Embodiment Construction

[0034] Below, based on Figure 1 ~ Figure 13 , Describes a typical implementation of the present invention. The damper of the present embodiment generates a braking force against the movement or relative movement of the piston P constituting its structure, and is typically combined with an article provided with a movable part (not shown) that is a braking target and is used for The movement of the braking object acts on the braking force, so that the movement of the braking object becomes slow, high-quality, and restricted, so as not to suddenly accelerate.

[0035] The damper is composed of a piston P provided with a rod 1 and a cylinder S that houses the piston P. Typically, the damper directly or indirectly connects any one of the rod 1 and the cylinder S to the side of the brake object, and directly or indirectly connects the other of them to the place where the brake object can move. The supported side is thus combined with the article to be braked.

[0036] The cylinder S h...

Abstract

The present invention provides a damper comprising a piston including a rod and a cylinder for accommodating the piston, and generates a braking force by movement or relative movement of the piston. The cylinder is configured such that it has a wide side wall and a thick side wall, and has a flat cross-sectional shape in a direction perpendicular to the moving direction of the piston, and has a cross-section extending between the wide side walls on its open side. the connection part.

Description

Technical field [0001] The present invention relates to an improvement of a damper that generates braking force through the operation of a piston. Background technique [0002] In an air damper device formed of a cylindrical rod body with the inner end of the rod as the piston part and a cylindrical cylinder that can reciprocately house the rod body, there is a technology in which the rod body is provided in the rod body. It has a groove penetrating in the diameter direction, and a pin body penetrating the groove is provided on the open end side of the cylinder to prevent the rod from falling off the cylinder (see Patent Document 1, Figure 7 , Figure 8 ). [0003] In this Patent Document 1, the pin body has both ends crimped into the through hole provided in the cylinder body to be combined with the cylinder body, and the pin body does not have a function other than preventing the rod body from falling off.
