(54) Foldable cross wrench


(57) The foldable cross wrench having four wrench members (20) pivoted to a coupling member (10) can be stretched into a cross shape, and secured on its stretched position by a cap member (40) which is provided with keys (43) to engage with key ways (17) on the wrench member (20). When the wrench is not used, the cap member is rotated to a position where the keys (43) are not engaged with the key ways (17) on wrench members (20) so that the wrench members (20) can be pivoted to a folded position.
