The reinforcing member 285 is made of a metal material because it serves to support the ball 270. Preferably, the member 285 is a bearing steel, stainless steel, or a carbon hardened steel having a Rockwell hardness of 60 or more. The reinforcing member 285 may be inserted later after the reinforcing member inserting portion 280 is formed in each of the plates 210 and 220. It is also good to mold-inject each plate with the reinforcing member inserted from the beginning. If the reinforcing member is bearing steel or stainless steel, the physical properties of the reinforcing member are hardly changed even at the injection molding temperature. It is preferable to mold-inject each plate.

다음은 본 발명에 따른 선형이동 안내장치의 제조방법에 대해서 설명한다.먼 저,각 플레이트(210,220)가 공지의 방식으로 플라스틱 또는 수지물질로 성형사출 된다.성형사출된 각 플레이트의 보강부재 삽입부(280)에 보강부재(285)를 삽입한다(보강부재가 플레이트와 일체로 형성되는 경우는 이 과정이 생략된다).이후 적정한 갯수의 볼(270)을 무한궤도부에 삽입한다.다음에는,도8에 도시된 것처럼,각 플레이트(210,220)를 서로 마주 보도록 하여 짝을 맞추어서 체결홈(290)을 통해 볼트,너트 같은 체결장치로 양자를 체결하여 선형이동 안내장치(200)를 완성한다.The following describes a method for manufacturing a linear movement guide device according to the present invention. First, each plate 210, 220 is molded and molded into a plastic or resin material in a known manner. The reinforcing member 285 is inserted into the 280 (if the reinforcing member is integrally formed with the plate, this process is omitted). Then, an appropriate number of balls 270 are inserted into the endless track. As shown in Figure 8, each plate (210, 220) to face each other to match the pair through a fastening device such as bolts, nuts through a fastening groove 290 to complete the linear movement guide device 200.

본 발명에 의하면,선형이동 안내장치 자체는 사출성형한 플라스틱이나 수지로 만들고,무한궤도부의 부하궤도부에 금속재질의 보강부재를 삽입함으로써 선형이동 안내장치 대부분을 금속으로 제조하는 경우에 비해 그 제조원가가 대폭으로 감소된다.또한 그 구성이 간단하여 제조가 용이하다는 장점을 갖는다.특히 보강부재를 선형이동 안내장치 본체와 일체로 만드는 경우,그 구성이 더욱 간단해 진다는 장점을 갖는다.According to the present invention, the linear movement guide device itself is made of injection-molded plastic or resin, and the manufacturing cost of the linear movement guide device compared with the case of manufacturing most of the linear movement guide device by metal by inserting a reinforcing member made of metal into the load track portion of the endless track portion. In addition, it has the advantage that the configuration is simple and easy to manufacture. In particular, when the reinforcing member is integrated with the linear moving guide body, the configuration becomes simpler.
