次に、第４図及び第５図を参照しつつ、上記戸
車５を引戸１５に取付けた場合の動作状態につい
て説明する。 Next, the operating state when the door roller 5 is attached to the sliding door 15 will be described with reference to FIGS. 4 and 5.

図において引戸１５の上下部前後位置には位置
をずらして２つの戸車５が設けられており、これ
ら各戸車５が建屋開口部の上下走行部１６に配し
た各２本のレール１７ａ，１７ｂに各々別々に係
合して走行し得るようになつている。 In the figure, two door rollers 5 are provided at the front and back positions of the upper and lower parts of the sliding door 15 at different positions, and each of these door rollers 5 is connected to two rails 17a and 17b arranged on the upper and lower running parts 16 of the building opening. They are designed so that they can be engaged and run separately.

まず、引戸１５を全閉にした状態から開放状態
にするには、収納部１８側より順次引戸１５を収
納部１８内へ移動させる。 First, in order to change the sliding door 15 from a fully closed state to an open state, the sliding door 15 is sequentially moved into the storage section 18 from the storage section 18 side.

この場合、第４図に示すように、引戸１５はレ

１７ａ，１７ｂの軌道に追従することとなる。 In this case, as shown in FIG. 4, the sliding door 15 moves linearly along the building at a portion corresponding to the opening of the building by the rails 17a, 17b. In addition, the rails 17a and 17b are bent in the forward direction within the storage section 18, and the two rails 17a and 17b guide the front and rear of the sliding door 15 separately, and the door roller 5
Since the sliding door 15 can be rotated horizontally, the sliding door 15 is sequentially moved in the direction of view while remaining parallel to the building and is retracted, and is completely retracted as shown in FIG. In this case, since the door roller body 3 is biased by the spring 14, it follows the trajectory of the rails 17a, 17b with a slight deviation in the bending start state.

次に、この第５図の状態から引戸１５を引出す
場合には、第５図のように建屋より引戸１５より
順次引き出していけば良い。 Next, when pulling out the sliding door 15 from the state shown in FIG. 5, it is sufficient to sequentially pull out the sliding door 15 from the building as shown in FIG.

に追従することができるという効果がある。[Effects of the invention] As explained above, the door roller of the invention includes a mounting board, a movable member that is movable in the front and back directions with respect to the mounting board, and a movable member that is horizontally rotatable with respect to the movable member. Since the door roller body is provided with an attached door roller body, there is an effect that it can easily follow a traveling part such as a bent rail.

対処することができるという効果がある。 In addition, since the movable member is urged by a spring to the center position of the mounting board in the front-rear direction and is mounted so that it can move in the front-rear direction against the spring, when the running part such as the rail starts to bend, it is horizontal. It is possible to facilitate rotation and reliably follow the traveling part, and as a result, it is possible to reliably deal with deviations from the normal movement of the fittings.
