There is. At this time, the edge of the regulation arm portion 63C extends along the vertical direction and faces forward in the front-rear direction DX. The release operation member 65 is urged from the front side to the rear side in the front-rear direction DX. Therefore, the connecting member 62 is urged in the clockwise direction in FIG. 11 not only by the urging force from the connecting member urging member 64 but also by the pressing force from the release operation member 65 and is stable at the open position. Be maintained.

When the shaft-shaped anchor A is inserted into the notch 61a from the rear, the anchor A contacts the operation arm portion 63B and pushes the operation arm portion 63B forward in the front-rear direction DX, whereby the connecting member 62 is shown in FIG. Rotate counterclockwise. As the connecting member 62 rotates in the counterclockwise direction, the release operating member 65 is once pushed toward the front side in the front-rear direction DX by the end edge of the regulation arm portion 63C. Then, as shown in FIG. 13, the connecting member 62 rotates to a position where the regulating arm portion 63C does not restrict the movement of the releasing operation member 65 to the rear side in the front-rear direction DX. At this time, the release operation member 65 moves to the rear side in the front-rear direction DX due to the urging force from the release operation member urging member (not shown). As a result, as shown in FIG. 12, the release operation member 65 enters below the regulation arm portion 63C. Then, the release operation member 65 is maintained at the connected position by the urging force from the release operation member urging member (not shown).

As shown in FIG. 12, when the release operation member 65 enters below the regulation arm portion 63C, the release operation member 65 comes into contact with the regulation arm portion 63C, so that the release operation member 65 rotates in the clockwise direction. Be regulated. As a result, even if the pushing force of the anchor A into the notch 61a is released, the connecting member 62 is maintained at the holding position shown in FIG.

The connecting arm portion 63A of the connecting member 62 at the open position shown in FIG. 12 extends in the vertical direction DZ across the notch 61a in a side view. Therefore, the anchor A is restricted from coming out of the groove 62a by the connecting arm portion 63A. The shaft-shaped anchor A is stably held in the notch 61a by holding the release operation member 65 at the connecting position shown in FIG. 12 and holding the connecting member 62 at the holding position shown in FIG. .. In this way, the connector 60 holds the anchor A and connects it to the anchor A. On the other hand, as shown in FIG. 13, by pulling the release operation member 65 forward along the front-rear direction DX to the position of FIG. 13 which does not restrict the rotation of the regulation arm portion 63C toward the open position, the connector 60 The connection to anchor A can be released.

Next, the intermediate frame member 80 and the intermediate transmission member 85 will be described. As shown in FIGS. 8 and 9, the intermediate frame member 80 is connected to the connector frame 61 of the connector 60 at the rear end. The intermediate frame member 80 and the connector frame 61 are fixed to each other. The intermediate frame member 80 is composed of, for example, a metal tubular member. As described above, a large number of positioning holes 81 are provided on the upper surface of the intermediate frame member 80 at equal intervals along the front-rear direction DX.

As shown in FIGS. 10 to 13, the intermediate transmission member 85 is connected to the release operation member 65 of the connector 60 at the rear end. The intermediate transmission member 85 is fixed to the release operation member 65 via a fixing tool such as a screw. The intermediate transmission member 85 is operably supported by the intermediate frame member 80.

The intermediate transmission member 85 is movable relative to the intermediate frame member 80 in the front-rear direction DX. For example, one of the intermediate frame member 80 and the intermediate transmission member 85 is provided with an induction slot extending along the front-rear direction DX, and the other of the intermediate frame member 80 and the intermediate transmission member 85 is inserted into the induction slot and is inserted into the induction slot. A guide introduction portion that can move in the guide hole along the longitudinal direction of the head is provided. According to such a configuration, the relative movement of the intermediate frame member 80 and the intermediate transmission member 85 in the front-rear direction DX can be stably guided. In the illustrated fixed unit 50, as shown in FIG. 10, a first induction slot 86 extending along the front-rear direction DX is provided in the intermediate transmission member 85. Then, as shown in FIGS. 8 and 9, a pin-shaped first lead insertion portion 82 to be inserted into the first guide slot 86 is provided in the intermediate frame member 80. The intermediate transmission member 85 can be manufactured, for example, as a resin molded portion.

