PROBLEM TO BE SOLVED: To provide a cover for load detection sensor capable of protecting a flexible board from an external foreign material during handling, transporting, and assembling into a vehicular seat.SOLUTION: A load detection device includes: a cover part (61) which faces a first main surface (51a) of a strain body (51); a side part (62) facing one side surface of the strain body; and holding parts(63, 64) which face a second main surface (51b) of the strain body, extending from a side part to a housing (53), and covering a gap between a load input member (52) and fixing members (55, 56), and holding the load detection sensor by cooperating with the cover part. The cover part includes: an opening (611) formed so as to correspond to a load input member; notches (612, 613) formed so as to correspond to the fixing member; and a projection part (614) projecting from an edge part of the opening and in contact with a part of the load detection sensor, and extending in the gap among the housing, the load input member, and the fixing member, and covering strain detection elements (57a, b) and the flexible board (58).
【課題】手扱い時、搬送時、車両用シートへの組付時、及び外部異物からフレキシブル基板を保護することの可能な荷重検出センサ用カバーを提供する。【解決手段】起歪体(51)の第1主表面(51a)に対向するカバー部(61)と、起歪体の一側面に対向する側部(62)と、起歪体の第2主表面(51b)に対向し、側部からハウジング(53)に向かって延在し、荷重入力部材(52)及び固定部材(55,56)の間の空隙を覆うとともに、カバー部と協働して荷重検出センサを挟持する挟持部(63,64)と、を備え、カバー部は、荷重入力部材に対応するように形成された開口部(611)と、固定部材に対応するように形成された切欠き(612,613)と、開口部の縁部から突出し、荷重検出センサの一部と接する突部(614)とを有し、ハウジング、荷重入力部材及び固定部材の間の空隙に延在し、歪検出素子(57a,b)及びフレキシブル基板(58)を覆う。【選択図】図7
