And extend the most upward with identical width, slope up in both sides near upper end
End, is thus formed about the shape gradually expanded for width in upper end.That is, the upper end of pod 50a
Corner 50b implement chamfered.It addition, the groove portion extended with same widths of pod 50a
Point be dimensioned to for halliard 4 through but the size that cannot pass through of the 4a that knots.
Therefore, as shown in (b) in Fig. 5, when the root of the 4a that knots of halliard 4 is inserted
When in the pod 50a of rope engaging portion 50 and the 4a that knots is arranged in the open end side of wireline reel 14,
Just can be by locking for halliard 4 so that it is do not fall off.This is because: the lower end side of halliard 4 because of
The weight of underbeam 6 and be tightened up, the 4a that therefore knots is engaged in pod 50a.Locking at this
Under state, owing to the overall dimensions of the 4a that knots is more than the width of pod 50a, therefore knot 4a not
Can come off from pod 50a.It addition, the root of the 4a that knots of halliard 4 is being inserted in pod
Time in 50a, owing to the upper end of pod 50a is formed with the corner 50b through chamfered, therefore hold
Easily insert.
As it has been described above, halliard 4 to be hung over the wire clips of the outer peripheral face standing up wireline reel 14
Determine in portion 50 and locking, just can easily carry out the replacing of halliard 4.Such as, in lifting
Rope 4 when the fracture of midway, for power halliard 4 being engaging in rope engaging portion 50, i.e. by
The pulling force that the weight of underbeam 6 causes disappears.Therefore, the 4a that will knot takes out from pod 50a,
Therefore easily can take off halliard 4 from wireline reel 14.
Afterwards, when being installed on wireline reel 14 by halliard 4, lower end is connected to underbeam 6
On halliard 4 the 4a that knots root insert rope engaging portion 50 pod 50a in and will knot
4a is locking.
Therefore, according to other examples of present embodiment, it is possible to easily change halliard 4.Separately
Outward, in the case of halliard 4 ruptures, if the upper end of rope engaging portion 50 is in downward
State, then halliard 4 will come off from rope engaging portion 50, is therefore made without lifting
The process that rope 4 is pulled down.Even if the upper end of rope engaging portion 50 is in state upward, due to
The root of 4a of knotting only exists in the state in the pod 50a being embedded in rope engaging portion 50, the most also can
The most easily from rope engaging portion 50, take off halliard 4.
It addition, the pod 50a of rope engaging portion 50 can also be following shape, it may be assumed that the width of groove
Along with becoming narrow gradually the most upward, and the corner 50b near upper end is carried out at chamfering
Reason.Now, unbroken under normal circumstances at halliard 4, it is possible to the root of the 4a that makes to knot is difficult to
Come off.And then, it is configured to vertical along being longitudinally formed with in rope engaging portion 50 in the above description
This structure of groove 50a but it also may replace this pod 50a, but fixed erectting the wire clips arranged
Horizontal groove or oblique groove is formed in portion 50.It addition, as the rope engaging portion of the second engaging portion
50 can also be arranged on the outer peripheral face of the second cylindrical portion 43 of lid 40.And then, can justify
The peripheral edge portion of ring flat-plate 44 forms the groove of similar pod 50a, and as the second engaging portion.
Above, embodiments of the present invention are illustrated, but the invention is not restricted to above-mentioned enforcement
Mode, it is possible to suitably changing without departing from the range of its purport.
Such as, in the present embodiment, to being applied to the lowering or hoisting gear of the present invention there are many pieces of leaves
Situation in the horizontal type louver of sheet is illustrated, but the lowering or hoisting gear of the present invention can be applied to
In the various shutters (solar radiation shielding apparatus) of Roman shade (rolling up curtain) or pleated curtain etc..
