A wrench comprises a handle and a head extended from the handle. A web is defined between the handle and the head. The head includes a compartment in which a drive member is rotatably received. The web includes a transverse through-hole having an intermediate portion communicated with the compartment. A cavity is defined in the web and communicated with the transverse through-hole. A switch member is mounted in the cavity and rotatable relative to the handle between two positions corresponding to two opposite ratcheting directions of the handle. A pawl is slidably mounted in the transverse through-hole for engaging with the drive member. The pawl remains in the transverse through-hole during operation.
