A valve body 8 having a valve shaft 7 on the hot water side valve body 5 and the water side valve body 6 corresponds to the hot water side valve seat 3 and the water side valve seat 4 from the outside of the cylinder 2, respectively, and the valve shaft 7 is attached to the cylinder 2. A screw 1 is secured to a disk-shaped pressure receiving member 9 extending into the cylinder 2 and slidably inserted into the cylinder 2.
0, and the hot water chamber 11 is located between the hot water side valve body 5 and the pressure receiving member 9.
A water chamber 12 is formed between the water side valve body 6 and the pressure receiving member 9. When one valve body (5 or 6) approaches the corresponding valve seat (33 or 4) due to the sliding of the pressure receiving member 9 due to a change in the pressure balance between the water chamber 11 and the water chamber 12, the other valve body (5 or 6) approaches its corresponding valve seat (33 or 4). The valve body (5 or 6) moves in a direction away from the corresponding valve seat (3 or 4.) to always equalize the supply pressures of hot water and water.

吐出される混合水温度が変動する。(For example, Japanese Unexamined Patent Publication No. 56-90175) Problems to be Solved by the Invention However, in the above configuration, the guide portion in the sliding direction of the valve body 8 and the pressure receiving member 9 is located between the pressure receiving member 9 and the cylinder 2. The pressure receiving member 9 is only supported by contact alone.
Backlash is likely to occur in the radial direction with the fulcrum being the fulcrum, and the play may impede smooth sliding and impair the pressure regulating function. Furthermore, even when the pressure receiving member 90 is widened to be able to be guided, increasing the contact area with the cylinder 2 not only increases the sliding frictional resistance but also increases the sliding part including the valve body 9. The increased weight makes it impossible to respond to minute pressure imbalances, and therefore the temperature of the mixed water discharged from the hot water mixing device behind the automatic pressure regulating valve fluctuates.
