To provide a receiving device of a vibration hammer which can cope with a case where a work place is narrow by making the vibration hammer fall down in a planned direction when making the vibration hammer in a fallen-down posture when not used, and which can make a connection state of a chuck portion of the vibration hammer and the receiving device rigid.SOLUTION: A receiving device of a vibration hammer comprises: a chucking base 1 to which a chuck portion of a vibration hammer is connected; and a receiving base 2 including a receiving recessed portion 22 provided at a side portion of the chucking base 1 and receiving a rotation shaft 16. A center of gravity of the vibration hammer is positioned at one side with respect to a line connecting the receiving recessed portion 22 of the receiving base 2 with a ground surface. The vibration hammer rotates at a side where the center of gravity exists in a ground surface direction to be in a fallen-down state, and a standing state and the fallen-down state are switched by rotating the rotation shaft 16 in a reverse direction, with the rotation shaft 16 as a rotation center.SELECTED DRAWING: Figure 1 【課題】バイブロハンマを不使用時に横倒し姿勢にする際に、予定されている方向に倒れるようにして、作業場所が狭い場合にも対応できるようにし、バイブロハンマのチャック部と受け装置との結合状態を強固にすることが可能なバイブロハンマの受け装置を提供する。【解決手段】バイブロハンマのチャック部が結合されるチャッキング台１と、チャッキング台１の側部に設けられた回転軸１６を受ける受け凹部２２を有する受け台２とを備え、バイブロハンマの重心は、受け台２の受け凹部２２と地面とを結ぶ線に対して片側に位置して、バイブロハンマは回転軸１６を回転中心として、重心が存在する側で地面方向に回転して倒伏状態となり、回転軸１６を逆方向に回転して、起立状態と倒伏状態とが切り替わる。【選択図】図１
