Abstract: An accelerator pedal apparatus includes a pedal arm which includes an accelerator pedal; a housing which supports the pedal arm between a rest position and a maximum depression position as being rotatable around a predetermined swing axis line; a first return spring which exerts urging force to the pedal arm to return toward the rest position; and a reaction force adding mechanism which adds reaction force opposed to tread force of the accelerator pedal. The reaction force adding mechanism includes a movable member movably arranged against the housing while receiving reaction force of the first return spring, a reaction force spring arranged between the movable member and the pedal arm to be capable of generating reaction force against the tread force, and a lock member capable of locking the movable member not to be movable at desired timing.

Abstract: 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.

Abstract: An accelerator pedal apparatus includes a pedal arm rotating around a first rotation axis line and having a contact portion, a return spring and a reaction force adding mechanism including a drive source and a rotation member rotating around a second rotation axis line in a state of being contacted to the contact portion which adds reaction force to return the pedal arm toward the rest position. A first distance from the contact position of the rotation member with the contact portion to the first rotation axis line is longer than a second distance to the second rotation axis line. The rotation member includes a contact section having the contact portion displaced while being contacted so that the contact portion is to be closer to the second rotation axis line when rotating toward the maximum depression position and to be farther from the second rotation axis line when rotating toward the rest position.

Abstract: A plurality of connecting blocks are mounted on a base plate. Each block has a base body and a vertical cylindrical portion formed on the base body, and has a vertical hole. The base body has a horizontal hole opened at both sides thereof and communicated with the vertical hole in the cylindrical portion. A plurality of intermediate blocks, each having a fixed portion and a pair of horizontal cylindrical inserting portions formed on both sides of the fixed portion are mounted on the base plate. The intermediate block has a horizontal gas passage having a pair of openings opened at upper surfaces on both sides of the fixed portion. The horizontal hole of each of the connecting blocks is engaged with the corresponding inserting portion of the intermediate block. A cylindrical connecting member having an inlet gas passage and an outlet gas passage is secured in the vertical hole of each connecting block.

Abstract: The present invention relates to an integrated gas control device in a high purity gas supply system for a semiconductor manufacturing apparatus in which a gas control line is made compact and gas control units are easily mounted or removed and a flow passage can be flexibly designed and a total lead time for manufacturing can be made shorter and parts can be easily replaced for changing the flow passage by using the standardized constitution parts. In the integrated gas control unit, the adjacent passage blocks are connected to each other with a metal gasket inserted therebetween such that a gas flowing-out passage communicates with the gas flowing-in passage and are mounted on a base plate along many gas supply control lines arranged in parallel. The body of the desired gas control unit such as an automatic diaphragm valve or the like which is constituted longitudinally is inserted into the mounting hole of each passage block with a gasket inserted therebetween.