Next, the connection release member 70 will be described. The disconnection member 70 extends from the intermediate frame member 80 to the front side in the front-rear direction DX. The disengagement member 70 is operably supported by the intermediate frame member 80. In the illustrated example, the disconnection member 70 is movable relative to the intermediate frame member 80 in the front-rear direction DX. As described above, the intermediate frame member 80 is fixed to the child seat body 11 via the position adjusting mechanism 45. Therefore, the disconnection member 70 can operate with respect to the child seat main body 11.

As shown in FIGS. 6 and 7, the illustrated disconnection member 70 extends forward from the holding hole 27 of the child seat body 11 in the front-rear direction DX. As shown in FIGS. 7 and 8, the disconnection member 70 extends along the front-rear direction DX and is inserted into the holding hole 27 of the child seat body 11 in the rear, and the disconnection main body 71 and the disconnection main body 71. It has a connection release operation unit 72, which is located in front of the vehicle and bulges outward in the width direction. The connection release operation unit 72 includes an operation surface 72a that extends in the width direction DY and faces rearward in the front-rear direction DX. The width of the width direction DY of the connection release operation unit 72 increases from the front side to the rear side along the front-rear direction DX.

In the illustrated fixed unit 50, as shown in FIG. 9, the rear portion of the disconnection main body 71 has a cylindrical shape with a quadrangular cross section. More specifically, the disconnection main body portion 71 includes a main wall portion 71a facing outward in the width direction DY, an opposing wall portion 71b facing the main wall portion 71a and the width direction DY, and the main wall portion 71a and the facing wall. It includes a pair of side wall portions 71c that connect the portions 71b. The pair of side wall portions 71c are arranged so as to face the vertical DZ. The facing wall portion 71b is provided only in the rear portion in the front-rear direction DX. The front end portion of the intermediate frame member 80 is inserted into the cylindrical portion of the disconnection member 70. According to such a configuration, the relative movement of the intermediate frame member 80 and the disconnection member 70 in the front-rear direction DX can be stably guided. The disconnection member 70 can be manufactured, for example, as a resin molded portion.

Further, one of the intermediate frame member 80 and the disconnection member 70 is provided with an induction slot extending along the front-rear direction DX, and the other of the intermediate frame member 80 and the disconnection release member 70 is inserted into the induction slot and the induction slot. A guide introduction portion that can move in the guide hole along the longitudinal direction of the head is provided. According to such a configuration, the relative movement of the intermediate frame member 80 and the disconnection member 70 in the front-rear direction DX can be stably guided. In the illustrated fixed unit 50, as shown in FIG. 14, a second induction slot 83 extending along the front-rear direction DX is provided in the intermediate frame member 80. Then, as shown in FIGS. 8, 9 and 14, a pin-shaped second lead insertion portion 73 to be inserted into the second guide slot 83 is provided in the disconnection member 70.

By the way, the intermediate transmission member 85 transmits the operation of the connection release member 70 to the connector 60. As a result, by operating the connection release member 70, the release operation member 65 of the connector 60 operates via the intermediate transmission member 85, and the connection of the connector 60 to the anchor A is released. As described above, by moving the release operation member 65 of the connector 60 and the intermediate transmission member 85 fixed to the release operation member 65 to the front side along the front-rear direction DX, the connector 60 can be connected to the anchor A. It can be released. Then, in the illustrated example, by operating the connection release member 70 so as to move forward along the front-rear direction DX, the release operation member 65 moves forward along the width direction DY via the intermediate transmission member 85. It moves, which allows the connector 60 to be disconnected from the anchor A.

Therefore, the disconnection member 70 that can move relative to the intermediate frame member 80 is connected to the intermediate transmission member 85. However, in the illustrated example, the disconnection member 70 and the intermediate transmission member 85 are connected to each other so as to be relatively movable by a certain length along the movement direction when the disconnection member 70 is operated. In the illustrated example, the disconnection member 70 and the intermediate transmission member 85 are connected to each other so as to be relatively movable along the front-rear direction DX by a certain length.

As a configuration that allows the disconnection member 70 and the intermediate transmission member 85 to move relative to each other along the front-rear direction DX, one of the connection release member 70 and the intermediate transmission member 85 is provided with an elongated hole extending along the front-rear direction DX and is connected. An insertion portion movably inserted into the elongated hole may be provided on the other side of the release member 70 and the intermediate transmission member 85. In the illustrated fixing unit 50, as shown in FIGS. 10 and 14, the intermediate transmission member 85 is provided with a third guide slot 87 into which the second guide insertion portion 73 provided in the disconnection member 70 is inserted. Has been done. The second lead insertion portion 73 can move in the third lead slot 87 along the front-rear direction DX, which is the longitudinal direction of the third lead slot 87.

