周辺部までをシリンダケースカバが覆っていないため、
保護具としての機能を十分に果たしていなかった。Since the conventional cylinder case cover cannot be formed into a shape that can fit into the undercut portion of the cylinder case because it is formed of leather, the cylinder case cover cannot be formed during work. There is a problem in that the cylinder is misaligned, and accordingly, the outer peripheral portion of the cylinder case cannot be reliably gripped. That is,
There was a problem that work efficiency was lowered. Further, although each cylinder case cover is detachably fixed by using a button, the engaging method using the button is troublesome because it is difficult to engage the button in the engaging hole. Furthermore, the cylinder case cover does not cover the tool holding part that is the easiest to grip during work and the periphery of the fastening part that stops the cylinder case.
It did not fully function as protective equipment.
