If the refrigerant leaks into the atmosphere, there is a risk of some impact on global warming. Furthermore, if the refrigerant is flammable or slightly flammable, if there is a combustible material at the destination of the leaked refrigerant, the refrigerant may promote combustion and cause a fire to become larger, so sufficient measures are required to prevent the leakage of the refrigerant.

  • the worker can insert the first pipe 18a through the second opening 32k and hold the first pipe 18a in the second holding portion 32a.
  • the first opening 31k and the second opening 32k open in different directions, it is difficult for the first pipe 18a to pass through both the first opening 31k and the second opening 32k at the same time, and it is possible to prevent the mounting member 30 from coming off the first pipe 18a.
  • the second opening 32k opens in a direction perpendicular to the extension direction of the rotation axis J.
  • the opening direction of the second opening 32k can be made to coincide with the rotation direction of the second part 32 around the rotation axis J. This allows the first pipe 18a to pass smoothly through the second opening 32k during the process of transitioning from the preliminary state shown in FIG. 4 to the attached state shown in FIG. 5.
  • the assembly process of the mounting member 30 to the first pipe 18a can be simplified.
  • the first opening 31k opens in the same direction as the extension direction of the rotation axis J.
  • the opening widths of both the first opening 31k and the second opening 32k are smaller than the pipe diameter of the first pipe 18a.
  • the first pipe 18a is less likely to come off the first holding portion 31a and the second holding portion 32a. This effect can be obtained at least for the holding portion when the opening width of at least one of the first opening 31k and the second opening 32k is smaller than the pipe diameter of the first pipe 18a.
  • the opening direction of the second opening 32k coincides with the rotation axis J.
  • the opening width of the second opening 32k smaller to make it difficult for the second holding portion 32a to come off the first pipe 18a, it is possible to suppress the second part 32 from rotating in the reverse direction around the hinge portion 39. Therefore, according to this embodiment, the reliability of the holding of the first pipe 18a and the second pipe 18b by the mount member 30 can be improved.
  • the second wall portion 32b is provided with a groove portion 32g that accommodates the second pipe 18b.
  • the groove portion 32g may be provided in the first wall portion 31c, or the first wall portion 31c and the second wall portion 32b may have overlapping groove portions. In other words, the groove portion 32g may be provided in either one or both of the first wall portion 31c and the second wall portion 32b.
  • the mounting member 30 of this embodiment is made of a rubber material. With this configuration, even if the outdoor unit 10 is subjected to an impact or vibration, the elasticity of the rubber material can suppress the load applied to the first pipe 18a and the second pipe 18b. In addition, the tension of the rubber material can stably hold the first pipe 18a and the second pipe 18b on the mounting member 30.
  • the outdoor unit 10 of this embodiment is an outdoor unit 10 of a refrigeration cycle device 100 equipped with the above-mentioned mount member 30, and has a first pipe 18a through which the refrigerant 19 flows, a second pipe 18b branching off from the first pipe 18a, and a cap member 18e that closes the opening of the second pipe 18b.
  • the first pipe 18a through which the refrigerant 19 flows and the second pipe 18b as a charge plug for filling the first pipe 18a with the refrigerant 19 can be held by the mount member 30.
  • the mounting member is described as holding the refrigerant circulating pipe (first pipe) and the refrigerant charging pipe (second pipe) of the outdoor unit, but the use of the mounting member is not limited to this embodiment.
  • the first holding portion and the second holding portion hold the refrigerant circulating pipe, and the first wall portion and the second wall portion sandwich the refrigerant charging pipe.
  • a configuration in which the first holding portion and the second holding portion hold the refrigerant charging pipe, and the first wall portion and the second wall portion sandwich the refrigerant circulating pipe may also be adopted.
  • the refrigeration cycle device provided with the mounting member is an air conditioner.
  • the refrigeration cycle device provided with the above-mentioned mounting member 30 is not limited to the above-mentioned configuration, and may be, for example, a heat pump water heater.
