Damper device

A damper device comprising:

• a cylinder body, and
• a piston body, in which at least one end of either the cylinder body or the piston body is adapted to be linked to an object to be braked to brake a relative movement or a movement of the object to be braked,
• wherein the cylinder body includes a blocking member made of a synthetic resin at a deep inner section opposing the piston body, the blocking member being formed separately from the cylinder body and installed in one end of a tubular-shaped body forming the cylinder body, and
• wherein the blocking member has a fluid passage section and a braking force variable member moved in the fluid passage section, the braking force variable member holding passage of a fluid passing through the fluid passage section at a time of a movement of the piston body in a direction leaving from the deep inner section.
