An armrest device including a stationary shaft, fixed to a seat frame, an armrest bodyin which the stationary shaftis inserted and which is rotatable, a lock springmade of a coil spring tightly wound around the stationary shaft, with one end of the coil spring serving as a stationary-side hooklocked to the armrest body, and the other end of the coil spring serving as a free-side hookA hook-supporting partthat supports the free-side hooksuch that the free-side hookis raised in the axial direction of the stationary shaft, a hook-fitting partthat enlarges the diameter of the lock springby dropping the free-side hookon the hook-supporting partdownward in the axial direction of the stationary shaft, a platefor a hook, where the plateprojects from the armrest body, and a cam memberon the stationary shaft. The cam memberhaving (1) an unlocking cam partfor unlocking the lock springby dropping the free-side hookfrom the hook-supporting partinto the hook-fitting partwhen the armrest bodyis rotated in the armrest-accommodating direction, and (2) a relocking cam partfor locking the lock springby raising the free-side hookfrom the hook-fitting partand supporting it by the hook-supporting partwhen the armrest bodyis rotated in the armrest-use direction.

A roller shade comprising a spring-loaded retractor, a screen sheet having a trailing edge connected to the retractor, and a rod member attached to a leading edge of the screen sheet. The two ends of the rod member are guided by a pair of guide rails so that the rod member may be moved toward and away from the retractor by using a power drive unit in such a manner that the screen sheet may be paid out from the retractor and extended against the spring force acting on the retractor, and retracted or wound around the retractor, as desired. The rod member incorporates therein a telescopic structure which allows its length to be varied according to the change in the distance between the guide rails as the rod member is moved toward and away from the retractor. Thus, the roller shade can be adapted to windshields, windows or other openings having trapezoidal, curved or other non-rectangular shapes.

A fluidic apparatus includes a pulley driven by an engine, torque limiting means disposed in the pulley and adapted to shut off the transmission of driving force transmitted by the pulley when overload is applied thereto, and a driving shaft driven by the torque limiting means. The torque limiting means includes a boss formed coaxially with the pulley, a collar disposed integrally and coaxially with the driving shaft, and a coiled spring adapted to hold outer peripheral surfaces of the boss and the collar by tightening with a predetermined tightening allowance. With the torque limiting means, if abnormal loads should be applied to the driving shaft, there hardly occur internal breakages, or the like, in the fluidic apparatus. In addition, because the torque limiting means has such a simple construction, the fluidic apparatus is down-sized and reduced in manufacturing cost.

In a roller shade for an opening such as a rear windshield of an automobile, when the shade is full closed, the pull rod is intentionally bent so as to fully conform to the peripheral edge of the opening. The bending of the pull rod can be achieved either by an axial force which may be produced by gradually reducing the distance between a pair of guide members extending on either lateral side of the opening as the pull rod moves up or by a lateral force which may be produced by placing a slope on which the pull rod rides over as it reaches its final position for fully covering the opening. By controlling the bent shape of the pull rod in a suitable manner, it is possible to entirely cover the opening without leaving any uncovered gap.
