is a driving gear, 26 is a rotary plate, 28 is a pull string (pull operation member), 31 is a one-way clutch, 34 is a spring, 36 is a driven gear (the final stage gear of the gear mechanism)
, 38 is an engaging body, 51 is a filter, 53 is a take-up roller, and 54 is an engaged body.

Claims

[Scope of utility model registration request]

A filter is provided in the ventilation fan body so as to extend from one side of the front face of the ventilation fan body to the other side, and is adapted to be wound up by a winding roller disposed on the other side, and the filter is arranged to be wound up by a winding roller disposed on the other side. A rotary plate that includes a pull operation member hanging downward and is rotated in response to a pull operation of the pull operation member, and a one-way direction that transmits rotational force only in the pull operation direction of the rotor plate and the pull operation member. A gear mechanism connected via a clutch, a spring that applies a rotational force in the return direction to the rotary plate, an engaging body that is rotated by receiving the rotational force transmitted by the gear mechanism, and is engaged with the engaging body. and an engaged body that transmits rotational force to a take-up roller, and at least the engaging body is integrally molded to the final stage gear of the gear mechanism.
