In addition, when the windshield 6 is retrofitted at the site where the showcase is installed at the request of the user, there is a problem that it takes time to store and dispose of the long cover piece 9 removed from the front cap 7.

  The present invention has been made in view of the above points, and as an accessory part of the front cap as in the conventional structure, a cover piece for fitting in the concave groove portion of the cap and closing the opening surface of the groove is separately prepared. Without opening the windshield, the opening surface of the groove of the front cap is naturally blocked, and when the windshield is attached, the windshield has been improved so that it can be stably held in the insertion position without rattling. It aims at providing the structure of a front cap.

In order to achieve the above object, according to the present invention, a showcase having a configuration in which a front cap made of a resin is attached to an upper end portion of a front wall of an open front body case serving as a heat insulating housing. , A concave groove for inserting and supporting the windshield in an upright position at the top of the cap along the longitudinal direction of the front cap is formed, and projects from the upper edge of the groove along the longitudinal direction of the concave groove. A fin-shaped cover member having bendability and rubber elasticity is provided so as to cover the opening end surface , and the cover member is folded into the groove of the groove portion when the windshield is inserted, and the wall surface of the groove portion and the windshield plate It is configured so as to cover the opening end surface of the groove portion when the windshield is removed and the windshield is removed.

  With the configuration of the present invention described above, in the state where the windshield is removed, a fin-like cover member (soft elastomer material) integrally formed on the upper edge of the groove portion of the front cap covers the opening end surface of the groove, and foreign matter falls. Prevent dust from entering and accumulating.

  On the other hand, when the base of the windshield is pushed into the concave groove of the front cap from above, the cover member is folded into the groove of the concave groove together with the windshield, and between the wall surface of the concave groove and the plate surface of the windshield. It is sandwiched in a compressed state. As a result, the windshield is firmly held without backlash due to the compression elasticity of the cover member. Further, when the windshield is pulled out from this state, the cover member itself returns to its original position due to rubber elasticity and closes the opening surface of the groove portion.

  Therefore, there is no need for a cover part (cover piece 9 in FIG. 5) to be used by fitting into the concave groove as an accessory part of the front cap as in the conventional structure, and in addition to the effect of reducing the part cost, It is possible to carry out the retrofitting work of the windshield, which is carried out at the installation site, without generating waste parts.
