The hook member 2 can be forcibly moved in the pulling direction by the linear member 3333.

  Further, in the elastic tensioning tool 3, Sa is defined as an interval between the 13 pivotally connected portions of the sliding member 1 and the separation point Q between the drum portion 31 and the linear member 33 when the hook member 2 is temporarily stopped. [Refer to FIG. 4 (A)], 13 points of the pivotal connection portion of the sliding member 1 in the state where the hook member 2 has reached the movement end position (refer to FIG. 4 (B)), the drum portion 31 and the line Assuming that the distance from the separation point Q to the shaped member 33 is Sb, the moving distance of the sliding member 1 is (Sa−Sb), and this moving distance is Sc (see FIG. 4B).

  From the above, the elastic energy of the mainspring 32 may be set such that the drum portion 31 can obtain an amount of rotation corresponding to at least the distance Sc. The movement distance Sc is short, and the diameter of the drum section 31 and the elastic force of the spring 32 are sufficient so that the rotation of the drum section 31 corresponding to the movement distance Sc is sufficient in approximately half rotation. It is preferably set.

  Next, the resistance means 4 serves to reduce the speed in the door closing direction of the sliding member 1 due to the elastic force F of the spring 32 of the elastic tensioner 3. There are various types of resistance means 4. In the first embodiment, as shown in FIGS. 1, 4 and 5B, a pressing portion 41 is mounted. The pressing portion 41 reduces the moving speed of the sliding member 1 in the door closing direction by pressing from a direction substantially orthogonal to the longitudinal direction of the sliding member 1.

The pressing portion 41 includes a pressing plate 411 and a spring mounting portion 412. The pressing plate 411 has a plate shape, and the spring mounting portion 412 is a portion that plays a role of mounting the pressing spring 42 in a stable state on the pressing portion 41.

A pressing portion guide portion 43 is formed on the casing 5 side, and the pressing portion 41 and the pressing spring 42 are mounted in the pressing portion guide portion 43. Specifically, as shown in FIGS. 1B and 1C, the pressing portion guide portion 43 is formed on the second casing portion 52 side, or the second casing portion 52. And the first casing part 51 Each side is divided and formed. One side in the longitudinal direction of the pressing spring 42 may be fixed to the pressing portion guide portion 43.

The portion of the pressing plate 411 that contacts the sliding member 1 is the pressing surface 411a. Called. The pressing surface 411a is formed in a flat shape, and the pressing surface 411a However, the elastic force of the pressing spring 42 can contact the sliding member 1 with an appropriate pressing force. The contact state between the pressing surface 411a and the sliding member 1 generates a resistance force T with respect to the elastic tensioning device 3 by generating appropriate friction, and is caused by the elastic tensioning device 3 of the sliding member 1. The moving speed in the door closing direction can be reduced.

The pressing surface 411a The moving speed in the door closing direction of the sliding member 1 changes appropriately depending on the friction coefficient and the elastic force of the pressing spring 42. The pressed surface 12 of the sliding member 1 and the pressing surface 411 a of the pressing portion 41. Grease may be applied to the part where the contact is made. That is, the pressing surface 411a When the friction between the sliding member 1 and the sliding member 1 is too large, the presence of grease on both contact surfaces reduces the friction coefficient and adjusts the moving speed of the sliding member 1 in the door closing direction. Is.

Furthermore, as a modified example of the resistance means 4 of the first embodiment, a pressing surface 411a serving as a pressing tip of the pressing portion 41. As shown in FIGS. 22A and 22B, the friction material 44 may be attached. The friction material 44 has a sheet shape and is fixed to the pressing surface 411a via an adhesive or the like. There are various types of the friction material 44, and those having a rough surface shape having a large friction coefficient and those having a smooth surface in which a surface having a very small friction coefficient is extremely smooth exist. Then, when adjusting the elastic force F of the spring 32 of the elastic tensioner 3 and the moving speed of the sliding member 1 in the door closing direction by the spring 32 to a desired speed, the friction material 44 having these various friction coefficients. From the above, it is used so as to generate an appropriate resistance T by selecting an appropriate friction coefficient.