As described above, the intermediate transmission member 85 transmits the operation of the disconnection member 70 to the connector 60. Therefore, the length of the disengagement member 70 and the intermediate transmission member 85 that can be moved relative to each other along the front-rear direction DX is within a certain range, and in particular, the length of the disengagement member 70 and the intermediate frame member 80 relative to each other along the front-rear direction DX. It is less than the movable length. As a result, when the disconnection member 70 is relatively moved in the front-rear direction DX with respect to the intermediate frame member 80, the intermediate transmission member 85 is moved along the front-rear direction DX by a length less than the movement length of the connection release member 70. Can be moved. In the illustrated example, the second lead insertion portion 73 of the disconnection member 70 is inserted into the first guide insertion portion 82 of the intermediate frame member 80 and the three guide slot 87 of the intermediate transmission member 85. The length of the third guide slot 87 provided in the intermediate transmission member 85 along the front-rear direction DX is larger than the length of the first guide insertion portion 82 provided in the intermediate frame member 80 along the front-rear direction DX. Is also getting shorter. Therefore, the connection release member 70 initially moves relative to both the intermediate frame member 80 and the intermediate transmission member 85 in the front-rear direction DX, and then, in synchronization with the intermediate transmission member 85, moves in the front-rear direction with respect to the intermediate frame member 80. It becomes possible to move relative to DX.

Further, in the illustrated example, the connection release member 70 is urged in the direction opposite to the direction of movement when the connection release member 70 is operated. Therefore, it is possible to effectively prevent the disconnection member 70, which can move relative to the intermediate transmission member 85 by a certain length, from rattling with respect to the intermediate transmission member 85. As a specific configuration, as shown in FIG. 10, a first urging member 51 is provided between the disconnection member 70 and the intermediate transmission member 85. The first urging member 51 is made of an elastic material such as a tension spring or an elastic structure. The first urging member 51 is connected to the first urging member support portion 74A of the disconnection member 70 and the tip end portion of the intermediate transmission member 85. Therefore, the disconnection member 70 is urged to the rear side in the front-rear direction DX by the first urging member 51. According to such a first urging member 51, when the connection release member 70 is pulled forward in the front-rear direction DX, the connection release member 70 first refers to both the intermediate frame member 80 and the intermediate transmission member 85. It moves relative to the front side in the front-rear direction, and then moves relative to the front side in the front-rear direction with respect to the intermediate frame member 80 in synchronization with the intermediate transmission member 85.

Next, the regulation release member 75 and the operation regulation member 79 will be described. As described above, the motion restricting member 79 is a member that regulates the motion of the disconnection member 70. On the other hand, when the regulation release member 75 is operated, it acts on the operation restriction member 79 to release the restriction on the operation of the connection release member 70.

In particular, the motion restricting member 79 regulates the relative motion of the disconnection member 70 with respect to the intermediate frame member 80. As a specific configuration, a regulation slot 56 is provided on one of the disconnection member 70 and the intermediate frame member 80 so that the other of the disconnection member 70 and the intermediate frame member 80 can move in the regulation slot 56. The operation restricting member 79 may be supported. In this example, the regulation slot 56 extends along a direction orthogonal to the first slot 56a extending along the moving direction of the disconnecting member 70 during operation and the moving direction of the disconnecting member 70 during operation. It has a second elongated hole portion 56b. The first elongated hole portion 56a and the second elongated hole portion 56b are connected to each other. Further, the motion restricting member 79 is supported by one of the decoupling member 70 and the intermediate frame member 80 so as to be movable along a direction orthogonal to the moving direction of the decoupling member 70 during operation, and can be moved to the regulated elongated hole 56. It is inserted in. In this example, the regulation release member 75 may be operated to move the operation restriction member 79 along a direction orthogonal to the movement direction of the connection release member 70 at the time of operation.

In the illustrated fixing unit 50, as shown in FIGS. 8 to 10, a regulation slot 56 is provided in the disconnection member 70. The regulation slot 56 is provided at a position facing the main wall portion 71a and the facing wall portion 71b of the disconnection main body portion 71 in the width direction DY, respectively. The first elongated hole portion 56a of the regulated elongated hole 56 extends along the front-rear direction DX. The second elongated hole portion 56b of the regulated elongated hole 56 extends along the vertical DZ. The front end portion of the first elongated hole portion 56a in the front-rear direction DX and the upper end portion of the second elongated hole portion 56b in the vertical direction DZ are connected to each other.

