カム片による緊締が不安定となる惧れがある。 In addition, due to the fitting play of the hook with respect to the expanded end of the upper half ring including the locking curved edge and the axial play of the cam piece pivotally supported by the hook, the gap between the locking curved edge and the cam piece is There is a possibility that considerable displacement in the longitudinal direction may occur, and as a result, the tightening by the cam piece may become unstable.
本考案は上記全く異質の問題点に対処しうる単
一、かつ簡素な手段を創出することを解決すべき
技術課題とするものである。 The technical problem to be solved by the present invention is to create a single and simple means capable of dealing with the completely different problems mentioned above.

a, 12b and two support rods 14, 14 that interconnect them. On the cylinder holder 10, there is one or more annular straps 28 for mounting and tightening the LPG cylinder 26. A hook 30 and a cam piece 32 corresponding to this are provided. Although not clearly shown in the figure, the cylinder holder 10
is pivotably supported on one rear column 18a of the head guard as in the conventional device, and is pivotably supported on the other rear column 18a.
The pivot end is locked by 8b. The above-mentioned rotation of the cylinder holder 10 causes the LPG cylinder 26 to open when the engine hood 50 is opened rearward.
However, the cylinder holder 10 is not necessarily placed in the rear column 18.
It is not limited to those attached to the seats 52a and 18b, but may be fixedly attached to the weight 54, for example, via a bracket or the like, without interfering with the seat 52.

されていることである。 Figure 1 shows the support rods 1 that constitute the cylinder holder 10
4 and 14 are enlarged views of the cylinder tightening means disposed on the cylinders 4 and 14. In FIG. 1, the lower half ring 28b of the annular band 28 is fixed on the support rods 14, 14 by welding or the like, and the paired upper half ring 28a is attached to the lower half ring via a hinge member 29. 28b, and is expandable in a plane orthogonal to the support rod 14. A bracket 31 is attached to one support rod 14.
A hook 30 is pivotally supported through the upper half ring 28, and the hook portion 30a, which is bent into a substantially rectangular shape,
The upper half ring 28 is rotated in the same plane as the development plane of a.
It can be fitted into the expanded end portion including the locking curved edge 28c extending upwardly in the direction a. The above hook part 30
A collar 32a fixed to the middle part of the cam piece 32 is loosely fitted to the upper side of the figure a, and the cam piece 32 rotates the hook 30 independently within the same rotation plane with the upper side of the hook part 30a as a pivot. A round bar-shaped engager 32 is movable and fixed to the lower end thereof.
b engages with the locking curved edge 28c, and the cam piece 32
Due to the cam action accompanying the rotation of the locking curved edge 28
c can be pressed downward. Note that the illustrated upper edge of the cam piece 32 is bent at a substantially right angle because its bent end 32c is connected to the upper half ring 28a.
Although not shown, the hook portion 30a is configured to interfere with the hook portion 30 to limit excessive rotation of the cam piece 32.Also, although not shown, the hook portion 30a is provided with a length that is adjusted relative to the base of the hook portion 30, for example, via an adjustment screw. Can be configured to be adjustable. A particularly novel structure of the present invention is that stop plates 33, 33 that cover both sides of the deployed end including the locking curved edge 28c are attached to both end surfaces of the deployed end.

28cと確実に整合させることができる。 Therefore, in the device of the present invention, the LPG cylinder 26 is placed on the lower half ring 28b of the upper half ring 28a of the annular band 28 in an open state, and the upper half ring 28a is placed on the LPG cylinder 26. The hook 30 and the cam piece 3 are in a connected relationship after being reversely crowned.
2, the LPG cylinder 26 is tightened through the upper half ring 28a, but the hook 3
When the hook portion 30a of 0 faces the upper half ring 28c, the engaging member 32b is generated in the fitting clearance between the hook portion 30a and the locking curved edge 28c, and at the respective pivot points of the hook portion 30 and the cam piece 32. The locking curved edge 28c is skillfully guided by the stop plates 33, 33 and prevented from slipping off, without being bothered by longitudinal positional deviation with respect to the locking curved edge 28c, which appears as a sum of axial play. 28c.

とができる。 The tightening force of the LPG cylinder 26 applied via the locking curved edge 28c of the upper half ring 28a is applied until the pivot shaft of the cam piece 32 and the engager 32 are aligned with the pivot shaft of the hook 30. When the cam piece 32 is rotated to the point position, the cam piece 32 reaches its maximum value, and rotation beyond this point is limited by the interference of the bent end 32c of the cam piece 32 with the upper half ring 28a. The reverse rotation of the piece 32 is prevented by the elastic reaction force of the upper half ring 28a, and a stable tightened state is maintained.
The expansion end is reinforced by the retaining plates 33, 33 due to the continuation of such tightening force.
It can sufficiently withstand the load applied to 8c.

維持することができる。[Effects of the invention] As detailed above, the present invention provides a stop plate that covers both sides of the deployed end including the locking curved edge extending on the upper half ring of the annular band. Since the expanded end of the upper half ring that extends from the annular part to the locking curved edge is reinforced by the attachment of the stopper plate, the bending of the locking curved edge is prevented. Since it can sufficiently withstand the tightening force acting in the direction of extension, the risk of the cylinder falling off due to deformation of the locking curved edge can be eliminated, contributing to longer life of the device. The lower end of the cam piece is guided and interfered with to prevent longitudinal displacement of the cam piece relative to the locking curved edge, so the lower end of the cam piece is reliably aligned with the locking curved edge, resulting in a stable tightening condition. can be achieved and maintained.
