- the roller supported by the upper end surface is configured to drop into the recess in order to move the door body, and since the roller suddenly enters the recess, the reaction force acting in the direction of suppressing the swing is constantly received. It cannot be said that the state of support of the roller by the rail is always good. Therefore, there is room for improvement in suppressing the swinging of the door body more effectively by further stabilizing the support state.
- the present invention has been made in view of the above circumstances, and an object thereof is to provide a sliding door device that can effectively suppress the swing of the door body.
- the present invention has a concavely formed inner surface, a rail on which a first support surface and a second support surface that are not parallel to each other are formed, and a first traveling body that is in rolling contact with the first support surface. And a hanger having a second traveling body that is in rolling contact with the second support surface, and a door body that is moved in the longitudinal direction of the rail via the hanger, and viewed along the longitudinal direction of the rail.
- the sliding door device is formed such that the first support surface and the second support surface are closer to each other as they extend toward the bottom of the inner surface.

Is stable. Therefore, the door main body moves smoothly, the swinging of the door main body can be effectively suppressed, and the first and second traveling bodies can be separately rolled on the corresponding support surfaces. Uneven wear of the second traveling body can be prevented.
- the rail is disposed so as to extend along an outer peripheral edge of an opening that is opened and closed by the door body, and the first support surface is the second support when viewed along the longitudinal direction of the rail.
- the first support surface may include a flat part and an inclined part that inclines from the flat part toward the opening part.
- the door body can be moved in the longitudinal direction of the rail and moved to the opening side, and a door structure in which the door body approaches the opening side can be configured.
- the sliding door device according to the present invention is effective in swinging the door body by stabilizing the support state of the first traveling body and the second traveling body by the rail by the concave inner surface of the rail. Can be suppressed.
- the first and second traveling bodies can be separately rolled on the corresponding support surfaces, so that the first and first 2 Uneven wear of the traveling body can be effectively prevented.

- the operation feeling of a door main body can be changed suitably.
- the rail includes a closed rail portion disposed on the outer peripheral edge side of the opening, and an open rail portion disposed at a position farther from the outer peripheral edge of the opening than the closed rail portion.
- the flat portion and the inclined portion are formed on the first support surface of the closed rail portion and the first support surface of the open rail portion, respectively, and the hanger is closed.
- a first hanger and a second hanger arranged side by side from the side rail portion side toward the open rail portion side, wherein the first hanger includes the two first traveling bodies and the two first hangers.
- One second traveling body disposed between one traveling body, and the second hanger is disposed between the two second traveling bodies and the two second traveling bodies.
- the first traveling body, and an inclination of the inclined portion of the open-side rail portion The distance between the starting point and the end portion of the closed rail portion adjacent to the open rail portion is equal to or less than the distance between the two first traveling bodies in the first hanger. Also good.
- the first traveling body of the first hanger is moved to the opening portion side by the inclined portion of the open rail portion. Without passing through the inclined portion of the open side rail portion, it is possible to transfer to the open side rail portion. As a result, the door body can be separated from the opening as much as possible without causing any hindrance to movement, so that the door body can be prevented from being left behind.
- the first traveling body and the second traveling body are arranged so as to be shifted in the longitudinal direction of the rail.
- the first traveling body and the second traveling body when viewed along the longitudinal direction of the rail, in other words, the first traveling body and the second traveling body partially overlap each other on the projection surface projected in the longitudinal direction of the rail.
- the first traveling body and the second traveling body can be arranged. Thereby, the occupation area of a 1st traveling body and a 2nd traveling body can be suppressed.
- the first traveling body and the second traveling body are arranged so as to partially overlap on the projection surface projected in the longitudinal direction of the rail, the first traveling body and the second traveling body
- the occupied area that is, the size of the first traveling body and the second traveling body in the prospective direction and the direction of finding can be suppressed as compared with the case where the first traveling body and the second traveling body are arranged without overlapping.
- the entire door device can be reduced in size.
