密閉装置。[Scope of Claim for Utility Model Registration] (1) A smoke inlet is opened on the circumferential surface of the body on the surface side of the base plate disposed inside the body, and smoke is introduced to the front side of the base plate through the smoke inlet. In a smoke detector whose presence or absence is determined by a circuit section mounted on the back side of a board, there is a ring-shaped ring that surrounds the entire circumference of the circuit section between the periphery of the back side of the board and the inner circumferential surface of the device body. A first gasket is sandwiched therein, and a terminal for connecting the circuit section to an external circuit is protruded from a portion surrounded by the first gasket on the back surface of the substrate and connected by solder on the back surface of the substrate. , the terminal is pulled out from a terminal extraction hole provided in the container body through a second gasket sandwiched between the inner circumferential surface of the container body and the substrate,
On the end surface of the second packing on the substrate side,
A sealing device for a smoke detector, in which a tapered recess is formed whose diameter decreases as the distance from the end face increases in the protruding direction of the terminal, and solder for connecting the terminal is housed in the recess. (2) The sealing device for a smoke detector according to claim 1, wherein the first gasket and the second gasket are integrally formed.
