where “φ” denotes a rake angle, “α” denotes an inclination angle of the cutting edge 2 with respect to the rotation axis A, “β” denotes an angle between a feed direction of the cutting tool 1 and a direction orthogonal to a rotation axis A in a plane view of the cutting tool 1 and the work W, “r” denotes a radius of an outer circumferential surface of the work W before processing, and “r′” denotes the radius of the outer circumferential surface of the work W after processing.

Abrégé

A cutting tool 1 comprises a cutting edge 2, a cutting face 4 and a flank 5 and is used for cutting the surface of a rotating columnar or cylindrical workpiece W by skiving in which the cutting edge 2 is delivered to the workpiece W at an angle with respect to the rotation axis A of said workpiece W. When the rake angle is "φ," the angle of inclination of the cutting edge 2 with respect to the rotation axis A is "α," the angle formed by the cutting tool 1 feeding direction and the direction orthogonal to the rotation axis A when viewing the cutting tool 1 and the workpiece W in planar view is "β," the radius of the circumferential surface of the workpiece W before machining is "r," and the radius of the circumferential surface of the workpiece W after machining is "r'," tan-1(cosβ/cos(α−β) × tan-1(cos-1(r'/r)) < φ ≤ 90° is satisfied.

A small-sized door lock device capable of reliably preventing a key lever from operating into a lock direction when impact force is applied from a side of the vehicle. The door lock device has a housing (12) for receiving an operation mechanism (13) and having formed on it a support section (12f) for rotatably supporting a key lever mechanism (29). The key lever mechanism has a first engagement section (31) formed at a support end section (12f1) of the support section and also has a second engagement section (32) facing the support end section of the support section, rotatably supported by the support section, and engaging with the first engagement section to prevent rotation of the key lever mechanism in the lock direction. The key lever mechanism is adapted so that the first engagement section and the second engagement section are engaged with each other when the second engagement section moves in the direction to approach the support end section of the support section.

A door lock device for a vehicle includes an operating mechanism being selectable of a locked state where a latched state, between a latching member and a latched member, being unreleasable and an unlocked state where the latched state being releasable, an active lever being rotatable between a locked position and an unlocked position thereof, and an open link disabling a transmission of an operational force of a handle to the latched member under the locked state and allowing a transmission of the operational force of the handle to the latched member under the unlocked state. The active lever, provided with an elongated bore, is supported by a housing which houses the operating mechanism to be rotatable. The open link is operatively connected to the handle to be slidably supported by the housing and is provided with an engaging portion which engages with the elongated bore to be slidable therein.
