A drive device includes: a rotor and a stator; a case housing the rotor and the stator; a brake rotor that is arranged on the outside of the case and rotates in conjunction with the rotation of the rotor; a brake caliper that stops the rotation of the brake rotor by coming in contact with the brake rotor; and a ventilation membrane that is attached to the case, stops fluid or solids from penetrating inside the case from outside the case and also has formed therein multiple pores that permit gas to flow between inside and outside. The case has an output part that supports the rotor and a stator holding part that supports the stator. The ventilation membrane is attached to the stator holding part.

Drive device and ventilation member

A holding member mounted to the case including the internal space, a holding member including the ventilation hole that provides ventilation between the internal space and the external space; a humidity-conditioning member provided midway in the ventilation hole of the holding member and absorbing water vapor; and a ventilation filter provided to the holding member, a ventilation filter being closer to the external space than the humidity-conditioning member is, a ventilation filter being permeable to a gas and preventing a liquid and a sold from entering the internal space.

Ventilation and humidity-conditioning unit and apparatus

A vehicle lampis provided with: a ventilating unitthat is provided with a first openingof a closed case, prevents entry of liquids and solids to an inside space S within the case, and allows circulation of air between the inside space S and an outside space of the vehicle lamp; and a dehumidifying unitthat is provided in a second openingof the casedifferent in position from the first openingand has an electrolysis dehumidifying element for discharging water vapor in the inside space S to the outside of the vehicle lampby electrolysis. Thus, a dehumidifying device and a lamp that can rapidly discharge water vapor that has entered the inside of a housing to the outside of the housing can be provided.
