It is possible to prevent the occurrence of high friction due to. That is, as shown in FIG. 1B, even when the lower end surface of the sliding door 10 is lowered due to the construction error of the upper rail 7, the processing error of the sliding door 10, the swing or vibration when the sliding door 10 is opened and closed, The guide body 21 is lowered so as to be pushed into the accommodating portion 26a. Thereby, it can suppress that the guide body 21 pushes up the groove bottom 13a of the guide groove 13 of the sliding door 10 excessively.

Moreover, since the guide body 21 is raised / lowered with respect to the casing 26 embedded in the floor 2, the lower end of the sliding door 10 is compared with the case where the casing 26 is installed on the floor 2, for example. The gap with the floor 2 can be effectively reduced.
In addition, a protruding curved surface portion (rolling member) 25 that is in contact with the groove bottom 13 a of the guide groove 13 is provided at the leading end portion of the guide body 21 in the protruding direction. Therefore, for example, the frictional resistance against the groove bottom 13a of the guide body 21 urged by the urging member 28 can be reduced as compared with the case where the front end surface of the guide body 21 has an upward flat surface shape. 10 can be smoothly guided at the lower end side. Thereby, for example, even when an automatic closing mechanism for assisting the sliding door 10 in the sliding direction is provided, the sliding door 10 is prevented from stopping halfway due to the frictional resistance of the guide body 21. can do.

In the present embodiment, the projecting curved surface portion 25 is spherical. Accordingly, the projecting curved surface portion 25 is brought into contact with the groove bottom 13a of the guide groove 13 in a point contact manner. Thereby, for example, compared with the case where the projecting curved surface portion 25 has a cylindrical surface shape in line contact with the groove bottom 13 a of the guide groove 13, the distal end portion of the guide body 21 with respect to the groove bottom 13 a of the guide groove 13. The frictional resistance can be effectively reduced.
Further, in the present embodiment, the rolling element 25 that constitutes the projecting curved surface portion that rolls in contact with the groove bottom 13a of the guide groove 13 is provided at the tip of the guide body 21 so as to be rotatable. Therefore, the frictional resistance of the front end portion of the guide body 21 with respect to the groove bottom 13a of the guide groove 13 can be made extremely small, and the lower end portion side of the sliding door 10 can be guided more smoothly.

In addition, in this embodiment, although the example which made the rolling element 25 the spherical shape which comprises a spherical surface is shown, it can be rotated to the surroundings of the axis in alignment with a door thickness direction instead of such an aspect, It is good also as what was made into the roller shape made into the salient curved surface shape seeing the outer peripheral surface in the circumferential direction. Or it is good also as what was made into the shape of the cylindrical roller which comprises the cylindrical surface as a projecting curved surface part. That is, the projecting curved surface portion 25 may be configured to abut on the groove bottom 13a of the guide groove 13 in line contact.
Further, instead of the embodiment in which the projecting curved surface portion is the rolling element 25, the guide body 21 may be fixedly (integrally) provided at the distal end portion of the guide body 21. For example, a projecting curved surface portion having a spherical shape (semispherical shape) or a cylindrical surface shape (semi-cylindrical surface shape) may be fixedly provided at the distal end portion of the guide body 21. Further, when a projecting curved surface portion having a cylindrical surface shape (semi-cylindrical surface shape) is provided at the distal end portion of the guide body 21, the portion that is in line contact with the groove bottom 13 a is the door thickness direction or the door width. It may be provided so as to extend in the direction. Moreover, it is good also as a structure which provided multiple such various curved surface parts 25 in the front-end | tip part of the guide body 21. FIG.
