<P>PROBLEM TO BE SOLVED: To enhance dimensional accuracy of a passing through part 11 of fluid formed in an inside deep part as much as possible while constituting at least the inside deep part 10 of a cylinder 1 constituting a damper device of synthetic resin. <P>SOLUTION: The damper device has the cylinder 1 and a piston 2 braking the movement or the relative movement of an object to be braked by linking the object to be braked one of the side of the cylinder and the piston. The inside deep part 10 facing the piston 2 in the cylinder 1 is constituted of the closing member 15 of synthetic resin attached to an end of the cylindrical body 13 constituting the cylinder 1. The closing member 15 has the passing through part 11 of fluid and the braking force variable member 151 moved in a direction hindering the passing by fluid passing through the passing through part 11 when the piston 2 in the direction leaving from the inside deep part 10 moves (moves forward). <P>COPYRIGHT: (C)2012,JPO&INPIT |
