PROBLEM TO BE SOLVED: To provide an electric tool which can easily prevent falling of an output shaft and a tip tool from an electric tool body with a simple configuration.SOLUTION: An electric tool comprising: a storage part which stores a hammer 47; and an anvil 5 which has an anvil body part 51 which is stored in the storage part and an installation part which extends outside the storage part via an opening of the storage part and can install a socket P, and which can be rotated by rotation of the hammer 47. The anvil body part 51 has: a first large diameter part 51B; a second large diameter part 51C; and a thin wall part 51D having a section orthogonal to an axial direction of the anvil body part 51 which has a section modulus smaller than a section modulus of any section of a tool holding part 53 and an extension part 54 orthogonal to the axial direction of the anvil body part 51. The storage part has a projection 84 which projects to a radial direction inner side of the anvil body part 51, and the projection 84 is positioned on a side opposite to the hammer 47 with respect to the anvil body part 51, and has a contact surface 84A which is opposite to the anvil body part 51 in a cross direction.SELECTED DRAWING: Figure 5 【課題】簡易な構成で電動工具本体からの出力軸及び先端工具の脱落を容易に防止可能な電動工具を提供する。【解決手段】ハンマ４７を収容する収容部と、収容部に収容されるアンビル本体部５１と、収容部の開口を介して収容部の外に延出しソケットＰを装着可能な装着部とを有しハンマ４７の回転によって回転可能なアンビル５と、を備え、アンビル本体部５１は、第１大径部５１Ｂ、第２大径部５１Ｃ、工具保持部５３及び延出部５４のアンビル本体部５１の軸方向に直交するいずれの断面の断面係数よりも断面係数の小さいアンビル本体部５１の軸方向に直交する断面を有する薄肉部５１Ｄを有し、収容部は、アンビル本体部５１の径方向内方に突出する突出部８４を有し、突出部８４は、アンビル本体部５１に関してハンマ４７とは反対側に位置し、前後方向においてアンビル本体部５１と対向する当接面８４Ａを有している。【選択図】図５