- the expected directions of the first traveling body and the second traveling body since the size in the direction of finding can be suppressed, the case that accommodates the first traveling body, the second traveling body, and the driving device on the outer peripheral edge side of the opening that is opened and closed by the door body has design and dimensional restrictions. Even if it is a case, possibility that the 1st traveling body and the 2nd traveling body which were enlarged in the said case can be accommodated increases. Therefore, it is possible to avoid a situation in which it is difficult to install the door device due to an increase in the size of the traveling body.
- the first traveling body and the second traveling body are rollers, and when viewed along the longitudinal direction of the rail, the rotation axis of the first traveling body is Orthogonal to the normal line of the first support surface, the rotation axis of the second travel body is orthogonal to the normal line of the second support surface, and the first travel body and the second travel body are
- the projection plane may be arranged so as to be shifted in the longitudinal direction and partially overlap on the projection plane projected in the longitudinal direction of the rail.
- the hanger has two first traveling bodies and one second traveling body, and the second traveling body is disposed between the two first traveling bodies.
- two first traveling bodies and one first traveling body may be provided, and the first traveling body may be disposed between the two second traveling bodies.
- the door is centered on an axis that is orthogonal to the longitudinal direction of the rail and passes between the first support surface and the second support surface when viewed along the longitudinal direction of the rail.
- the traveling body located on the end side of the hanger prevents rotation.
- the amount of compression of the coil spring used in the door device of JP2537064Z increases as the door body approaches the closed state, and the elastic force of the coil spring is maximized when the door body is in the closed state.
- the maximum elastic force accumulated in the coil spring assists the movement of the door body.
- the elastic force of the coil spring decreases as the door body is moved in the opening direction.
- the inclined portion of the recess where the roller rolls for separation from the recess is formed at a constant angle. Therefore, in a state where the roller is located in the recess, the resistance received from the door body increases as the opening operation proceeds. Therefore, there is room for improvement in enabling the door body to be opened smoothly.
- the sliding door device includes a fixing member fixed to the door main body, a rod main body held by the fixing member and movable in a direction parallel to the longitudinal direction of the rail, and the fixing member.
- An operation auxiliary rod having an elastic member provided between the rod main body and an axial extension line of a tip portion of the rod main body, and the operation auxiliary rod of the operation auxiliary rod accompanying the movement of the door main body to the closed state side. It may further comprise a receiving member that abuts against the tip of the rod body during the movement, elastically deforms the elastic member, and pushes the rod body toward the fixed member.
- the member means that the first traveling body of the hanger reaches the end of the flat portion of the first support surface on the inclined portion side, or reaches the inclined portion of the first support surface.
- the inclined portion may have a plurality of inclined regions having different inclination angles.
- the resistance received from the door body in each of the plurality of inclined regions can be adjusted while utilizing the elastic force of the elastic member when opening the closed door body.
- the closed door body can be lifted and opened smoothly with a small force, or the packing (the outer peripheral edge of the opening) and the door body are in close contact with each other with a small force Can be released quickly. Therefore, the door main body moved to the opening side when moving to the closed state side can be opened smoothly.
- the inclination angle is set to be larger in the inclined region where the elastic force of the elastic member takes a larger value when the first traveling body arrives.
- the inclination angle is set to be relatively large, so that the door body faces the open state side in the inclined area.
- the resistance received from the door body when moving is increased, the movement of the door body is assisted by a large elastic force.
- the inclination angle is set relatively small, so that the elastic force is reduced, but the door body is directed toward the open state side. The resistance received from the door body when moving in the inclined region is reduced. Therefore, it is possible to suppress unevenness in resistance generated in the door body. Thereby, the door main body of the state moved to the opening part side at the time of the movement to the closed state side can be opened smoothly.
- the elastic member has an elastic force proportional to the amount of elastic deformation, and in the plurality of inclined regions, the inclination angle of the inclined region located on the closed state side of the door body is larger than that of the inclined region. You may be larger than the inclination-angle of the inclination area
