A plurality of rows are provided in the part along the longitudinal direction. The device mounting rail A is manufactured as a long material such as aluminum or stainless steel, and is cut to a length corresponding to the purpose. In order to cover the end surface (cut surface), it is attached to the end B.

  Below, with reference to FIGS. 2-5, the shape of the edge part protection cap 1 of a present Example is demonstrated. In the following description, the side (front side in FIG. 2) facing the end surface H of the device mounting rail A in the state of mounting on the device mounting rail A (hereinafter also referred to as mounting state) is the end protection cap. 1 is a front side, and in the mounted state, the direction along the width direction of the device mounting rail A (left and right direction in FIG. 2) is described as the width direction (left and right direction) of the end protection cap 1.

  The end protection cap 1 of the present embodiment has a bilaterally symmetric shape, and includes an end surface protection plate portion 2, a horizontal top plate portion 3 extending from the end surface protection plate portion 2, and both sides of the top plate portion 3. And a pair of engaging claws 4 extending downward from the portion. The end protection cap 1 is a molded product made of a hard resin. The material of the end protection cap 1 is not particularly limited, and can be manufactured not only with engineering plastics (such as modified polyphenylene ether) but also with general-purpose plastics (such as polypropylene).

  The end surface protection plate portion 2 covers substantially the entire end surface H of the device mounting rail A in the mounted state, and prevents an operator, an electric device, or the like from touching the end surface H. On both side portions of the end surface protection plate portion 2, outer surface protection plate portions 7 are formed which extend to the front side and cover both lower sides of the device mounting rail A from the side. Moreover, the recessed part 8 is formed in the center part of the width direction in the front side of the end surface protection board part 2, and the center part of the width direction is the back side of the end surface protection board part 2 by the depth of the recessed part 8. Is bulging.

  The top plate portion 3 extends from the upper end portion of the end surface protection plate portion 2 to the front side, is attached to the horizontal upper surface of each linkage plate portion E in the mounted state, and is engaged at the end portion B of the device mounting rail A. It is comprised so that the outer edge F may be covered from upper direction. A semicircular cutout 10 that opens to the front side is formed at the center of the top plate 3 in the width direction. On both sides of the cutout 10, the end face protection plate 2, the top plate 3, A plate-shaped reinforcing rib 11 connected to the right angle is formed. The top plate portion 3 is slightly wider than the width of the device mounting rail A, and the engaging claws 4 extend downward from both ends of the top plate portion 3.

  The engaging claws 4 are hook-shaped protrusions extending downward from both side edges of the top plate portion 3, and the end protection cap 1 engages the engaging claws 4 on both sides with the engaging outer edges F on both sides, respectively. By doing so, it is attached to the end B of the device mounting rail A. It comprises a hanging portion 13 that hangs down from both sides of the top plate portion 3 and a tip portion 14 that extends inward from the lower edge of the hanging portion 13.

Each engaging claw 4 engaged with the outer edge F abuts the front end portion 14 against the lower surface of the engaging outer edge F, so that the end protection cap 1 is difficult to pull upward. In addition, in the mounted state, the engagement outer edge F is vertically clamped by the top plate portion 3 that adheres to the upper surface of the engagement outer edge F and the engagement claw 4 that contacts the lower surface of the engagement outer edge F. The protective cap 1 is held so as not to drop in the longitudinal direction of the device mounting rail A due to friction between the engaging outer edge F, the top plate portion 3 and the engaging claws 4.

  As described above, the end protection cap 1 according to the present embodiment has the engagement claws 4 on both sides engaged with the engagement outer edges F of the device mounting rail A, and between the top plate portion 3 and the engagement claws 4. By sandwiching each engagement outer edge F, it is mounted on the end B of the device mounting rail A. Here, since the engaging claws 4 on both sides have flexibility, they can be engaged with the engaging outer edge F from above the engaging outer edge F by a snap fit method. The end protection cap 1 can be attached to the end B of the device mounting rail A by a snap fit method. In the present embodiment, a notch 16 is formed between the engaging claw 4 and the end face protection plate 2, and the engagement claw 4 is separated from the end face protection plate 2 by the notch 16. The flexibility of the claws 4 is increased.

  When the end protection cap 1 is attached by the snap-fit method, first, one engagement claw 4 is placed on one engagement outer edge F as shown in FIGS. 6 (a) and 7 (a). The other engagement claw 4 is engaged with the other engagement outer edge F. The engagement between the other engagement claw 4 and the other engagement outer edge F is performed by sliding the end protection cap 1 in the width direction so that the engagement outer edge F is separated from the top plate portion 3 and the engagement claw 4. It can be easily achieved simply by inserting it into 15. Then, from this state, one engagement claw 4 is pressed onto one engagement outer edge F. As a result, as shown in FIG. 8A, the engaging claw 4 is deflected to the outside of the engaging outer edge F by the guiding action between the smooth lower surface 17 of the distal end portion 14 of the engaging claw 4 and the engaging outer edge F. Will be lost. When the distal end portion 14 of the bent engagement claw 4 reaches below the engagement outer edge F, as shown in FIG. 8B, the distal end portion 14 of the engagement claw 4 is engaged by the elastic force. Abutting on the lower surface of F, one engagement outer edge F and one engagement claw 4 are engaged. 6 (b) and 7 (b), the engaging claws 4 on both sides engage with the engaging outer edges F on both sides, and the engaging outer edges F on both sides are connected to the top plate portion 3 as shown in FIGS. It is clamped between the engaging claws 4 on both sides, and the end protection cap 1 is attached to the end B of the device mounting rail A.
