Portable electric drill

To avoid entanglement when a vertical blind is opened and closed, an attachment member is secured to a lead carrier and engages with an operation shaft. The attachment member is composed of a body having a length half the width of the lead carrier, and a snap detent projects from one end of the body. The body is formed by cutting an upper part of a horizontal cylindrical member and opening outwardly the cut edges of the body. The attachment member is attached to the operation shaft from the underside in an oblique direction such that the body engages with the lower part of the operation shaft and the snap detent snap engages with the upper part of a short jaw. Even when rotary moment is applied to the lead carrier, the attachment member holding the operation shaft counteracts the rotary moment, thereby preventing the lead carrier from rotating.
