bolts

11, 12 together. Note that the elongated sheet shape of the connector includes a case where the connector extends straight in the length direction of the connector and a case where the connector is slightly bent in the length direction of the connector when viewed in the thickness direction of the connector. In a first embodiment of the invention, shown in fig. 6, the connection 13 is configured: the link member extends straight in the length direction of the link member (left-right direction in fig. 6) when viewed in the thickness direction of the link member 13 (up-down direction in fig. 6). Two holes through which the two

bolts

11, 12 pass are provided at both end sections of the connecting member 13, and the both end sections of the connecting member 13 provided with the holes are on the same level as the central section of the connecting member 13 (i.e., the connecting member 13 is flat when viewed in the width direction of the connecting member, i.e., the direction of the paper surface in fig. 6). The

bolts

11, 12 each pass through a corresponding hole in the connecting piece 13 and are fixed together with the connecting piece 13 by fixing means such as welding or riveting. In particular, the

bolts

11, 12 pass through holes in the connecting member 13 so that the heads of the

bolts
