Safety valve and discharge direction regulation member

A safety valve installed in a fluid apparatus including a path for fluid thereinside and is provided with a path for discharge branching from the path for fluid, comprising:

• a main body attached to an open end of the path for discharge of the fluid apparatus, in which an inflow path communicating with the path for discharge and a discharge path allowing the inflow path to communicate with the outside are formed;
• and
• a blocking member that blocks the flow of fluid from the inflow path to a discharge path,
• wherein the inflow path is connected to an abutting portion abutting on a sealing part formed at a tip end part of the blocking member to thereby block the flow of fluid and an open portion having a larger diameter than the abutting portion,
• the open portion communicates with the discharge path and forms an attachment portion for a pressing cap biasing the sealing part of the blocking member toward the abutting portion,
• a fusible alloy is disposed between the blocking member and the pressing cap, and a reservoir part that reserves the fused fusible alloy is formed at least in one of the blocking member and the pressing cap, and
• a plurality of porous plates punched positions of which do not overlap with each other are arranged between the reservoir part and the fusible alloy.
