VEHICULAR MOUNTED PART AND ELECTRICAL WIRE WITH PROTECTOR

PROBLEM TO BE SOLVED: To reduce a power to be required when inserting an insertion side engaging part into a reception side engaging part.SOLUTION: A vehicular mounted part comprises: a first body part and a second body part (for example, a lib part 28 and a housing part 24) that can be combined with each other; an insertion side engagement part 30 that is disposed so as to project to the first body part; and a reception side engagement part 40 that is disposed in the second body part. A convex part 50 is formed in at least one part of at least one of an insertion side contacting part to which the reception side engagement part 40 contacts when inserting the insertion side engagement part 30 of insertion side engagement part 30 into the reception side engagement part 40 and a reception side contacting part to which the insertion side engagement part 30 contacts when inserting the insertion side engagement part 30 of reception side engagement part 40 is inserted to the reception side engagement part 40.SELECTED DRAWING: Figure 3 【課題】挿入側係止部を受側係止部に挿入する際に必要となる力をなるべく小さくすることを目的とする。【解決手段】車両搭載部品は、合体可能な第１本体部と第２本体部（例えば、蓋部２８と収容部２４）と、第１本体部に突出するように設けられた挿入側係止部３０と、第２本体部に設けられた受側係止部４０とを備える。挿入側係止部３０のうち挿入側係止部３０を受側係止部４０に挿入する際に受側係止部４０が接触する挿入側接触部分、及び、受側係止部４０のうち挿入側係止部３０を受側係止部４０に挿入する際に挿入側係止部３０が接触する受側接触部分、の少なくとも一方の少なくとも一部に凸部５０が形成されている。【選択図】図３
