An opening/closing direction restriction mechanism for a manual shutter device and an opening/closing direction restriction mechanism for a suspended sliding door device. This opening/closing direction restriction mechanism is provided with: a flange fixedly mounted on a fixed shaft; a bracket which is loosely fitted to the fixed shaft and can be integrally rotated with a winding member; and a two-way clutch which can be switched between a reverse rotation inhibited state in which the revolution of a planetary external gear along a winding direction of the winding member is allowed and the revolution of the planetary external gear along an unwinding direction is inhibited, and a forward rotation inhibited state in which the revolution of the planetary external gear along the winding direction of the winding member is inhibited and the revolution of the planetary external gear along the unwinding direction is allowed.

Provided is a braking device configured to release a cord in a non-bent state so that the operation force required to pull cords is reduced and the behavior of slats is stabilized during an automatic fall, and a sunlight shielding device using the braking device. A braking device for braking movement of a cord includes a movement converter configured to convert movement of a cord into movement of another member. The movement converter includes sandwiching object configured to allow the cord to be sandwiched. The sandwiching object is configured to change a sandwiched state so that the cord is sandwiched by the sandwiching object when the cord and the sandwiching object move relatively in one direction and the cord is released in a non-bent state when the cord and the sandwiching object move relatively in another direction.

There is provided a hinge arm damper mechanism that reliably achieves a damper effect corresponding to a braking force of an elastic member. The hinge arm damper mechanism is configured to include a pinion gear, a pair of racks and, two sets of heavy load springs and, a pair of slide bars and, and a housing. The housing includes a box-shaped case and a plate-shaped cover. The case accommodates the pinion gear, the pair of racks and, the two sets of heavy load springs and, and the pair of slide bars and. A rotational torque applied to a hinge arm is transmitted to the racks and via a rotational motion of the pinion gear, and is converted into a linear motion of the racks and. The linear motion of the racks and is reliably braked by the respective springs and.

A reverse input lock clutch has a fitting portion of a spring stopper rotatably fitted in a cylindrical dent formed by being surrounded by an inner diameter portion on an end surface of an output member on a side opposite to a fixed member. A locking portion rotates with the fitting portion while having one end of a first elastic member locked by a holder groove. Adjustment of the rotation position of the lock portion with respect to the output member is made by rotating the fitting portion within a range of a groove length of an adjustment groove with respect to the output member and anchoring an adjustment pin at a desired rotation position to the adjustment pin fixing portion so as to fix the fitting portion on the output member.

A leakage detection device detects leakage in a PCV passage that at least includes a scavenging line that communicates between a crank chamber of an engine and a portion of an intake passage of the engine that is on a downstream side of a throttle valve and a fresh air line that communicates between the crank chamber and a portion of the intake passage that is on an upstream side of the throttle valve. The leakage detection device includes a pressure measurement, a first valve and a leakage determination unit. The pressure measurement unit measures pressure in the PCV passage. The first valve opens/closes the fresh air line. The leakage determination unit determines presence or absence of leakage in the PCV passage on a basis of the pressure in the PCV passage at a time when the first valve is closed.

A leakage detection device for detecting leakage in a positive crankcase ventilation (PCV) passage having at least a scavenging line and a fresh air line includes: a first pressure measurement unit that measures a pressure in the PCV passage; a leakage detection valve that opens and closes the fresh air line; a PCV valve that adjusts a flow rate of blow-by gas; a second pressure measurement unit that measures a pressure in the intake passage; a first valve controller that controls the leakage detection valve when a leakage diagnostic condition is satisfied; a second valve control unit that reduces an opening degree of the PCV valve, and suppresses a flow rate in the PCV passage based on the pressure in the intake manifold after the leakage detection valve is closed; and a leakage determination unit that determines whether leakage occurs based on the pressure in the PCV passage.

A fuel injection apparatus includes an injector that injects fuel into a combustion chamber or an intake port of an internal combustion engine; an injection amount controller that controls a fuel injection amount of the injector and corrects the fuel injection amount to increase when the internal combustion engine is in a given cold state; an air-fuel ratio detector that detects an air-fuel ratio of the internal combustion engine; and an air-fuel ratio rich fault determiner that determines an air-fuel ratio rich fault when the air-fuel ratio exists on a rich side than a predetermined determination value. The air-fuel ratio rich fault determiner shifts the predetermined determination value toward the rich side in accordance with the increasing correction of the fuel injection amount so as to correct the predetermined determination value.

The present invention provides a diagnostic apparatus for an evaporative emission control system which can accurately execute leak diagnosis under a stable condition. An ECU clocks a time tuntil the internal pressure value Pof the evaporative emission control system sealed at the negative pressure reaches the target internal pressure value P, sets the pressure change measuring time tbased on the clocking time t, and measures the pressure change amount Pwhich varies after the internal pressure value Pof the evaporative emission control system reaches the target internal pressure value Pfor a pressure change measuring time t. Then, the ECU sets the determination value Pbased at least on the spatial capacity of the evaporative emission control system, and determines whether the evaporative emission control system is normal or abnormal based on the pressure change amount P.

Diagnostic apparatus for evaporative emission control system

In a diagnostic apparatus for an evaporative emission control system having a fuel tank is hermetically sealed under negative pressure on the basis of target inner pressure, and leak of the evaporative emission control system is judged when a diagnosis value based on a pressure variation amount after the hermetical sealing under at least negative pressure is larger than a judgment value, ECU estimates an evaporated fuel generated amount on the basis of a tank inner pressure value at the start time of a diagnosis. When the evaporated fuel generated amount thus estimated is large, target inner pressure Pteb is set to a high value, and when the evaporated fuel generated amount thus estimated is small, the target inner pressure Pteb is set to a low value.
