second direction (D2) with respect to the basket (53). For example, the first duct (100) can move forward (in the +X direction) (the first duct (100) moves forward in the state illustrated in FIG. 21). While the first duct (100) moves, the hook (140) can be elastically deformed by being pressed by the first wire (531). After the first duct (100) moves, the pressed hook (140) can be restored to its original state, and the first wire (531) can be placed between the hook (140) and the elastic rib (150). As a result, the first wire (531) can be fixed by the hook (140) and the elastic rib (150). Additionally, the support rib (160) can support at least one wire (532 and / or 533) of the basket (53). For example, the second wire (532) can be inserted into the first groove (164a) of the first support rib (160a). For example, the third wire (533) can be inserted into the second groove (164b) of the second support rib (160b). Consequently, by moving the first duct (100) in the second direction (D2) with respect to the basket (53), the first duct (100) and the basket (53) can be easily coupled.