Next, as another modification of the resistance means 4 of the first embodiment, as shown in FIG. 21, an adjustment portion 45 that can finely adjust the dimension in the longitudinal direction of the pressing spring 42 may be provided. . The adjusting portion 45 is attached to the pressing portion guide portion 43 of the casing 5. The adjustment portion 45 includes an adjustment end portion 451 and an external screw portion 452 as shown in FIGS. The adjustment end 451 is formed with a protrusion 451a for fixing the pressing spring 42, and the protrusion 451a. A pressing spring 42 is connected to the.

  An inner screw portion 453 is formed in the pressing portion guide portion 43 of the casing 5, and the outer screw portion 452 and the inner screw portion 453 are screwed together (see FIG. 21 (B)). A driver groove 454 is formed in the outer screw portion 452, and the length of the pressing spring 42 in the longitudinal direction is finely adjusted from the outside of the casing 5 to the groove 454 with a tool such as a screwdriver to adjust its elastic force. (See FIG. 21C).

Further, the pressed surface 12 which is a contact surface with the pressing portion 41 of the sliding member 1. As shown in FIG. 21 (A), it may be an inclined surface having an inclination angle θ so as to gradually lower in the door closing direction. By using the pressed surface 12 as an inclined surface, when the sliding member 1 moves in the door closing direction, the pressing portion 41 moves relatively upward relative to the inclined surface. . And the resistance force T with respect to the movement of the sliding member 1 by the press part 41 can be made still larger. This is employed particularly when the elastic force F of the elastic tensioner 3 is too large.

  Next, as the resistance means 4 of the second embodiment, a roller member 46 is used. The roller member 46 is in a stopped state in the door closing direction of the sliding member 1 and is configured to be rotatable in the door opening direction. Yes (see FIGS. 23A and 23B). Specifically, as shown in FIGS. 23B and 23C, the roller member 46 is provided with a pawl mechanism portion 47. The roller member 46 is a roller 461 supported by a holder 462. The holder 462 is attached to the pressing portion guide portion 43 of the casing 5. The pawl wheel mechanism 47 includes a pawl wheel 471 and a pawl 472, and the pawl wheel 471 is fixed to the roller 461.

  When the sliding member 1 moves in the door closing direction, the roller 461 does not rotate but generates friction with the pressed surface 12 of the sliding main body 11 to move the sliding main body 11. The resistance force T with respect to the direction is generated, and the speed of the sliding door 9 can be appropriately reduced (see FIG. 23D). Further, the roller 461 can rotate with respect to the pressed surface 12 of the sliding member 1 when the sliding member 1 moves in the door opening direction. Can be moved with a relatively small force (see FIG. 23E).

Next, as shown in FIG. 24 (A), the resistance means 4 of the third embodiment is a substantially wheel-shaped rolling member 48, and the rolling member 48 has a center of rotation that is centered. . As the material of the rolling member 48, a rubber material is suitable. The sliding member 1 moves from the door opening side toward the door closing side and the rolling member 48 that is in contact with the pressed surface 12 is gradually lowered downward. A distance d between the diameter center p _{0 of the} rolling member 48 and the rotation center p ₁ is set.

  The amount of this distance d may be small. Further, the half circumference of the rolling member 48 and the moving distance of the sliding member 1 are made to substantially coincide. Then, when the sliding member 1 is in an initial state (a state where the sliding member 1 is located on the door open side as shown in FIG. 24A), the sliding member 1 and the rolling member 48 are in contact with each other. The contact position is set at the door closing side end of the sliding member 1. As a result, the sliding member 1 moves in the door closing direction, the rolling member 48 rotates, and the rolling member 48 gradually increases the pressing force against the sliding member 1, and finally the distance d The rolling member 48 presses the pressed surface 12 of the sliding member 1 by the amount of.

