In addition, the deformation of the front panel 11b around the cock mounting shaft 40 could be prevented. Further, since the front panel 11b is supported by a small area like the reinforcing boss 20d, the cooling heat of the cooling water in the cooling water tank 20 can be prevented from being transmitted to the front panel 11b. Was also prevented from occurring.

  Further, in the beverage dispenser 10 of this embodiment, the cylindrical portion 20c that covers the outside of the shaft main body portion 41 inside the flange portion 43 in the radial direction between the front panel 11b of the housing 11 and the front wall 20a of the cooling water tank 20. Are provided, and the reinforcing boss portion 20d is arranged radially outside the flange portion 43 of the cock mounting shaft 40. Thereby, even if the fastening nut 45 is excessively fastened to the screw portion 41d of the shaft main body portion 41, the flange portion 43 is provided on both the inside and outside in the radial direction of the inner cylindrical portion 20c in the radial direction and the outer reinforcing boss portion 20d. The rearward movement was prevented, and the front panel 11b was further prevented from being deformed around the cock mounting shaft 40.

  In addition, in the beverage dispenser 10 of this embodiment, the front panel 11b is deformed around the cock mounting shaft 40 by providing the reinforcing bosses 20d on the left and right sides straddling the cock mounting shaft 40 in the radial direction. Was reliably prevented on both the left and right sides. The reinforcing bosses 20d may be provided on both upper and lower sides of the cock mounting shaft 40 in the radial direction, or the reinforcing bosses 20d may be provided on a circumference concentric with the center axis of the cock mounting shaft 40. A plurality (for example, two or more) may be provided along the direction.

  Further, in the beverage dispenser 10, the reinforcing boss 20d is formed integrally with the front surface of the front wall 20a of the cooling water tank 20. Thereby, it was possible to prevent the front panel 11b from being deformed around the cock mounting shaft 40 without increasing the number of components. The present invention is not limited to the case where the reinforcing boss 20d is integrally formed on the front surface of the front wall 20a of the cooling water tank 20, but the reinforcing boss 20d is formed on the front surface of the front wall 20a of the cooling water tank 20. And the rear surface of the front panel 11b may be provided separately, or the reinforcing boss 20d may be integrally provided on the rear surface of the front panel 11b.

  The housing 11 of this embodiment includes a base body 11a that forms a bottom wall, a front panel 11b, a rear panel 11c, and right and left sides that form front, rear, right, and left side walls above the base body 11a. Although the side panels 11d and 11e and the lid 11f forming the ceiling wall so as to cover the upper surface opening formed by the panels 11b to 11e are provided, the present invention is not limited to this, and the present invention is not limited to this.
