Abstract

There is provided a curtain opening/closing device whose number of parts is reduced, which is lightened, whose safety and durability are improved, whose installation space is reduced, whose appearance is improved and which can be installed freely along a curved surface, and a vehicle carrying the curtain opening/closing device. The curtain opening/closing device comprises a spiral long coil member, a movable member capable of moving within the long coil member, a rail member rotably and loosely fitting the long coil member and having a slit continuous in a longitudinal direction and a rotational driving section fixed at one end of the rail member and rotating and driving the long coil member. The movable member is inserted within the long coil member so as to be movable in the longitudinal direction.

a movable member connected with a curtain and which is guided reciprocatively;
and
a reciprocative driving means for guiding and driving the movable member, wherein said reciprocative driving means includes:
a spiral long coil member;
a rail member which encloses said long coil member such that the spiral long coil member is able to rotate therein, the rail member having a slit continuous in a longitudinal direction;
a rotational driving section that is fixed to one end of the rail member and that rotates and drives said long coil member;
a movable body inserted within an inside of said long coil member and said movable member, the movable body being movable in the longitudinal direction;
and
