Document Type and Number:
Japanese Patent JP7290050
Kind Code:

Abstract:
To reliably prevent wrong operation using an inexpensive jig having a simple structure.SOLUTION: In a slow leak valve 202 that is operated by inserting an operation member into a hole part 400 for operation and rotating the operation member around an insertion direction of the operation member, in order to prevent wrong operation, a wrong operation preventive tool 500, which is not operated even when it is inserted into the hole part 400 and rotated, is inserted into the hole part 400 when the slow leak valve 202 is not operated, and then a tip is brought into contact with the bottom part of the hole part 400. At that time, the tip of the wrong operation preventive tool 500 is projected from the hole part 400 so that a length in the insertion direction into the hole part 400 is longer than a depth of the hole part 400. The wrong operation preventive tool 500 uses an elastic member or the like.SELECTED DRAWING: Figure 6
