Abstract: A ratchet-type spanner includes a handle and a box end extended from the handle and having a hole. A slant hole is defined in a web between the handle and the box end and communicated with the hole of the box end. A ratchet gear includes an inner periphery for driving a fastener. The ratchet gear is rotatably mounted in the hole of the box end. A pawl is mounted in the slant hole and includes a first end with teeth for releasably engaging with teeth of the ratchet gear. A plug is securely mounted in the slant hole by force-fitting engagement with an inner periphery defining the slant hole. An elastic member is mounted in the slant hole and has a first end attached to the second end of the pawl and a second end attached to the plug for biasing the pawl to engage with the ratchet gear. The first end of the pawl includes a beveled face that faces the inner periphery of the slant hole.
