A distribution box panel unit (10) comprises: a front panel (110) which is formed by a square-shaped panel, and includes a vent hole (112) including a semicircle cap heading to a front side, and a discharge hole (114) which is arranged in a row of a lower unit; a first connection unit (120) which is formed by the square-shaped panel, and includes a vent hole (122) including the semicircle cap heading to the front side and a first connection hole (124) formed in an edge part; and a second connection unit (130) which includes a box shape with one side which is opened, and includes a vent hole (132) including the semicircle cap heading to the front side and a spacer (134) formed in the edge part. The vent hole (122) of the first connection unit (120) is dislocated with vent holes (112,132) of the front panel (110) and the second connection unit (130). The vent hole (122) includes the spacer (134) at an inner edge of the second connection unit (130), and is connected to the first connection hole (124) of the first connection unit (120) by using a bolt (126). The second connection unit (130) is formed as the distribution box panel unit (10) by welding the front panel (110). |
