Abstract:
An air cleaner apparatus for a vehicle including fastening structure for fastening a first part and a second part by placing a first peripheral portion of the first part and a second peripheral portion of the second part one on top of the other and pressing the first peripheral portion and the second peripheral portion with a fastening part comprising:a first engaging portion provided with a first sliding contact surface on a second part side of the first peripheral portion of the first part, wherein the first sliding contact surface is facing the first peripheral portion of the first part and the second peripheral portion of the second part when the first peripheral portion and the second peripheral portion are placed one top of the other; a second engaging portion which engages with the first engaging portion when the second engaging portion is rotated in a fastening direction around a predetermined turning axis; a second sliding contact surface provided on the second engaging portion so as to be in contact with the first sliding contact surface in an engaged state of the fastening part with the first engaging portion, wherein pressing force applied from the first sliding contact surface increases as the fastening part is turned in the fastening direction around the predetermined turning axis; a pressing surface provided on the fastening part so as to press the second peripheral portion toward the first peripheral portion as the pressing force is applied; and an operating part provided with the fastening part at a predetermined interval from the predetermined turning axis for turning the second engaging portion against the first engaging portion, wherein the first part and the second part are intially held apart by intervention of a third part whose elastic modulus is lower than elastic modulus of the first peripheral portion and of the second peripheral portion, and wherein the first part and the second part are a case and a cap, respectively, of the cleaner apparatus, and the third part is a filter element sandwiched between the case and the cap.
