分に前記保持孔が配置された、ことを特徴としている。According to a third aspect of the present invention, there is provided the through anchor according to the second aspect, wherein the sliding member has a substantially arc-shaped cross-section as viewed from a side surface of the insertion hole and the circular member. A portion of the arc-shaped cross section on the upstream side in the webbing pull-out direction with respect to the insertion hole is formed to have an offset portion longer than a portion on the downstream side in the webbing pull-out direction, and is opposed to the main body portion on the upstream side in the webbing pull-out direction. Characterized in that the holding holes are arranged at the same time.

工程が簡素化され一層好適である。Further, since the holding hole for fixing the sliding member to the mold is arranged at a portion facing the main body on the upstream side in the webbing withdrawing direction of the sliding member having the arc-shaped cross section, the mold of the main body is formed. The mounting direction of the sliding member to the mold is the same as the mounting direction of the sliding member to the mold, and the sliding member is fixed to the mold at a position most protruding from the insertion hole forming surface on the upstream side in the webbing withdrawing direction. . For this reason, the mounting direction of the sliding member to the mold is perpendicular to the mold, and the sliding member can be stably fixed to the bottom of the mold, making automation of the through anchor manufacturing process easier. Becomes In particular, if the inner surface of the most protruding portion where the holding hole is arranged is configured to be held by the suction device or the like, the step of attaching the sliding member to the mold is simplified, which is more preferable.

好となる。Further, the webbing can be wound around the surface of the sliding member up to the most protruding holding hole arrangement portion on the upstream side in the webbing withdrawing direction. For this reason,
On the upstream side of the webbing withdrawal direction (usually on the side facing the inner wall of the vehicle where the winding device is arranged), the area where the webbing wound substantially parallel to the main body slides with the sliding member made of a low friction material is increased. In addition, the sliding property of the webbing is further improved.

易に挿通させることができる。If the offset portion of the sliding member extends over the entire length in the width direction of the insertion hole (the width direction of the webbing), the circumferential angle of the substantially arc-shaped cross section of the sliding member on the downstream side in the webbing withdrawing direction. Is small (there is no portion or small portion that overlaps with the periphery of the through hole in front view), so that the sliding member fixed to the mold can be more easily inserted into the through hole of the main body.

【００２７】このように、請求項３記載のスルーアンカ

2 is fixed to the piece 22 as in the prior art.
It is not necessary to provide a mounting portion (engaging groove) for mounting the main body 12 on the fixed die 32, and a complicated process of mounting the piece 22 to the main body 12 before fixing the main body 12 to the fixed mold 32 is required. This is omitted, and automation of the manufacturing process of the through anchor 10 becomes easy.

る。Since the holding hole 24 for fixing the piece 22 to the fixed mold 32 is disposed at a portion facing the main body 12, the mounting direction of the main body 12 to the fixed mold 32 and the fixing mold of the piece 22 are fixed. The mounting direction of the piece 22 is the same, and the piece 22 is fixed to the fixed mold 32 at a position (the position corresponding to the installation position of the fixing pin 40) of the vehicle body that protrudes most from the surface where the insertion hole 20 is formed. Therefore, the piece 22
The direction of attachment (fixation) to the fixed mold 32 is perpendicular to the mold, and the piece 22 is fixed to the mold groove 36 of the fixed mold 32.
It can be stably fixed to the bottom part (fixing pin 40), and the automation of the manufacturing process of the through anchor 10 becomes much easier.

１０の製造工程を自動化することができる。Further, since the piece 22 has an offset portion, and the portion of the piece 22 facing the main body portion 12 in which the holding hole 24 is arranged has no portion of the facing piece 22, it is shown in FIG. As described above, the piece 22 is fixed to the fixed mold 32 from the vertical direction with respect to the fixed
The piece 22 can be easily fixed to the fixed mold 32 by bringing the piece 22 closer to the fixed mold 32. Therefore, an apparatus for fixing the piece 22 to the fixed mold 32 can be simplified without using an expensive robot chuck or the like, and the manufacturing process of the through anchor 10 can be automated at low cost.
