Abstract: A cable winding device is provided, which is for a flexible flat cable routed to a sliding seat slidably supported allowing for forward and backward movement in a longitudinal direction of a fixed rail; a first side end portion of the cable being fixed to an end of the fixed rail corresponding to a first rail end portion; the device including a winding housing portion inside which a second side end portion of the cable is fixed; the winding portion being fixed to a movable body supporting the seat and configured to slide in a forward and backward direction relative to the fixed rail; in a case where the winding portion moves in a forward (or backward) movement direction toward (or away from) the first rail end portion, the cable is wound in the winding portion (or is fed out along the fixed rail from the winding portion).

Abstract: Object: It is desirable to provide a waterproof connection structure, a connection structure body, and a partition member that can easily and reliably prevent water penetration. Resolution Means: The waterproof connecting portion (1A) of a connection structure body (1) includes an FFC (30) formed by sandwiching a plurality of flat conductors (41) arranged in parallel in a width direction in a sheet-like insulating covering, a plurality of insulated wires (40) each obtained by covering a conductor (41) with an insulating covering (42), a plurality of WF terminals (20) that are arranged in parallel in the width direction and connect the flat conductors (41) and the conductors (41), a terminal holder (10) that partitions the WF terminals (20) in an insulating manner, and a butyl sheet (50) that integrally covers the plurality of WF terminals (20) partitioned by the terminal holder (10) and the terminal holder (10), and has waterproofing properties, insulating properties, and stretching properties.