  Furthermore, as shown in FIGS. 25 (A) and 25 (B), there is a resistance means 4 of the fourth embodiment that presses both side surfaces in the width direction of the sliding member 1. This is to generate a resistance force T against the movement of the sliding member 1 by the elastic tensioner 3 by sandwiching and pressing both sides in the width direction of the sliding body 11 of the sliding member 1. Furthermore, the resistance means 4 of 5th Embodiment is mounted | worn with the sliding member 1 side (refer FIG. 26). The resistance means 4 includes a spherical body 491, a pressing spring 42, and a housing portion 492. The housing portion 492 is attached to the sliding member 1, and the pressing spring 42 and the spherical body 491 are housed in the housing portion 492. The spherical body 491 is pressed against the upper surface of the casing 5 by the pressing spring 42.

  In the resistance means 4, the sliding member 1 is generated by the door closing force P obtained by subtracting the resistance force T from the elastic force F by generating a resistance force T against the elastic force F that moves the sliding member 1 to the door closing side. And the hook member 2 is moved to the door closing side. That is, the guide traveling body B that supports the sliding door 9 is moved by the force of FT = P, and the initial speed Vn of the sliding door 9 is locked to the guide traveling body B as shown in FIG. The low speed Vm by the door closing force P from the state in which the portion 15b is engaged with the hook member 2 until the door closing is completed can be achieved.

  As shown in FIG. 1, the resistance means 4 generates a resistance force T against the elastic force F that moves the sliding member 1 to the door closing side, and a door closing force P obtained by subtracting the resistance force T from the elastic force F. Thus, the sliding member 1 and the hook member 2 are moved to the door closing side (see FIG. 1B). That is, the guide traveling body 8 that supports the sliding door 9 is moved by the force of FT = P, and the initial speed Vn of the sliding door 9 is locked to the guide traveling body 8 as shown in FIG. The low speed Vm by the door closing force P until the door closing is completed after the part 62 is engaged with the hook member 2 can be achieved.

Next, the locking tool 6 is a guide traveling body 8. 12 (B) and 12 (C), an arm-shaped portion 61 extending along the moving direction and a locking portion 62 formed at the tip of the arm-shaped portion 61 are configured. The locking portion 62 is formed so as to protrude in the horizontal direction with respect to the longitudinal direction of the arm-like portion 61. In the door closing operation, the engaged surface portion 531 contacts the contact piece 22b of the hook member 2 that is temporarily stopped, and the hook member 2 is moved from the engaged surface portion 531 to the main guide portion 53. At the same time, the locking portion 62 is accommodated between the locked piece 22a and the contacted piece 22b and is engaged with the hook member 2 (see FIGS. 13 and 14).

  The locking member 6 is a connecting portion provided on each of the upper guide traveling body 8 and the lower guide traveling body 8, specifically, a traveling portion that is a main portion of the upper and lower guide traveling bodies 8. 81. The upper and lower guide traveling bodies 8 serve to move the sliding door 9 along the upper and lower guide rails 7. The guide rail 7 is formed with one or a plurality of rail portions 71, 71. Each of the rail portions 71 and 71 has a guide opening 72 formed on the lower side (see FIG. 12A).

First, the guide traveling body 8 As shown in FIGS. 1 and 12, the hang roller type corresponds to the guide rail 7, and the traveling unit 81 includes a traveling main body unit 811 and roller units 812 and 812. The traveling main body 811 is provided with a support shaft 82 that serves to adjust the vertical position of the sliding door 9, and a connecting tool 83 for connecting to the sliding door 9 is provided below the support shaft 82. It is installed. The guide traveling body 8 and the sliding door 9 are connected via the connection tool 83.

