  In the glass door 7, the door main body 28 includes at least a pair of left and right first reinforcing members 32a and 32b arranged in the vertical direction along the left and right side frame portions 42a and 42b, and a lower frame portion 42c. And a third reinforcing member 32c that is disposed in the left-right direction along the left and right ends and is connected to the lower ends of the first reinforcing member 32a and the second reinforcing member 32b. The side edges 40a and 40b are in contact with the first reinforcing member 32a and the second reinforcing member 32b of the door main body 28, and the lower edge 40c is in contact with the third reinforcing member 32c of the door main body 28 and presses against the back surface of the door main body 28. Since it has a structure, even when the window hole 25 of the door main body 28 is made large, the door main body 28 can be reinforced by the glass plate unit 31, and the first to third reinforcing members 3 used for the door main body 28. The strength of the glass door 7 can be easily secured while suppressing waste of A～32c.

  That is, the door main body 28 includes left and right first reinforcing members 32a and second reinforcing members 32b and a third reinforcing member 32c connected to the lower ends of the first and second reinforcing members 32a and 32b. Therefore, it is possible to use a strip-like sheet metal material or the like for the first to third reinforcing members 32a to 32c as compared with a conventional integral structure reinforcing plate or the like, and waste of material can be reduced.

  On the other hand, the side edges 40a and 40b of the glass plate unit 31 are brought into contact with the first reinforcing member 32a and the second reinforcing member 32b of the door main body 28, and the lower edge 40c is brought into contact with the third reinforcing member 32c of the door main body 28, respectively. Since the glass plate unit 31 is configured to press against the back surface of the door main body 28, the door main body 28 can be reinforced by the glass plate unit 31, and the strength of the door main body 28 can be easily secured. Further, since the door main body 28 is reinforced by the glass plate unit 31, it is not necessary to attach a reinforcing plate having an integral structure to the entire back surface of the door main body 28 as in the prior art, and the first to third belt-sheet-like sheet metal materials are not required. Since the door main body 28 may be reinforced by the reinforcing members 32a to 32c, the usage amount of the first to third reinforcing members 32a to 32c can be reduced, and the manufacturing cost can be reduced.

  Between the third reinforcing member 32c and the lower part of the glass plate unit 31, there is an engaging means 29 that the glass plate unit 31 is detachably engaged from above, and the engaging means 29 is provided on the upper side of the door main body 28. Since there is a fastening means 30 for fastening the upper side of the glass plate unit 31 to the door main body 28 side as a fulcrum, the glass plate unit 31 can be easily attached to the door main body 28 and the glass plate unit 31 is attached to the door main body 28. It can be easily fixed to the back surface.

  In addition, when the glass plate unit 31 is fastened by the fastening means 30, the substantially entire periphery of the glass plate unit 31 comes into contact with the back surface of the door main body 28 including the first to third reinforcing members 32a to 32c. The relative movement in the contact surface direction between the door main body 28 and the glass plate unit 31 in the fastened state can be prevented, and the reinforcing effect of the door main body 28 by the glass plate unit 31 can be increased.

  The third reinforcing member 32c has a pair of left and right receiving portions 72c that are bent to the back side and receive the glass plate unit 31 from the lower side in the engaged state of the engaging means 29, and correspond to the receiving portions 72c. Since there are a pair of engaging means 29 on the left and right, distortion in the twisting direction of the glass door 7 can be easily prevented. In particular, since the upper side of the glass plate unit 31 is positioned with respect to the door main body 28 by the positioning means 90, the fastening means 30 is such as to press the upper side of the glass plate unit 31 toward the door main body 28 side. Distortion in the twisting direction between the main body 28 and the glass plate unit 31 can be prevented.

  In addition, each engagement means 29 includes an engagement protrusion 86a that protrudes downward from the glass plate unit 31, and an engagement hole 86b that is formed in the receiving portion 72c and engages with the engagement protrusion 86a. The engaging means 29 can be easily provided between the glass plate unit 31 and 28.

  Of the first reinforcing member 32a and the second reinforcing member 32b that reinforces the door main body 28, the thickness Tb of the second reinforcing member 32b on the locking operation means 12 side is set to the thickness of the first reinforcing member 32a on the glass door hinge 9 side. Since the thickness of the plate 62 is larger than the thickness Ta, and the holder 62 of the glass door locking means 11 is integrally formed on the second reinforcing member 32b by bending, the rigidity of the holder 62 can be sufficiently secured. Compared with the case where 62 is fixed to the second reinforcing member 32b by welding or the like, the manufacturing is easier, and the manufacturing cost of the second reinforcing member 32b can be reduced.

  Further, since the plate thickness Ta of the first reinforcing member 32a is smaller than that of the second reinforcing member 32b, the material is compared with the case where a sheet metal material having the same thickness as the second reinforcing member 32b is used for the first reinforcing member 32a. Can be wasted. That is, the first reinforcing member 32 a side of the door main body 28 is connected to the front frame 3 side via the upper and lower glass door hinges 9. When the glass door 7 is attached to the front frame 3, the front frame 3 It can resist the twisting of the door main body 28. Accordingly, by using a thin sheet metal material for the first reinforcing member 32a, it is possible to easily ensure a predetermined strength while suppressing waste of material. In addition, since the 1st reinforcement member 32a has the bending edge 52a and the fitting edge 53a, the rigidity of 1st reinforcement member 32a itself can be easily ensured by this bending edge 52a and the fitting edge 53a.

  The third reinforcing member 32c has a receiving portion 72c, and the receiving portion 72c receives the load of the glass plate unit 31 from below, but the plate thickness Tc of the third reinforcing member 32c is the plate of the first reinforcing member 32a. Since it is thicker than the thickness Ta, the load of the glass plate unit 31 can be reliably supported. Further, since the length of the receiving portion 72c can be easily secured even if the plate thickness Tc of the third reinforcing member 32c is reduced, the same plate thickness Tb as that of the second reinforcing member 32b in which it is difficult to secure the width of the hanging tool 84. In this respect, it is possible to prevent waste of materials.

  The third reinforcing member 32c is provided with a plurality of mounting portions 74c projecting upward from the receiving portion 72c in the left-right direction, and the glass plate unit 31 is in contact with the back surface of the mounting portion 74c. Compared to the structure in which the glass plate unit 31 is in contact with the back side of the third reinforcing member 32c on the lower side, a receiving portion 72c can be provided longer in the upper portion of the third reinforcing member 32c. The strength of the third reinforcing member 32c can be improved.

  Further, the portion of the first to third reinforcing members 32a to 32c that contacts the glass plate unit 31 is substantially flush with the portion of the door main body 28 that contacts the glass plate units 31 other than the first to third reinforcing members 32a to 32c. The substantially entire circumference of the glass plate unit 31 is in contact with the back surface of the door main body 28 including the first to third reinforcing members 32a to 32c. For this reason, it is not necessary to provide an uneven structure on the holding member 35 or the like on the glass plate unit 31 side, and the structure on the glass plate unit 31 side can be simplified.