The operation restricting member 79 is configured as a pin-shaped member extending in the width direction. The motion restricting member 79 is supported by the intermediate frame member 80 so as to be movable in the vertical direction. Support elongated holes 84 are formed in each of the pair of wall portions facing the width direction DY of the intermediate frame member 80 (see FIG. 14). The support elongated hole 84 extends in the vertical direction, and the motion restricting member 79 can move in the support elongated hole 84 in the vertical direction. The movement restricting member 79 passes through the restricting elongated hole 56 of the disconnection member 70 as well as the supporting elongated hole 84 of the intermediate frame member 80. The second elongated hole portion 56b and the supporting elongated hole 84 of the regulated elongated hole 56 extend within the same height range in the vertical direction DZ. Further, the first elongated hole portion 56a of the regulated elongated hole 56 is located at the same height as the upper end portion of the supporting elongated hole 84. By locating the operation restricting member 79 at the upper end of the support elongated hole 84, the motion restricting member 79 can move in the first elongated hole portion 56a of the regulated elongated hole 56. That is, by moving the operation restricting member 79 to the upper end portion of the support elongated hole 84, the connection release member 70 can be made relatively movable in the front-rear direction DX with respect to the intermediate frame member 80.

The regulation release member 75 acts on the operation regulation member 79 by operating. The illustrated regulation release member 75 moves the operation regulation member 79 located in the second slot 56b to the first slot 56a by being operated. As a specific configuration, as shown in FIG. 14, the regulation release member 75 is formed with a drive slot 78 through which the operation regulation member 79 has passed. The drive slot 78 includes a first hole 78a and a third hole 78c extending along the front-rear direction DX, which is a moving direction when the disconnection member 70 is operated, and a first hole 78a and a second hole 78b. It includes a second hole 78b that connects to each other. The second hole portion 78b is inclined with respect to the front-rear direction DX. The first hole portion 78a and the second hole portion 78b are located at different heights in the vertical direction DZ. The first hole 78a is located at the same height as the lower end of the regulated elongated hole 56, and the third hole 78c is located at the same height as the upper end of the regulated elongated hole 56. In the illustrated example, the first hole 78a is located on the rear side in the front-rear direction DX, and the third hole portion 78c is located on the front side in the front-rear direction DX. The second hole portion 78b is located between the first hole portion 78a and the third hole portion 78c in the front-rear direction DX. In such an example, by moving the regulation release member 75 to the rear side along the front-rear direction DX, the movement regulation member 79 is moved upward to the front-rear direction DX of the connection release member 70 with respect to the intermediate frame member 80. Can be allowed to move relative to each other.

That is, in the illustrated example, the movement direction of the connection release member 70 during the operation of the connection release member 70 for releasing the connection of the connector 60 to the anchor A releases the restriction on the operation of the connection release member 70. It is parallel to the moving direction of the deregulating member 75 during the operation of the deregulating member 75, and is along the front-rear direction DX. Therefore, the operability when operating both the connection release member 70 and the regulation release member 75 is excellent. Further, the movement of the connection release member 70 during the operation of the connection release member 70 for releasing the connection of the connector 60 to the anchor A is the movement of the restriction release member 75 for releasing the restriction on the operation of the connection release member 70. The direction is opposite to the movement of the regulation release member 75 during operation. Therefore, it is possible to effectively prevent the connector 60 from being unintentionally disconnected from the anchor A due to an erroneous operation.

Further, in the illustrated example, the moving direction of the connection release member 70 during the operation of the connection release member 70 for releasing the connection of the connector 60 to the anchor A is from the connection position of FIG. 12 to the release position of FIG. It is parallel to the moving direction of the release operation member 65 up to, and is along the front-rear direction. Further, the movement of the disconnection release member 70 and the movement of the release operation member 65 at this time are in the same direction. According to this example, it is possible to effectively suppress the increase in size of the fixed unit 50.

