Abstract
A damper includes a piston provided with a rod, and a cylinder storing the piston, and generates a braking force by a movement or relative movement of the piston. The cylinder is provided with width-side wall portions and thickness-side wall portions, and a shape in a cross section of the cylinder in a direction orthogonal to a moving direction of the piston is flat. The cylinder has a connection portion on an open side thereof, and the connection portion bridges the width-side wall portions.
Claims11
A damper comprising:
- a piston provided with a rod at one end thereof, the rod having an elongated hole therein extending along a moving direction of the piston,
- a cylinder storing the piston, and generating a braking force by a movement or relative movement of the piston, the cylinder having an opening at one side, a closed end at a side opposite to the opening, width-side wall portions and thickness-side wall portions connecting the width-side wall portion to have substantially a flat rectangular shape in a cross section, the piston with the rod moving in a direction parallel to the width-side wall portions and the thickness-side wall portions, and
- a connection portion bridging the width-side wall portions, the connection portion being formed adjacent the opening and passing through the elongated hole of the rod to cross the opening so that the rod extends outwardly from the cylinder through the opening, the connecting portion extending perpendicular to the width-side wall portions at a position away from the thickness-side wall portions to connect the width-side wall portions.
A damper consisting essentially of:
- a piston provided with a rod at one end thereof, the rod having an elongated hole therein extending along a moving direction of the piston,
- a cylinder storing the piston, and generating a braking force by a movement or relative movement of the piston, the cylinder having an opening at one side, a closed end at a side opposite to the opening, width-side wall portions and thickness-side wall portions connecting the width-side wall portion to have substantially a rectangular shape in a cross section, the piston moving in a direction parallel to the width-side wall portions and the thickness-side wall portions, and
