摘要：
A spirit level comprises a body member containing a levelling tube, in which the base of the body member has a width greater than the width of the body member in any other plane parallel with the base. Preferably, the body member is triangular in cross section and may comprise three elongate wing or flange members extending radially from a central hub region. The body member may have axilly-extending, for example telescopic, end members.
