A baffle plate (, partition member) is manufactured by being integrally formed of a single material including flexible or pliable NBR (nitrile rubber), and a projection () formed on an abutment surface (B) of the baffle plate () is fitted into a recess () in a reduced-diameter portion () of an intermediate tube (). Thus, when the intermediate tube () fitted with the baffle plate () is assembled into an outer tube, the sheet-shaped baffle plate () can be prevented from rotating about a connecting pipe (), and it is possible to improve the productivity and assembleability of the shock absorber.

Shock absorber and manufacturing method therefor

A shock absorber includes a reservoir between a cylinder and an outer tube, in which hydraulic liquid and gas are sealed; a middle tube between the cylinder and the outer tube; a connecting pipe in the lateral wall of the middle tube, which includes a tip end extending toward the outside of the outer tube; an opening in the outer tube, allowing hydraulic liquid to flow from the outside of the outer tube into the reservoir through the outer side of the connecting pipe; and a partition member in the reservoir, which includes a partition wall that configured to regulate hydraulic liquid's upward flow from the opening in the reservoir. The partition member is made of flexible resin or rubber, provided with a fitting hole, and fitted to the connecting pipe with interference with the connecting pipe inserted through the hole.
