Claims

[Scope of utility model registration request]

A motor, a gear mechanism that transmits power from the motor, a gear cover that houses the gear mechanism, an angle head that houses the power transmission mechanism whose drive shaft and output shaft are rotated by 90 degrees, and a drive for the angle head. An angle drill in which both drive shafts are fitted with a coupling in order to transmit the power of the drive shaft discharged from the gear cover to the shaft, and the gear cover and the angle head are removably connected by a coupling sleeve whose inner diameter can be freely contracted. In the above, the coupling includes a coupling A having a flange portion and transmitting power to the drive shaft of the gear cover, and a bore portion closely contacting the flange portion of the coupling A and transmitting power to the drive shaft of the angle head. It consists of a couple ring B, a spring that applies a frictional force by restoring force to the contact portion between the couple ring B and the couple ring A, and a nut that adjusts the restoring force of the spring and is screwed onto the boss part of the couple ring B. A slip clutch mechanism for an angle drill, characterized in that the restoring force of the spring is adjusted by the rotational force of screwing the gear cover into the coupling B, and the power of the drive shaft of the gear cover is transmitted to the drive shaft of the angle head.
