The user moves the cover 453 further downward with respect to the main body portion 452, and arranges the protrusion 45u at the lower end portion of the engaging groove 45i. When the protrusion 45u is arranged at the lower end of the engagement groove 45i, the protrusion 45u is supported by the edge of the engagement groove 45i and the cover 453 is engaged with the main body 452.

図６に示すように、カバー４５３は、本体部４５２に対して係合された状態において、側面部４５ｏの後側の端部が前板４３と当接する。カバー４５３は、上面部４５ｑのビス穴４５ｘに通されたビスＳが本体部４５２の雌ねじ部４５ｖの雌ねじ４５ｗに螺合されることにより、本体部４５２に螺着され装着される。 As shown in FIG. 6, in a state where the cover 453 is engaged with the main body portion 452, the rear end portion of the side surface portion 45o comes into contact with the front plate 43. The cover 453 is screwed and attached to the main body portion 452 by screwing the screw S passed through the screw hole 45x of the upper surface portion 45q into the female screw 45w of the female screw portion 45v of the main body portion 452.

本実施形態の冷蔵庫１によれば、ハンドル４５が冷蔵室扉１１Ａの前板４３の正面Ｆに取り付けられる。そのため、冷蔵庫１は、ハンドル４５が使用者から視認されやすく、設計上の想定通りに使用者にハンドル４５を掴ませて冷蔵室扉１１Ａを開閉させることができる。ハンドル４５は着脱可能なカバー４５３を持つ。そのため、カバー４５３は、外観が変更されること、又は例えば抗菌カバー若しくは小型のコンピュータが内蔵されるカバー等とされて機能を付加若しくは変更されることが可能である。 According to the refrigerator 1 of the present embodiment, the handle 45 is attached to the front surface F of the front plate 43 of the refrigerator compartment door 11A. Therefore, in the refrigerator 1, the handle 45 is easily visible to the user, and the user can grasp the handle 45 and open / close the refrigerating room door 11A as expected in the design. The handle 45 has a removable cover 453. Therefore, the appearance of the cover 453 can be changed, or the function can be added or changed, for example, as an antibacterial cover or a cover in which a small computer is built.

ハンドル４５は、当て板４５１を持つ。そのため、前板４３の剛性が低い場合でも、ハンドル４５の剛性が補強され、使用者の操作感が向上する。 The handle 45 has a backing plate 451. Therefore, even when the rigidity of the front plate 43 is low, the rigidity of the handle 45 is reinforced and the operability of the user is improved.

ハンドル４５には、窪み部４５９が形成される。そのため、ハンドル４５が掴みやすくなり、使用者の操作感が向上する。 A recessed portion 459 is formed in the handle 45. Therefore, the handle 45 can be easily grasped, and the user's operability is improved.

ハンドル４５のカバー４５３は、カバー４５３の内側面に形成される突起部４５ｕと本体部４５２の外側面に形成される溝４５ｇとが係合することにより、本体部４５２に装着される。ハンドル４５は、カバー４５３と本体部４５２とがビス止めされる。そのため、カバー４５３と本体部４５２との相対位置の固定はお互いを係合することによりなされ、カバー４５３と本体部４５２とが少なくとも１箇所でビス止めされてカバー４５３と本体部４５２とが強固に固定される。 The cover 453 of the handle 45 is attached to the main body 452 by engaging the protrusion 45u formed on the inner surface of the cover 453 with the groove 45g formed on the outer surface of the main body 452. The cover 453 and the main body 452 of the handle 45 are screwed together. Therefore, the relative positions of the cover 453 and the main body 452 are fixed by engaging each other, and the cover 453 and the main body 452 are screwed at at least one place to firmly hold the cover 453 and the main body 452.

ハンドル４５は、カバー４５３に形成される突起部４５ｕが、本体部４５２の溝４５ｇに係合され、カバー４５３が本体部４５２に装着される。カバー４５３は、溝４５ｇの導入溝４５ｈに沿って前板４３側に導入され、導入溝４５ｈの後側の端部において突起部４５ｕが係合溝４５ｉに収まる。そのため、カバー４５３は、前板４３に押し付けられた状態で本体部４５２に係合され、カバー４５３と前板４３との間に隙間が生じにくく、カバー４５３が安定して固定される。使用者がカバー４５３を掴んでハンドル４５を引いたときに本体部４５２とカバー４５３とが離れることが抑制される。本体部４５２とカバー４５３とが離れることが抑制されることにより、本体部４５２とカバー４５３とのビス止め箇所に負荷がかかることが抑制される。 In the handle 45, the protrusion 45u formed on the cover 453 is engaged with the groove 45g of the main body 452, and the cover 453 is attached to the main body 452. The cover 453 is introduced to the front plate 43 side along the introduction groove 45h of the groove 45g, and the protrusion 45u fits in the engagement groove 45i at the rear end portion of the introduction groove 45h. Therefore, the cover 453 is engaged with the main body portion 452 in a state of being pressed against the front plate 43, a gap is unlikely to occur between the cover 453 and the front plate 43, and the cover 453 is stably fixed. When the user grabs the cover 453 and pulls the handle 45, the main body 452 and the cover 453 are prevented from being separated from each other. By suppressing the separation of the main body 452 and the cover 453 from each other, it is possible to prevent a load from being applied to the screwed portion between the main body 452 and the cover 453.

ハンドル４５の本体部４５２は、側壁部４５８が第１リブ４５ａで連結されて形成される。そのため、本体部４５２は、体積及び重量が抑えらているが、十分な強度を持つ。 The main body portion 452 of the handle 45 is formed by connecting the side wall portions 458 with the first rib 45a. Therefore, although the volume and weight of the main body portion 452 are suppressed, the main body portion 452 has sufficient strength.

本体部４５２は、側壁部４５８に、使用者が冷蔵室扉１１Ａを開閉するときに使用者が指をかける窪み部４５９が形成される。本体部４５２は、窪み部４５９の前側で第１リブ４５ａ同士を連結する第２リブ４５ｂを持つ。そのため、使用者が冷蔵室扉１１Ａを開閉しやすい。使用者が冷蔵室扉１１Ａを開閉するときに窪み部４５９に作用する前後方向の力に対して、第２リブ４５ｂが窪み部４５９を補強する。そのため、本体部４５２が破損しにくい。 The main body portion 452 is formed with a recessed portion 459 on the side wall portion 458 on which the user puts his / her finger when opening / closing the refrigerator compartment door 11A. The main body portion 452 has a second rib 45b that connects the first ribs 45a to each other on the front side of the recessed portion 459. Therefore, it is easy for the user to open and close the refrigerator compartment door 11A. The second rib 45b reinforces the recessed portion 459 against the force in the front-rear direction acting on the recessed portion 459 when the user opens and closes the refrigerator compartment door 11A. Therefore, the main body 452 is not easily damaged.

カバー４５３は、上面部４５ｑが本体部４５２にビス止めされる、そのため、カバー４５３は、本体部４５２に強固に固定される。ビス止め箇所は、ハンドル４５の上部に形成されるため、目立たない。 The upper surface portion 45q of the cover 453 is screwed to the main body portion 452, so that the cover 453 is firmly fixed to the main body portion 452. Since the screwing portion is formed on the upper part of the handle 45, it is inconspicuous.
