PROBLEM TO BE SOLVED: To further improve a force for holding a housing to a circuit board.SOLUTION: A mounting part 20 inserted in a circular mounting hole 2 formed on a circuit board 1 is provided on a side face of a housing 10, and three insertion pieces are arranged at almost equal angle intervals in a circular plane shape. One insertion piece serves as a fixing piece 21 whose outer face 22A has an arc-like plane shape, and is formed by a first molding die K1 moving in an axial direction of the mounting part 20. The other two insertion pieces serve as elastic locking pieces 30 whose outer face 33A has an arc-like plane shape following an inner periphery of the mounting hole 2, that are provided with locking parts 37 locked with hole edges on a rear side of the mounting hole 2 at a tip of a piece body 31, and that can be elastically displaced, and are formed by second molding die K2 moving in a direction opposed to the fixing piece 21 of the mounting part 20. Extension parts 33 extending in a circumferential direction toward the fixing piece 21 are also formed at side edges of the pieces bodies 31 of the respective elastic locking pieces 30 isolated from each other by the first molding die K1. |
