摘要:
A elastic member of weatherstrip has a base portion with nearly U-shaped section, lips extending from ends of the base portion. An edge of a door glass is adapted to be accommodated in an accommodating portion provided in the elastic member. Each of the inner wall of the accommodating portion, and the inner walls and the outer walls of the lips is covered with a surface treatment layer having a predetermined film thickness. In contrast, the outer wall of the base portion is not covered. An embossing for obtaining a surface like a pearskin-finished one with a surface irregularity is preliminarily performed on the outer wall of the base portion and the outer wall of each of the lips, so that the surface has gloss and color close to those of the surface treatment layer.

摘要:
An insert with a light weight per unit length, which is securely separable to obtain insert pieces, a method for producing such an insert, and a method for producing long products using such an insert. The insert includes a large number of insert pieces and joining parts formed by the application of a rolling operation and a tension force, and has a ladder-shaped configuration. Slits are defined between adjacent insert pieces, and include first slits, each having a large width in a longitudinal direction of the insert, and second slits, each having a width smaller than that of the first slits so as to be alternately formed. The joining parts include first joining parts, each having a small width in a width direction of the insert, and second joining parts, each having a width larger than that of the first joining parts so as to be alternately formed. The width ratio of the insert pieces, the first slits and the second slits in the longitudinal direction is determined to 100:(65˜104):(24˜53), whereas the width ratio of the first joining parts to the second joining parts in the width direction is determined to 20:(28˜33).
摘要:
An accelerator pedal apparatus includes a pedal arm rotating around a first rotation axis line, a return spring and a reaction force adding mechanism including a drive source and a rotation member rotating around a second rotation axis line and having a contact portion contacted to the pedal arm which adds reaction force in the direction to return the pedal arm to the rest position. A first distance from the contact position of the pedal arm with the contact portion to the first rotation axis line is longer than a second distance to the second rotation axis line. The pedal arm includes a contact section having the contact portion displaced while being contacted so that the contact portion is to be farther from the first rotation axis line when rotating toward the maximum depression position and to be closer to the first rotation axis line when rotating toward the rest position.
摘要:
An accelerator pedal device having a pedal arm working in conjunction with an accelerating pedal, a housing to rotatably support the pedal arm around a prescribed pivot axis line between a rest position and a maximum applied position, a hysteresis generation mechanism that comes in contact with the vicinity of an upper end of the pedal arm to generate hysteresis in a pedal force of the accelerator pedal, and an active control mechanism to push back the pedal arm toward the rest position under prescribed conditions between the pivot axis line and the hysteresis generation mechanism. The active control mechanism includes a drive source provided in the housing, and a return lever that is rotated in the same direction as the direction of the swinging of the pedal arm in conjunction with the drive source and is detachably engaged with the vicinity of the upper end of the pedal arm.
摘要:
A lubricant containing a compound of the formula (I) wherein n is substantially 2, 3 or 4, R is C1-4 fluoroalkyl and Rf is —CF2O(CF2CF2O)x(CF2O)yCF2— or —CF2CF2O(CF2CF2CF2O)zCF2CF2— in which x, y and z are each 0 or a positive real number to give a number average molecular weight of 500 to 2000 to a fluoropolyether of the formula HOCH2—Rf—CH2OH including said Rf, the fluoropolyether having a molecular weight distribution (PD, weight average molecular weight/number average molecular weight) of 1.0 to 1.5.
