Abstract
A ventilation filter part 19 including a support body 27 and a ventilation filter 25 fixed to the support body 27 is disposed in a concave portion 44c in a stationary die 44. A movable die 40 is brought into close proximity to the stationary die 44 and these dies are clamped together. Resin is injected into a cavity CV defined therebetween as a result of the clamping to make the injected resin and the ventilation filter part 19 into one piece. A housing upper portion 13 (housing part) formed of the ventilation filter part 19 and the injected resin is thus molded.