Further, on the lower side of the sliding door 9, a guide traveling body 8 is provided. Is installed. The lower guide traveling body 8 is substantially the same as the upper guide traveling body 8, but the connecting member 83 is formed in a screw shaft shape or the like and is attached to the lower surface side of the sliding door 9. The guide traveling body 8 is attached to the lower guide rail 7 and slides in the guide rail 7. Similarly to the upper guide rail 7, the door closing tool A may be mounted on the door closing side end of the lower guide rail 7.

  Next, the specific example of the structure which assembles the sliding door 9 and the door closing tool A as the partition between the upper and lower guide rails 7 or a cabinet is shown. First, in the case of a cabinet, as shown in FIGS. 11 and 12, the cabinet is composed of an upper portion 100, both side portions 200, and a bottom portion 300, and its front surface is an opening 400 for installing the sliding door 9. . Therefore, as an example of the first type of assembly, the upper guide rail 7 is mounted on the upper portion 300 of the cabinet C so as to correspond to the upper and lower end portions of the sliding door 9. A lower guide rail 7 is attached to the bottom 300 of the cabinet C.

  As the upper and lower guide rails 7, those having two rail portions 71 and 71 are used so as to have two lanes, respectively (see FIG. 12A). The two sliding doors 9 and 9 can be mounted at 400 openings of the cabinet C. A guide traveling body 8 is mounted on the two rail portions 71 and 71 of the upper guide rail 7. Similarly, a lower guide traveling body 8 is disposed on the two rail portions 71, 71 of the lower guide rail 7, and the connection tool 83 is configured such that the upper and lower guide traveling bodies 8 support the upper and lower ends of the sliding door 9. It connects to the sliding door 9 via connection apparatuses, such as.

  In this way, the sliding doors 9 are arranged on the two lanes (rail portions 71, 71), respectively, and the two sliding doors 9, 9 open and close, respectively. 2 and 3, the sliding door 9 positioned in front of the opening 400 moves to the left end to form a closed state, and the sliding door 9 positioned on the back side (back side) of the sliding door 9 is on the right side. It moves to the end and constitutes a closed state.

  As shown in FIGS. 1, 13 to 15, the casing 5 of the door closing tool A is substantially straight at the door closing side end in the longitudinal direction of the rail portions 71, 71 of the guide rail 7. And connected. That is, it is a structure in which the upper and lower guide rails 7 are continuously connected to the rail portions 71 and 71 in the same line. This is because space saving can be realized by attaching the door closing tool A, and the engaging operation between the upper and lower guide traveling bodies 8 and the door closing tool A can be smoothed.

  Next, as an assembly example of the second type, as shown in FIGS. 16 and 18, the casing 5 of the door closing tool A is arranged in parallel with the upper and lower guide rails 7. Specifically, the casing 5 of the door closing device component (door closing tool) is disposed adjacent to the longitudinal direction of the upper and lower guide rails 7. That is, it is installed so as to be at a right angle to the mounting state of the casing 5 in the case of the first type assembly example described above.

  Further, a spacer 500 for height adjustment is provided between the casing 5 and the upper portion 100 of the cabinet C, and the insertion port of the locking tool 6 in the casing 5 and the locking tool of the guide traveling body 8 are provided. 6 is set to coincide with the position 6 (see FIG. 16). The lower guide rail 7 has a rail portion 71 composed of one lane, and the guide traveling bodies 8 of the two sliding doors 9 and 9 share the rail portion 71 composed of the one lane. .

Furthermore, the lower guide traveling body 8 attached to the two sliding doors 9, 9. In order to prevent the two sliding doors 9 and 9 from interfering with each other, the lower guide traveling body 8 is attached to each of the two sliding doors 9 and 9 only at the door closing side end portion. Also in the lower guide rail 7, the casing 5 of the door closing device constituent part (door closing tool) is mounted on the bottom via a spacer 500. In this way, the locking tool 6 of the lower guide traveling body 8 and the position of the entrance / exit of the casing 5 are matched. Each lower guide traveling body 8 is mounted near a lower end of the sliding door 9 via a bracket.

