the air intake apparatus for the internal combustion eigne, wherein
on an end portion of one of said rotating shaft and said drive shaft, a sphere portion and a projection portion are provided;
on an end portion of one of said rotating shaft and said drive shaft, a cup portion and a faucet portion are provided; and
said sphere portion is inserted into said cup portion and further said projection portion is engaged with said faucet portion,
thereby a universal joint is formed.
2. An air intake apparatus for an internal combustion engine according to claim 1, wherein
an inner portion of said faucet portion is formed with a dent shape, and further an outer portion of said projection portion is formed with a raise portion.
3. An air intake apparatus for an internal combustion engine according to claim 1, wherein
said drive shaft is arranged in a resin housing, and to said drive shaft a ball bearing member is fixed; and
to said resin housing a part of said ball bearing member is stopped, and further said ball bearing member is fixed to said resin housing by a stopper ring having a spring operation.
4. An air intake apparatus for an internal combustion engine, wherein
a drive shaft is arranged in a resin housing;
a shaft of an opening and closing valve and said drive shaft are connected with a universal joint construction;
to said drive shaft a ball bearing member is fixed; and
to said resin housing a part of said ball bearing member is stopped, and further said ball bearing member is fixed to said resin housing by a stopper ring having a spring operation.
5. In an air intake apparatus for an internal combustion engine comprising a rotating shaft which is installed to an opening and closing valve for shielding the air intake supplied to an internal combustion engine as one body, a drive shaft for rotating said rotating shaft, and a connection portion for connecting said rotating shaft and said drive shaft and for transmitting a move from said drive shaft to said rotating shaft,
the air intake apparatus for the internal combustion eigne, wherein
on an end portion of said rotating shaft, a sphere portion and a projection portion are provided;
on an end portion of said drive shaft, a cup portion and a faucet portion are provided; and
said sphere portion is inserted into said cup portion and further said projection portion is engaged with said faucet portion,
thereby a universal joint is formed.
6. In an air intake apparatus for an internal combustion engine comprising a rotating shaft which is installed to an opening and closing valve for shielding the air intake supplied to an internal combustion engine as one body, a drive shaft for rotating said rotating shaft, and a connection portion for connecting said rotating shaft and said drive shaft and for transmitting a move from said drive shaft to said rotating shaft,
the air intake apparatus for the internal combustion eigne, wherein
on an end portion of said drive shaft, a sphere portion and a projection portion are provided;
on an end portion of said rotating shaft, a cup portion and a faucet portion are provided; and
said sphere portion is inserted into said cup portion and further said projection portion is engaged with said faucet portion,
thereby a universal joint is formed.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An anchor system in combination with a floating decoy, the combination comprising:
the floating decoy simulating a waterfowl;
a tether attached to the floating decoy at a first end, the tether having a second end located distally from the first end, the tether having an intermediate portion between the first and second ends;
a weight mounted on the tether and slidable to a position substantially adjacent to the floating decoy, the weight defining a bore extending axially therethrough which slidably receives the tether;
a first stop mounted near the first end and adjacent to the floating decoy adapted to prevent the weight from damaging the decoy, the first stop having a diameter larger than a diameter of the bore;
a first loop formed in the tether at the first end, the first loop formed by the first end being directed toward the second end and then secured in generally parallel relation to the intermediate portion of the tether by the first stop;
a second loop formed in the tether at the second end, the second loop formed by the second end being directed toward the first end and then secured in generally parallel relation to the intermediate portion of the tether by a second stop, the second stop is located along the tether between the second loop and the weight, the second stop having a diameter larger than the diameter of the bore, the weight being slidable between the first and second stops; and
a rotatable fastener mounted to the first end at the first loop, the tether is releasably attached to the floating decoy by the rotatable fastener, the rotatable fastener has a joint that allows free rotation of the tether relative to the floating decoy, the fastener includes a clip that releasably attaches the fastener to the floating decoy.
2. The anchor system of claim 1, wherein the tether has a length of at least 12 inches.
