Abstract
Provided are a shock absorber and a bracket which are improved in attachment rigidity. A cylindrical portion is shaped by press-forming first and second holes in sheet material (flat plate) and then curving the sheet material into a tube, in which a bridge portion is formed between the first and second holes. The bracket is thus improved to have higher formability as compared to conventional brackets which are not provided with a bridge portion. This improves the accuracy (cylindricity, in particular) of the cylindrical portion. It is then possible to improve the shock absorber in attachment rigidity against a lateral force to the anteroposterior direction of a vehicle in a situation where the bracket is used to attach the shock absorber to the knuckle.
