## Abstract

A hollow component made of thin sheet metal members is described, along with a method of manufacturing such hollow component. The method involves applying a flow drilling process on one sheet metal member of a pair of sheet metal members having a gap G between them to form a first collar part. A flow drilling process is applied on the other sheet metal member of the pair to form a second collar part as well as to cause an inner tip of the second collar part to fuse with an inner tip of the first collar part. A cylindrical connection member is formed to strengthen a flat sheet metal members.

## Claims

### Claim 1

A hollow component formed by joining and connecting together a first sheet metal member and a second sheet metal member in a process comprising:
forming a first collar part by applying a flow drilling process inwardly from an outside of said first sheet metal member;
forming a second collar part by applying the flow drilling process inwardly from an outside of the said second sheet metal member;
fusing together a first inner tip of the first collar part and a second inner tip of the second collar part, when the second collar part is formed, to form a cylindrical connection member that connects said first sheet metal member and second sheet metal member.

### Claim 2 (depends on 1)

The hollow component according to claim 1, where said hollow component is a brake pedal formed to connect an end of a rod with a master vac and an other end of the rod with a protruding end of a pin member that is inserted into the cylindrical connection member.
