Power slider
A power slider includes a lower rail and an upper rail which are engaged with each other so as to be mutually slidable along each other, a screw rod which is rotatably supported on one of the lower rail and the upper rail, a feed nut which is supported on the other of the lower rail and the upper rail and is screw-engaged with the screw rod, and a gearbox which is supported on the one of the lower rail and the upper rail via a holder and which rotatably drives the screw rod. The gearbox is provided with a mounting bolt through-hole and is supported by the holder via a mounting bolt that is inserted through the mounting bolt through-hole. A resilient member is positioned in a space defined between the mounting bolt through-hole of the gearbox and the mounting bolt.
1. A power slider comprising:
a lower rail and an upper rail which are engaged with each other so as to be mutually slidable along each other;
a screw rod which is rotatably supported on one of
said lower rail and said upper rail;
a feed nut which is supported on the other of said lower rail and said upper rail and is screw-engaged with said screw rod; and
a gearbox which is supported on said one of said lower
rail and said upper rail via a holder and which rotatably drives said screw rod,
wherein said gearbox is provided with a mounting bolt through-hole and is supported by said holder via a mounting bolt that is inserted through said mounting bolt through-hole, and
wherein a resilient member is positioned in a space defined between an inner surface of said mounting bolt through-hole of said gearbox and a part of an outer peripheral surface of said mounting bolt, said part being positioned inside said mounting bolt through-hole.
2. The power slider according to claim 1 , wherein said resilient member is provided with a facing wall which is positioned in between mutually facing surfaces of said holder and said gearbox.
3. The power slider according to claim 2 , wherein said mounting bolt through-hole of said gearbox extends in a direction parallel to the axis of said screw rod, and
wherein a pair of said facing walls of said resilient member are separated in a direction parallel to the axis of the screw rod and are each positioned between the mutually facing surfaces of said holder and said gearbox so that said gearbox is sandwiched between said pair of mutually facing
walls.
4. The power slider according to claim 1 , wherein said holder comprises a U-shaped section defined by a pair of mutually facing walls and a connecting portion which connects said pair of mutually facing walls,
wherein said connecting portion is provided with an insertion groove, and
wherein said resilient member is provided with a neck portion which is fitted into said insertion groove, and a fall-out prevention portion which is connected to said
connecting portion via said neck portion.
5. A power slider comprising:
a screw rod supporting rail which supports a screw rod;
a feed nut supporting rail which supports a feed nut that is screw-engaged with said screw rod, said screw rod supporting rail and said feed nut supporting rail being engaged with each other so as to be relatively slidable in length-wise directions thereof; and
a gearbox which is supported on said screw rod supporting rail to drive said screw rod;
wherein said gearbox is provided with amounting bolt through-hole, through which a mounting bolt is inserted to
mount said gearbox onto said screw rod supporting rail, and
wherein a resilient member is positioned in an annular space defined between an inner surface of said mounting bolt through-hole of said gearbox and a part of an outer peripheral surface of said mounting bolt, said part being positioned inside said mounting bolt through-hole.
