Title:
VALVE DEVICE
Document Type and Number:
Japanese Patent JP2015059491
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To surely pressurize and hold a valve body between first and second slit shaft parts by making the slit shaft part easy to bend without causing deterioration of assembly accuracy.SOLUTION: A valve body 5 is fixed at a shaft 4 by a screw 15 while being inserted in a slit hole 14. A separation part α is provided only at the first slit shaft part 4a, out of first and second slit shaft parts 4a, 4b opposing to each other via the slit hole 14. Thereby, rigidity of the first slit shaft part 4a is decreased and the first slit shaft part 4a becomes easy to bend, so that the valve body 5 can be pressurized and held surely between the first and the second slit shaft parts 4a, 4b. Also, different from this invention, when separation parts α is provided both on the first and the second slit shaft parts 4a, 4b, failure occurs such as axial deviation of the shaft 4 and deterioration of assembly accuracy of the valve body 5. As opposed to this, the separation part α is provided only at the first slit shaft part 4a in this invention, so that the shaft 4 does not axially deviate and deterioration of the assembly accuracy of the valve body 5 does not occur, either.
