とを結合したことを特徴とする安全弁装置。 A cylinder having a cylindrical shape, a mounting member for attaching the cylinder to a pressure vessel, a valve body provided airtightly and movably within the cylinder, a spring for biasing the valve body, and the cylinder. and a knob member attached to the upper end of the valve body, the valve body is controlled by the pressure in the pressure vessel introduced into the cylinder. The valve body moves against the biasing force of the spring and releases the pressure inside the pressure vessel from the pressure relief passage when the pressure inside the pressure vessel rises above a predetermined pressure. A fitting part that can be elastically deformed in the radial direction is formed at the upper end, and a fitting hole into which the fitting part fits is formed at the lower end of the knob member. An engaging portion is formed inside, and an engaging portion that engages with the engaging portion is formed in the fitting portion, and the fitting portion of the valve body is fitted into the fitting hole of the knob member. A safety valve device characterized in that the engaging portion of the fitting portion elastically engages with the engaging portion of the fitting hole to connect the valve body and the knob member.
