To provide a shoulder adjuster device for a seat belt with excellent operability, the shoulder adjuster device comprising a release prevention mechanism and a mechanism to enable ascending of a slide member, the former mechanism preventing a release of engagement between a latch member and a latch hole, the latter mechanism enabling the ascending with engagement release prevention of the release prevention mechanism working.SOLUTION: In a shoulder adjuster device 1 for a seat belt, a latch member 80 is held by a slide member S so as to be movable in a vertical direction relative to a guide rail 10 and tiltable in a downward direction of a vehicle around a support shaft 81. Therefore, even though a release prevention mechanism is provided in which movement of the latch member 80 to release the engagement with a latch hole 12 is prevented in a state of the latch member 80 contacting a lower end portion 12r of the latch hole 12 and being engaged with the latch hole 12, when the slide member S is slid upwardly, the latch member 80 contacts the upper end portion 12f of the latch hole 12 and is tilted in the downward direction of the vehicle. Thereby, the engagement of the latch member 80 with the latch hole 12 can be released.SELECTED DRAWING: Figure 2

    【課題】ラッチ部材のラッチ孔との係合解除を防止する解除防止機構を備えると共に、該解除防止機構による係合解除防止が作用した状態で、スライド部材を上昇可能にする機構を備える、操作性に優れたシートベルト用ショルダアジャスタ装置を提供する。【解決手段】シートベルト用ショルダアジャスタ装置1では、ラッチ部材80は、ガイドレール10に対して垂直方向に移動可能、且つ支軸81回りに車両の下側方向に傾動可能に、スライド部材Sに保持されている。このため、ラッチ部材80が、ラッチ孔12の下端部12rに当接して、ラッチ孔12に係合された状態において、ラッチ部材80がラッチ孔12との係合を解除するように移動するのを防止する解除防止機構を備えた構成であっても、スライド部材Sを上方に摺動させたときには、ラッチ孔12の上端部12fに当接して車両の下側方向に傾くことで、該ラッチ孔12との係合を解除することができる。【選択図】図2