  The bracket is formed by bending a band plate material into a substantially “L” shape (see FIG. 17). Then, one end of the bracket is in contact with the back side of the sliding door 9 and is fixed by a fixing tool such as a screw. Further, the other end side of the bracket is bolted and connected by a screw shaft-like connection tool 83 provided in the lower guide traveling body 8.

18 shows a door closing device component (door closing tool) in the door closing state at the right end of the cabinet C and the lower guide traveling body 8. The state is shown. As shown in FIGS. 17 (A) and 17 (B), the locking member 6 attached to the upper guide traveling body 8 and the lower guide traveling body 8 in the second type assembly example has an arm-shaped portion 61 as shown in FIGS. Main arm piece 61a The main arm piece 61a and the protruding piece 61b are substantially L-shaped.

The main arm piece 61a The protruding direction is determined by the closing direction of the two sliding doors 9. The main arm piece 61a indicated by the solid line is used for the right closing sliding door 9, and the main arm piece 61a indicated by the imaginary line is used. Is used for the sliding door 9 closed on the left side. The locking tool 6 and the traveling main body 811 may be integrally formed or may be formed as separate members. Since it is set as such a structure, as shown in FIG. 18, the locking tool 6 protrudes in the direction orthogonal to the longitudinal direction of a rail from the upper and lower guide rails 7. As shown in FIG.

  Next, each operation | movement of the door closing of the sliding door 9 and the door opening by the door closing apparatus in 1st type is demonstrated based on FIG. 13 thru | or FIG. FIGS. 13 to 15 show the respective operations of closing and opening the sliding door 9 by the door closing tool A such as the casing 5 attached to the upper guide rail 7 and the upper guide traveling body 8. is there. The upper guide rail 7, the upper guide traveling body 8, and the door closing operation are respectively performed for the lower guide rail 7, the lower guide traveling body 8, and the door closing and opening operation of the sliding door 9 by the door closing tool A. The operation is equivalent to the operation of closing and opening the sliding door 9 by the tool A.

  First, the door closing operation of the sliding door 9 will be described with reference to FIGS. As shown in FIG. 13A, the sliding member 1 and the hook member 2 are pivotally connected, and in the initial state, the engaging portion 23 of the hook member 2 is covered by the casing 5 (first casing portion 51). It is in a temporarily stopped state in a state of being engaged with the engaging surface portion 531. Then, when the sliding door 9 in the open state moves in the door closing direction (from the left side to the right side in FIG. 13A), the sliding door 9 gradually approaches the hook member 2, and as shown in FIG. The distal end of the locking portion 62 comes into contact with the contact piece 22b of the hook member 2.

Further, when the guide traveling body 8 moves in the door closing direction, the locking portion 62 acts so as to press the contact piece 22b, and the rotation base portion 21 of the hook member 2 rotates with respect to the sliding member 1. However, the engaging portion 23 is detached from the engaged surface portion 531 of the casing 5, and the temporarily stopped state of the hook member 2 is released. Specifically, the engaging portion 23 is disengaged from the engaged surface portion 531 while the rotation base portion 21 rotates in the clockwise direction. At this time, the engaging portion 62 of the guide traveling body 8 is engaged with the contact piece 22b of the hook member 2 through the process shown in FIGS. 13C and 14A. 22a and contact piece 22b It fits in the recessed part 22c of the substantially U shape between.

  Then, together with the locking operation of the locking portion 62 and the hook member 2, the temporarily stopped state of the hook member 2 is released, and the sliding surface portion 27 formed in the flat shape of the hook member 2 is substantially the same as the main guide portion. The sliding surface portion 27 of the hook member 2 moves in the door closing direction by the elastic force F of the elastic tensioner 3 together with the guided projection piece 14 of the sliding member 1. When the sliding member 1 and the hook member 2 are moved in the door closing direction by the elastic tensioner 3, the pressed surface 12 formed on the sliding member 1 is resistant by the pressing portion of the pressing portion 41 of the resistance means 4. T operates with respect to the elastic biasing direction by the elastic force F of the elastic tensioner 3.

