Claims

[Scope of utility model registration request]

A ratchet for independent rotation attached to a rotating shaft having a drill chuck at its tip and a ratchet for vibration rotation attached to a gear cover of a drive gear provided on the rotating shaft are coaxially provided, and the ratchet for independent rotation is attached to the A vibratory drill machine that switches from independent rotation of the drill to vibratory rotation of the drill by engaging with a vibrating rotary ratchet, comprising a compression spring between the singly rotating ratchet and the vibrating rotary ratchet, and a steel ball at the rear end. A switching member is provided which is capable of sliding laterally and has two stepped surfaces so as to cut and support the rotating shaft in the front and rear directions, and the switching member is supported by compression springs in two recesses provided in the switching member. A vibratory drill machine characterized in that the position of the lateral sliding is set by adapting a steel ball, and the position of the lateral sliding is switched between independent rotation of the drill and vibratory rotation of the drill.
