  • Publication number: 20240133401
    Abstract: A flat transmission device includes a belt-shaped unit and a clamp device. The clamp device includes a main clamp member that covers a part of an end of the belt-shaped unit in the width direction including a side edge of the belt-shaped unit on a first side in the width direction, and an auxiliary clamp member that covers a part of the end of the belt-shaped unit in the width direction including a side edge of the belt-shaped unit on a second side in the width direction. The main clamp member and the auxiliary clamp member move relative to each other while partially overlapping with each other in the width direction, thereby cooperatively entirely covering the end of the belt-shaped unit in the width direction.

  • Publication number: 20240102597
    Abstract: A long object guiding device includes a long tubular member and is configured to guide a long object inserted through the tubular member while protecting, with the tubular member, the long object in correspondence with displacement of the tubular member. The tubular member has a long sheet shape in an unfolded state. A longitudinal direction of the tubular member intersects a width direction. A first joint portion is disposed on one side edge of the tubular member in the width direction to extend in the longitudinal direction. A second joint portion is disposed on an other side edge of the tubular member in the width direction to extend in the longitudinal direction. At least one end of the tubular member, in the longitudinal direction, has a passage portion that allows for passage of an end of the long object.

  • Patent number: 10622760
    Abstract: A lever-type connector (F) includes a housing (10) formed with support shafts (26) and rotation restricting portions (20F, 20R). A lever (30) includes plate-like arms (31) and is rotatable between an initial position where the lever waits at the start of connection to a mating connector (M) and a connection position where the connection to the mating connector (M) is completed. The lever (30) is mounted by fitting bearing holes (34) of the arms (31) to the support shafts (26). Reverse rotation restricting projections (45) project from surfaces of the arms (31) facing the housing (10) toward the housing (10) and are configured to be locked to the rotation restricting portions (20F, 20R) to restrict rotation of the lever (30) at the initial position toward a side opposite to the connection position.
