PROBLEM TO BE SOLVED: To provide a diaphragm valve structure and a solenoid valve in which a stress generated at a diaphragm part can be reduced and durability of the diaphragm can be improved.SOLUTION: A diaphragm valve structure 30 comprises a column-shaped valve body part 4a abutted against or spaced apart from a valve seat 2c; a diaphragm part 4b extended outward from the valve body 4a and arranged; a diaphragm 4 including an outer edge part 4c arranged along an outer edge of the diaphragm part 4b to be thick and fixed between a valve body 2 and a stuffing 7; a shaft member 5 integrally arranged at the valve body part 4a to protrude from the center of a counter valve seat side end surface 4e of the valve body part 4a, having the extremity end arranged inside the valve body part 4a and adhered to the valve body part 4a so as to transmit driving force to the valve body part 4a. At least a portion of the counter valve seat side part from a position where the diaphragm part 4b is connected to the valve body 4a in the portions where the valve body part 4a and the shaft member 5 are contacted to each other is set to be non-adhered. |