In the illustrated fixing unit 50, as shown in FIGS. 9 and 10, the deregulation member 75 is operably supported by the decoupling member 70. The deregulation member 75 extends elongated along the front-rear direction DX. The deregulation member 75 passes through a cylindrical portion located on the rear side of the decoupling member 70 in the front-rear direction DX. Further, as shown in FIGS. 6 to 9, the front end portion of the regulation release member 75 in the front-rear direction DX is exposed from the connection release member 70. An opening 70a is formed at the front end portion of the disconnection member 70 in the front-rear direction DX. The front-rear direction DX of the deregulation member 75 has a deregulation operation portion 76 exposed from the opening 70a as a front end portion thereof. The deregulation operation portion 76 of the deregulation member 75 exposed through the opening 70a of the decoupling member 70 can be pushed to the rear side in the front-rear direction DX.

As shown in FIGS. 9 and 10, the regulation release member 75 is provided with an opening 75a. The disengagement member 70 has a second urging member support portion 74B protruding in the width direction DY at a position inside the opening 75a. A second urging member 52 is provided in the opening 75a. The second urging member 52 is made of an elastic material such as a compression spring or an elastic structure. The second urging member 52 is located between the second urging member support portion 74B of the disconnection member 70 and the regulation release member 75. The second urging member 52 urges the deregulation member 75 on the front side in the front-rear direction with respect to the decoupling member 70.

Next, the operation of the fixing unit 50 when the connecting tool 60 is released from the anchor A of the vehicle will be described.

First, in a state where the connector 60 is connected to the anchor A, as shown in FIG. 12, the release operation member 65 of the connector 60 and the intermediate transmission member 85 fixed to the release operation member 65 are in the front-rear direction DX. It is located on the rear side. Then, as shown in FIG. 13, by moving the release operation member 65 to the front side in the front-rear direction DX, the connection to the anchor A by the connector 60 can be released. The movement of the release operation member 65 to the front side is realized by operating the connection release member 70.

However, as described above, the second urging member 52 urges the deregulation member 75 to the front side in the front-rear direction DX with respect to the decoupling member 70. Since the deregulation member 75 is located on the front side in the rearward DX with respect to the decoupling member 70, as shown in FIG. 14A, the drive slot 78 of the deregulation member 75 has its first hole 78a. In, it overlaps with the support elongated hole 84 of the intermediate frame member 80 in the width direction DY. That is, the motion restricting member 79 supported in the support elongated hole 84 is located at the lower end portion of the support elongated hole 84 that intersects with the first hole portion 78a. At this time, the operation restricting member 79 passes through the restricting elongated hole 56 of the disconnection member 70 at the lower end portion of the second elongated hole portion 56b. Therefore, in the state of FIG. 14A, when the motion restricting member 79 comes into contact with the wall portion that partitions the second elongated hole portion 56b, the connection release member 70 moves relative to the intermediate frame member 80 in the front-rear direction DX. Is formed.

Therefore, by operating the regulation release member 75 before operating the connection release member 70, the operation restriction of the operation of the connection release member 70 by the operation restriction member 79 is released. Specifically, the regulation release member 75 is pushed to the rear side in the front-rear direction DX with respect to the connection release member 70. As shown in FIG. 14B, the operation restricting member 79 that has passed through the regulation elongated hole 56 of the decoupling member 70 and the support elongated hole 84 of the intermediate frame member 80 is placed in the drive elongated hole 78 of the deregulating member 75. It moves from the 1st hole 78a to the 3rd hole 78c via the 2nd hole 78b. That is, the operation restricting member 79 is guided by the drive elongated hole 78 and moves upward in the first elongated hole portion 56a and the supporting elongated hole 84 of the regulated elongated hole 56 in the vertical direction DZ. As shown in FIG. 14B, the motion restricting member 79 reaches the second elongated hole portion 56b from the first elongated hole portion 56a of the regulated elongated hole 56. As shown in FIG. 14B, the motion restricting member 79 finally reaches the front end of the drive slot 78.

As described above, the disconnection member 70 and the intermediate transmission member 85 are connected so as to be relatively movable in the front-rear direction DX. However, the disconnection member 70 is maintained at a position close to the intermediate transmission member 85 by the first urging member 51. That is, when the deregulation member 75 is pushed to the rear side, the decoupling member 70 is also pushed to the rear side via the deregulation member 75, but the decoupling member 70 is already reared by the first urging member 51. It is in a state of being moved to the side. Therefore, the regulation release member 75 can be stably operated while the connection release member 70 is stopped.

