Abstract
A racket for playing tennis or similar ball games having a straight bar type stem part which continues to an annular ball hitting part. A hole is provided in the stem part in which a vibration absorbing member is stored. Said vibration absorbing member comprises a buffer layer made of a gel material and a mass member supported by this buffer layer. The buffer layer is fixed so that it can be deformed in said hole and said mass member is supported so that it does not contact the internal surface of the hole. Said vibration absorbing member can be put in an outer casing and inserted into the hole. In this case, the buffer layer is deformed in the outer casing and the mass member is held so that it does not contact the internal surface of the outer casing.