  As a result, a force obtained by subtracting the resistance force T of the resistance means 4 from the elastic force F of the elastic tensioner 3, that is, a force FT becomes a substantial door closing force P. The sliding door 9 is decelerated from the initial door closing speed Vn by the person's door closing operation by the door closing force P, and becomes a gentle speed Vm by the door closing force P, and the door closing operation is performed. It is forcibly moved to the door closing side, reaches the door closing direction end, and completes the door closing operation (see FIGS. 14B and 19).

This series of door closing operations is performed by the upper and lower guide traveling bodies 8 by the door closing tool A mounted on the upper and lower guide rails 7 respectively. At the same time, the sliding door 9 is moved in a decelerating direction in the door closing direction via the locking tool 6. As a result, when the sliding door 9 is forcibly moved to the door closing side by the door closing tool A, the sliding door 9 is decelerated in a well-balanced manner in the vertical direction and can move stably in the door closing direction without play.

  Next, the door opening operation | movement of the sliding door 9 is demonstrated based on FIG. First, as shown in FIG. 15 (A), the hook member 2 is positioned near the door closing side (right side in FIG. 15 (A)) in the initial state, and the hook member 2 is attached to the guide traveling body 8. The stopper 6 is in a locked state with the locked piece 22 a of the hook member 2. And as shown in FIG.15 (B), the locking tool 6 with which the guide traveling body 8 was mounted | worn by moving the said sliding door 9 in a door opening direction [from FIG. 15 (B) to the left side from the right side]. The hook member 2 and the sliding member 1 are forcibly moved to the door opening side along the main guide portion 53 so as to pull the locked piece 22a of the hook member 2 in the locked state.

  When the sliding door 9 is further moved in the door opening direction and the hook member 2 reaches the engaged surface portion 531, the sliding restriction projection 17 comes into contact with the door opening side end of the sliding restriction portion, and the sliding member 1. This serves as a stopper in the sliding operation, and the sliding of the sliding member 1 is stopped. At this time, the engaging portion 23 of the hook member 2 has reached the engaged surface portion 531 location. Further, by continuing the door opening operation of the sliding door 9, the hook member 2 moves the rotation base 21 so that the locked piece 22 a of the hook member 2 is pulled out by the locking portion 62 of the guide traveling body 8. Rotate through.

  Specifically, the hook member 2 rotates counterclockwise around the rotation base 21, and the engaging portion 23 moves to the engaged surface portion 531 and is engaged. The hook member 2 is engaged with the engaging portion 23 and the engaged surface portion 531 by an appropriate pressure by the elastic force F of the sliding member 1 and the elastic tensioner 3 connected to the sliding member 1. The contact state is maintained, whereby the hook member 2 is temporarily stopped at the engaged surface portion 531.

Since the hook member 2 is inclined at the door opening side, the locked piece 22a. As a result, the locking portion 62 of the guide traveling body 8 is detached from the locked piece 22a, the locked state between the locking portion 62 and the hook member 2 is released, and the sliding door 9 further Move to the opening side and complete the opening operation. Since the main guide portion 53 and the engaged surface portion 531 are formed on the first casing portion 51 side, the main guide portion 53 and the engaged surface portion 531 are described with imaginary lines. .

The series of door opening operations is performed by the upper and lower guide traveling bodies 8 by the door closing tool A mounted on the upper and lower guide rails 7 respectively. However, the sliding door 9 can be moved against the elastic force F of the elastic tensioning tool 3 in the door closing tool A through the respective locking tools 6. This makes it possible to perform a forcible movement in a stable door opening direction with good balance and no play in the upper and lower portions of the sliding door 9.

