Abstract: A vehicle seat that includes: a cushion frame rear portion that is rotatable around a rear portion shaft, whose axial direction is a seat transverse direction, with respect to a vehicle body floor portion; a cushion frame front portion that is connected to the cushion frame rear portion so as to be rotatable around a center fold shaft whose axial direction is the seat transverse direction and that is positioned further toward a seat front side than the rear portion shaft; a seatback frame that stands erect from a rear end side of the cushion frame rear portion; and a driving mechanism that moves the cushion frame front portion and the cushion frame rear portion relatively in a seat vertical direction between a non-reclining state and a reclining state, in which the cushion frame rear portion tilts downward and rearward with respect to the cushion frame front portion.

Abstract: A wire material for an elastic member includes: inner circumferential-side reinforced fibers that are wound in a spiral form; outer circumferential-side reinforced fibers that are provided on an outer circumference of the inner circumferential-side reinforced fibers; and thermosetting resin that is provided in at least a part of the inner circumferential-side reinforced fibers and the outer circumferential-side reinforced fibers and firmly fixes the reinforced fibers with each other. An angle formed by a winding direction of the inner circumferential-side reinforced fibers and a center axis of the winding is 70° to 110°. A winding direction of the outer circumferential-side reinforced fibers with respect to a center axis of the winding is along a direction of a tensile load applied to the wire material for the elastic member in accordance with a load applying torsional stress to the wire material for the elastic member as an externally applied load.

Abstract: A tensioner includes a power spring, and a backup member being in contact with the power spring and supporting the power spring by acting an urging force in a direction opposite to a radial shift of the power spring in a direction in which the power spring is wound. The power spring is unwound in a condition in which an inter-plate frictional force of the power spring is small in a case where an urging force acting from a power spring to a tension member is greater than a load acting from the tensioner arm to the power spring and the power spring is wound in a condition in which the inter-plate frictional force of the power spring is large in a case where the urging force acting from the power spring to the tension member is smaller than the load acting from the tension member to the power spring.

Abstract: The present invention provides a method of feeding an agent, capable of stabilizing a remaining agent of a feeding part in characteristic and amount just before definitively feeding an agent to each definitive portion. The method includes intermittently moving a feeding part to a plurality of definitive portions defined on a structural object to definitively feed a flowable agent with a predetermined amount to each one of the definitive portions. The structural object includes a semi-finished product part with the definitive portions and a frame to be separated from the semi-finished product part. The frame includes a waste portion for the flowable agent. The waste portion has a same form as the definitive portions. The feeding part wastefully feeds the flowable agent to the waste portion with a same amount as the predetermined amount and thereafter starts the intermittently moving for the definitively feeding of the flowable agent.
