Title:
VENTILATION DEVICE
Document Type and Number:
Japanese Patent JP2020008206
Kind Code:
A
Abstract:
To provide a ventilation device capable of easily assembling a temperature sensitive actuator.SOLUTION: A temperature sensitive actuator 4 includes an actuator body 4a, a movable cam 50, a spring 45 made of shape memory alloy and a bias spring 46, and the movable cam 50 is moved to a position for keeping balance between force of the spring 45 made of the shape memory alloy and the force of the bias spring 46 in accordance with an environmental temperature to perform automatic opening/closing control of an operation plate 2 in cooperation with a first cam follower part 22 of the operation plate 2 when the operation member 85 is located at an automatic control position. A second cam follower part 23 of the operation plate 2 and a fixed cam 3 cooperatively close the operation plate 2 due to sliding of the operation plate 2 when the operation member 85 is moved to a forcedly closing position. An engagement protrusion part of the actuator body 4A is fitted into a guide groove of a device body. When elastic claws 36, 66 of the actuator body 4A and the fixed cam 3 undergo snap fitting, the temperature sensitive actuator 4 is fixed to the device body.SELECTED DRAWING: Figure 3