Next, while the deregulation member 75 is pushed rearward with respect to the decoupling member 70, that is, while maintaining the relative positions of the decoupling member 70 and the deregulation member 75, the deregulation member 75 is connected together with the deregulation member 75. The release member 70 is moved to the front side in the front-rear direction DX. As a result, the connection release member 70 moves relative to the intermediate frame member 80 toward the front side in the front-rear direction DX. With this relative movement, the movement restricting member 79 supported by the supporting elongated hole 84 of the intermediate frame member 80 is inside the first elongated hole portion 56a extending in the front-rear direction DX of the regulated elongated holes 56 of the disconnection member 70. To move.

The connection release member 70 is connected to the intermediate transmission member 85 via the second lead insertion portion 73 inserted into the third guide slot 87 of the intermediate transmission member 85. When the disengagement member 70 moves forward by a certain length with respect to the intermediate transmission member 85, in other words, when the second lead insertion portion 73 moves within the third guide slot 87 by a movable length, FIG. As shown in C), the second lead insertion portion 73 comes into contact with the wall portion that partitions the third guide slot 87.

The second lead insertion portion 73 of the disconnection member 70 also passes through the second guide slot 83 of the intermediate frame member 80. The length of the second lead slot 83 of the intermediate frame member 80 along the front-rear direction DX is longer than the length of the third guide slot 87 of the intermediate transmission member 85 along the front-rear direction DX. Therefore, in the state of FIG. 14C, the second lead insertion portion 73 of the disconnection member 70 is not in contact with the wall portion that partitions the second guide slot 83. Therefore, the connection release member 70 can move further to the front side in the front-rear direction DX with respect to the intermediate frame member 80 in which the second guide slot 83 is formed.

By the way, the seat S of the vehicle on which the child seat 10 is placed has raised portions SA on both sides of the seat surface. By supporting the buttocks of the passenger seated in the seat S from both sides, the raised portion SA can impart stability in the width direction DY of the passenger and improve the riding comfort. On the other hand, as shown in FIG. 6, the raised portion SA covers the lower portion of the pedestal 20 from the side.

In the conventional child seat, the operation switch for operating the connector has a housing fixed to the child seat body and a disconnection member operably supported by the housing. Then, the portion exposed from the housing of the disconnection member was operated with a finger. However, in the conventional child seat, there is a problem that it is very difficult to operate because the disconnection member is only slightly exposed from the housing because it is covered with the raised portion SA.

In this regard, in the illustrated child seat 10, the disconnection member 70 extends forward from the child seat body 11 at a position in front of the connector 60. Therefore, the child seat body 11 can function as a housing for the disconnection member 70, eliminating the need to install a housing that operably supports the disconnection member 70 on the child seat body 11. Therefore, by increasing the size of the connection release member 70 while suppressing the increase in size of the fixing unit 50, the connection release member 70 extending from the child seat body 11 is largely exposed from the child seat body 11 and the raised portion SA of the seat S. be able to. As a result, it becomes possible to easily hook a finger on the disconnection member 70 or to easily grasp the connection release member 70, and the operability of the connection release member 70 can be significantly improved.

Further, in the illustrated fixed unit 50, it is necessary to perform an operation such as moving the connection release member 70 to the front side while pushing the regulation release member 75 to the rear side. However, the deregulation member 75 has a deregulation operation unit 76 exposed forward from the decoupling member 70. Further, the connection release member 70 has an operation surface 72a facing the rear side. Therefore, while grasping the regulation release operation unit 76 and the operation surface 72a in the front-rear direction DX with one hand, the connection release member 70 and the regulation release member 75 can be moved forward along the front-rear direction DX, so that the operation can be performed. It can be simplified.

In this way, the connection release member 70 and the regulation release member 75 are moved to the front side in the front-rear direction DX. While the disengagement member 70 moves from the position shown in FIG. 14C to the position shown in FIG. 14D, the intermediate transmission member 85 and the disengagement operation member 65 also move in synchronization with the disengagement member 70. In particular, the release operating member 65 moves from the connection position shown in FIG. 12 to the release position shown in FIG. As a result, as shown in FIG. 11, the connecting member 62 is rotated to the open position shown in FIG. 11 by the urging force from the connecting member urging member 64, and the connecting tool 60 is connected to the anchor A. It will be released.

In the state of FIG. 14C, the operation restricting member 79 is located at the intermediate portion in the front-rear direction DX of the first elongated hole portion 56a of the restricting elongated hole 56 of the decoupling member 70. Therefore, from the state of FIG. 14C to the state of FIG. 14D, the disconnection member 70 can be moved to the front side in the front-rear direction DX with respect to the intermediate frame member 80.
