A nail driving machine for feeding materials, and a driving guide for a nail driving machine that guides a nose forming a nail shooting outlet to a driving position. [Prior art] In the past, nails were used to nail nails on floor boards, the tops of corrugated boards, the tops of outer walls, and the grooves of interior decoration materials. Position the nail at the nailing position, and insert a driving guide member suitable for the shape of the floor plate, wave plate, or groove into the front end of the nose of the nailing machine that forms the nail exit, and abut the guide members against each other. It is driven into the material, and the nail ejection part of the nailing machine is induced and positioned at the nailing position. The driving guide member is preferably based on the posture of the operator and the direction of extension of the driven material, such as floor boards. The installation direction can be rotated in any direction relative to the nose of the nailer. Those who cannot rotate, or because they are free to rotate so that they can rotate over the head irregularly, and cannot be positioned in the direction intended by the operator. In order to solve the above-mentioned problems, as shown in FIG. 5, it has been proposed that a contact arm 2 that can be slid along the nose is provided on the outer peripheral surface of the nose 1 that forms a nail ejection portion of the nailer, and is mounted on the front end of the contact arm 2. Scheme of driving guide 3. The above-mentioned driving guide 3 is formed into a hollow shape by cold rolling or the like, and the front end surface is formed into an arbitrary shape suitable for the material to be driven. A hole 4 is formed on the peripheral wall surface, and a steel ball 5 is accommodated in the hole 4 to drive the guide. An elastic ring 6 'is mounted on the outer peripheral surface of 3 to elastically press the steel ball 5, and the outer peripheral surface of the front end portion of the above-mentioned contact arm 2 is circumferentially divided by 5 312 / Invention Specification (Supplement) / 92-03 / 91136693 592909 at intervals of 90 degrees The recesses 7 are formed at a plurality of intervals, and the driving guide 3 is rotatably mounted on the contact arm 2. By fitting the steel balls 5 to the recesses 7 in order to obtain a "click" feeling in the direction of rotation, The direction of driving the guide 3 is changed, and at the same time, irregular rotation can be prevented to improve workability. [Summary of the Invention] (Problems to be Solved by the Invention) However, in the above-mentioned prior art, in order to receive the steel balls 5 on the peripheral wall of the hollow driving guide 3, the thickness of the peripheral wall needs to be a specified size, resulting in driving. The shape of the outer diameter of the guide itself is increased, and there is a problem that the volume of the front end portion of the nail ejection portion is increased, which hinders the workability. The present invention is to solve the above-mentioned conventional problems, and an object thereof is to provide a driving guide for a nailing machine that can easily visually confirm a driving position without increasing the outer diameter shape of the front end portion of the nail injection portion. (Means for Solving the Problem) In order to solve the above-mentioned problems of the prior art, the present invention includes: a nose portion forming a hollow nail ejection outlet; and slidably disposed in the nail ejection outlet of the nose, while compressing A driver for driving nails in the ejection port from the ejection port with driving force such as air; and a nailing machine for a contact mechanism that operates by contacting the material to be driven by protrudingly disposed in front of the nose, It is characterized in that a tip of the nose forming a continuous nail ejection outlet with the nail ejection outlet of the nose is mounted on the front end of the contact member constituting the contact mechanism, and a cylindrical driving guide is installed on the outer periphery of the nose tip. An annular groove is formed on the opposite peripheral wall between the tip of the nose and the driving guide, and an elastic ring is installed in the annular groove to keep the driving guide relative to the tip of the nose 6 312 / The invention specification (Supplement) / 92-03 / 91136693 592909 is detachable, and a recessed portion can be formed along the circumferential direction between the upper end surface of the driving guide and the lower end surface of the contact member. And convex. (Effects of the Invention) The steel ball for mounting on the peripheral wall of the driving guide is not accommodated, so that a thin peripheral wall can be formed. The overall diameter of the driving guide can be reduced, and the ejection portion of the nailing machine can be recognized. Good performance without compromising workability. In addition, instead of using steel balls, the recesses and projections between the contact member and the driving guide are elastically engaged by the action of the elastic ring, so that the irregular rotation of the driving guide can be prevented, and the The driving guide is maintained at the set position, and a "click" feeling can be obtained during the rotation operation to improve workability. In addition, since the driving guide can be produced by cutting from a pipe, and the elastic ring can use a general O-ring, it has a simple structure and can be produced at low cost. In addition, by removing the tip of the nose from the contact member, the removal operation can be easily performed when the nail is blocked by the ejection port.
