It can be assembled and the gripping member 50 is permanently fixed in the opening 11d. When the gripping member 50 is attached to the housing 11, the peripheral edge of the opening 11d is sandwiched between each claw portion and the frame portion 52. This prevents the gripping member 50 from coming off from the opening 11d.

When attaching a conventional gripping member by inserting it into the opening 11d from the outside of the housing 11, first insert the claw provided on one side in the vertical direction Z into the opening 11d, and then insert the gripping member in the vertical direction Z. Push all the claws provided on the other side into the opening 11d. At this time, at least one of the inner edge of the opening 11d and all the claws provided on the other side in the vertical direction Z is slightly elastically deformed, and the claw is pushed into the opening 11d. In this case, if the protruding height of the claw that is pushed in through elastic deformation is large, the claw gets caught on the inner edge of the opening 11d and cannot be pushed into the opening 11d. needed to be made smaller. Therefore, when attaching the conventional gripping member by pushing it into the opening 11d from the outside of the housing 11, it was difficult to make the claw portions have a sufficient protruding height, and it was difficult to firmly attach the gripping member to the housing 11.

On the other hand, according to the first embodiment, the gripping member 50 includes the main body 51, the first claw 54 projecting upward from the upper wall 51a, and the claw member 60 fixed to the main body 51. , has. The claw member 60 has a second claw portion 62 that is hooked onto the peripheral edge of the opening 11d from inside the housing 11. The second claw portion 62 is passed through the through hole 56 provided in the lower wall portion 51b from the internal space of the main body portion 51, and protrudes downward from the lower wall portion 51b. Therefore, by inserting and arranging the main body part 51 into the opening 11d before the claw member 60 is fixed, even if the protrusion height of the first claw part 54 is large to some extent, the first claw The main body portion 51 provided with the portion 54 can be easily inserted into the opening portion 11d. Further, the claw members 60 are inserted into the main body 51 after being inserted into the opening 11d from an internal space that opens to the outside, that is, the finger insertion space 53, and the claw members 60 are fixed to the main body 51. I can do it. Therefore, even if the protrusion height of the second claw part 62 is large to some extent, the second claw part 62 can be easily assembled. Thereby, both the protrusion height of the first claw part 54 and the protrusion height of the second claw part 62 can be increased to a certain extent, and the gripping member 50 can be firmly attached to the opening 11d. As described above, according to the first embodiment, it is possible to improve the workability of attaching the gripping member 50 while ensuring the attachment strength of the gripping member 50.

Furthermore, since the gripping member 50 can be attached to the opening 11d from the outside of the casing 11 as described above, as long as the opening 11d is provided in the casing 11, it can be attached to any part of the casing 11. The gripping member 50 can be attached even if it is the case. As a result, the degree of freedom in designing the attachment location of the gripping member 50 in the housing 11 can be improved compared to the case where the gripping member 50 is held between two or more members forming the housing 11. Therefore, the gripping member 50 can be attached to a location of the housing 11 that is easy for the operator to grip. Furthermore, since the attachment of the gripping member 50 is completed by fixing the claw member 60 to the main body 51 from the outside of the casing 11, the gripping member 50 can be correctly attached to the opening 11d from the outside of the casing 11.

Department. Therefore, when fixing the claw member 60 to the main body 51 temporarily fixed to the opening 11d, the second claw The through hole 56 through which the portion 62 passes is easily visible from the outside of the housing 11. This makes it easier to fix the claw member 60 to the main body 51. Therefore, the gripping member 50 can be more easily attached to the opening 11d. Note that this effect is more effectively obtained when the upper part of the finger insertion space 53 is covered by the cover part 52d and the lower surface of the upper wall part 51a is difficult to see from the outside of the housing 11.

Further, according to the first embodiment, the claw member 60 has a base portion 61 to which the second claw portion 62 is connected. The base portion 61 covers the through hole 56 in the internal space of the main body portion 51 . Therefore, the through hole 56 can be closed by the base 61, and foreign matter such as rainwater can be prevented from entering the inside of the casing 11 through the through hole 56. As a result, even if the through hole 56 is provided in the lower wall portion 51b located on the lower side in the vertical direction in order to facilitate attachment of the claw member 60 as described above, foreign matter such as rainwater can escape from the through hole 56. Intrusion into the inside of the casing 11 can be suppressed.

Further, according to the first embodiment, the second claw portion 62 has an engaging portion 62b that is hooked to the peripheral edge of the through hole 56 on the outside of the main body portion 51. A peripheral portion of the through hole 56 is sandwiched between the engaging portion 62b and the base portion 61 in the vertical direction Z. Therefore, the claw member 60 can be prevented from coming off from the through hole 56 in the vertical direction Z. Thereby, the claw member 60 can be firmly fixed to the main body part 51. Further, by pushing the second claw portion 62 into the through hole 56, the claw member 60 can be easily fixed to the main body portion 51. Further, since it is not necessary to separately provide another member to fix the claw member 60 to the main body portion 51, an increase in the number of parts of the outdoor unit 10 can be suppressed.

Further, according to the first embodiment, the recess 55 is provided in the surface of the lower wall portion 51b facing the internal space of the main body portion 51. The base 61 is disposed within the recess 55. Therefore, it is possible to suppress the base portion 61 from being arranged so as to protrude upward from the lower wall portion 51b. Thereby, when the operator inserts his or her fingers into the internal space of the main body portion 51, that is, the finger insertion space 53, it is possible to prevent the base portion 61 from becoming an obstacle.

Further, according to the first embodiment, the gripping member 50 has the frame portion 52 that protrudes at least above and below the main body portion 51 . An upper portion of the peripheral edge of the opening 11d is sandwiched between a portion of the frame portion 52 that protrudes above the main body portion 51 and the first claw portion 54. A lower portion of the peripheral edge of the opening 11 d is sandwiched between a portion of the frame portion 52 that protrudes lower than the main body portion 51 and the second claw portion 62 . Therefore, the gripping member 50 can be more firmly and stably attached to the opening 11d. Further, as shown in FIGS. 7 and 8, when the main body 51 without the claw members 60 is inserted into the opening 11d, the upper part of the peripheral edge of the opening 11d is inserted into the frame 52. It can be sandwiched between the upper part and the first claw part 54, and the lower part of the frame part 52 can be supported by abutting against the lower part of the peripheral edge of the opening 11d. Thereby, even before the claw member 60 is fixed, the main body portion 51 can be attached to the opening 11d with a certain degree of stability. Therefore, before fixing the claw member 60, the main body portion 51 can be suitably temporarily fixed to the opening 11d. Therefore, the work of fixing the claw member 60 to the main body portion 51 can be easily performed.

Further, according to the first embodiment, the heat exchange unit including the gripping member 50 is the outdoor unit 10. The outdoor unit 10 has a larger mass than the indoor unit 20. Therefore, the outdoor unit 10 is more difficult to transport than the indoor unit 20.