  Next, the door closing and opening operations of the two sliding doors 9 in the second type are also substantially the same as those in the first type described above, and the upper and lower guide rails 7 are rail sections 71 and 71 of two lanes. Yes, except that the guide rail 7 is composed of a rail portion 71 having only one lane, the door 9 is closed by the guide rail 7, the guide traveling body 8, and the door closing tool A attached to the guide rail 7. The door closing operation and the door opening operation of the sliding door 9 by the door closing device components (door closing tool) such as the guide rail 7, the guide traveling body 8, and the casing 5 are substantially the same. FIG. 20 is a perspective view of an embodiment in which the sliding door 9 is a room partition. When the sliding door 9 is used as a partition, the guide rail 7 may be only the upper part.

  According to the present invention, a gentle door closing operation of the sliding door 9 can be obtained, and the initial operations of the door closing and the door opening can be made stable without play. That is, the sliding member 1 and the hook member 2 are pivotally connected so that the hook member 2 can swing freely. Further, the force that the sliding member 1 moves in the casing 5 in the door closing direction depends on the elastic force F of the elastic tensioning tool 3, but the resistance means 4 that reduces this elastic force F is provided. The traveling body 8 can be moved in the door closing direction by a force obtained by subtracting the resistance force T of the resistance means 4 from the elastic force F of the elastic tensioner 3 and performs a very good and stable door closing operation. Can do. Both the upper and lower guide rails 7 are fitted with a door closing tool A, and the upper and lower guide traveling bodies 8 can perform stable door closing and opening operations without play by the respective locking tools 6. It is.

  Further, the hook member 2 is configured such that the sliding member 1 swings only at the position of the door opening side end portion, and the engaging portion 23 is freely engageable with the engaged surface portion 531, thereby By bringing the sliding door 9 in the vicinity of the door closing side end, the sliding door 9 is forcibly drawn to the door closing side end, and the speed of the sliding door 9 is moderately reduced immediately before the door closing end to obtain a good door closing operation. be able to. Further, the entire door closing device can be made compact, and the space for incorporating the sliding door device directly into the guide rail 7 of the sliding door 9 into the sliding door device can be reduced. In addition, the sliding door 9 can be made stable and free of backlash without tilting the sliding door 9 in the initial operation of closing and opening the door.

That is, the locked piece 22a And the contacted piece 22b The hook member 2 is formed so as to be swingable with respect to the sliding member 1, and the engaging portion 23 protrudes upward by the turning operation of the turning base portion 21. . In the hook member 2, the sliding member 1 swings only at the position of the door opening side end portion, and the engaging portion 23 is engageable with the engaged surface portion 531. Therefore, in the case of the door closing operation, the hook member 2 can be temporarily stopped in a state where the hook member 2 is stable on the door opening side in the initial state. In other words, the hook member 2 is less likely to swing in the left-right direction when performing a swinging motion, and therefore can be extremely troublesome.

  Further, when the locking portion 62 of the locking tool 6 mounted on the guide traveling body 8 tries to lock the hook member 2, the locking member 62 is smoothly locked and the sliding member 1 and the hook member are locked by the elastic tensioning tool 3. 2 is moved in the door closing direction. At this time, the resistance force T of the resistance means 4 acts on the elastic tensioner 3 so as to reduce the elastic force F, and the sliding member 1 and the hook for moving the guide traveling body 8 are moved. The member 2 can be moved within the casing 5 at an appropriately moderate speed. The sliding member 1 and the hook member 2 move along the longitudinal direction in the casing 5, and the moving direction is the same as the moving direction of the guide traveling body 8 in the guide rail 7.

  Therefore, the casing 5 can be mounted on the end portion of the guide traveling body 8 in the longitudinal direction, and therefore is substantially integrated with the guide rail 7 so that the apparatus of the present invention can be easily mounted and the mounting location can be saved. Can be realized. Further, the upper and lower guide rails 7 are each provided with a door closing tool A, so that when the sliding door 9 is closed and opened, the upper and lower guide rails 7 and the door closing tool A and the upper and lower guides respectively attached thereto.
