Smoke screen generator

A smoke screen generator comprising a cylindrical housing, an igniter and a smoke screen generating agent which are accommodated in the cylindrical housing,

• a first closure including an igniter and closing a first end opening of the cylindrical housing,
• a second closure having a smoke screen source discharge port and closing a second end opening of the cylindrical housing on an opposite side in an axial direction to the first end opening,
• the first closure having a discharge hole for discharging an ignition product which is generated at the time of actuation of the igniter,
• a porous cylindrical body being arranged between a surface of the first closure where the discharge hole for the ignition product is not provided and the smoke screen source discharge port of the second closure,
• a space between an inner circumferential wall surface of the cylindrical housing and the porous cylindrical body being a smoke screen generating agent-accommodating chamber which accommodates the smoke screen generating agent, and the discharge hole for the ignition product facing the smoke screen generating agent-accommodating chamber, and
• at the time of actuation of the igniter, the smoke screen generating agent in the smoke screen generating agent-accommodating chamber being ignited and burned to generate a smoke screen source, the smoke screen source moving through the inside of the porous cylindrical body, passing through the smoke screen source discharge port, and thereafter being discharged to the outside to generate a smoke screen.
