Abstract: A multiple throttle device of the invention employs a constitution in which, as a sensor section that detects the opening of throttle valves, a shaft member formed to have a different axis from a throttle shaft is positioned within the width L of a throttle body, and a throttle position sensor is disposed in the shaft member.

Abstract: A carburetor choke mechanism comprising: an actuator linearly expanded and contracted based on a temperature change; a connection lever which is connected to a rotation axis at one end, and rotates based on receiving a thrust of the actuator; a choke lever which is connected with the other end of the connection lever, and receives a rotatory force; and a valve shaft where a choke valve is fixed to one end thereof, and a valve shaft lever which receives a transfer of a rotatory force from the choke lever is provided on the other end thereof, wherein the choke lever has a bottomed cylindrical shape covering an outer circumference of the valve shaft lever, and the valve shaft penetrates a bottom thereof, and is provided rotatably, and a connection mechanism between the connection lever and the choke lever is provided inside a cylindrical outer periphery of the choke lever.

Abstract: An accelerator pedal apparatus includes, as a reaction force adding mechanism to add reaction force against pedaling force of an accelerator pedal, a rotation member which is rotatable relatively against a pedal arm, a locking mechanism which is capable of locking the rotation member when the accelerator pedal is at an arbitrary depression position, and an intermittent interlocking member which intermittently interlocks the rotation member with the pedal arm so that the rotation member is interlocked with the pedal arm when the locking mechanism is not in operation and reaction force is added against depressing operation of the accelerator pedal under operation of the locking mechanism while rotation of the pedal arm is allowed with release of interlocking of the rotation member and decrease or elimination of the reaction force owing to elastic deformation caused by pedaling force which overcomes the reaction force.

Abstract: An accelerator device capable of achieving miniaturization and easily varying torque characteristics with a simple structure. The accelerator device includes a housing, a grip-side rotary body which is rotated with accelerator operation, a friction member including a contact portion to apply resistance due to friction as being contacted to the grip-side rotary body, an urging member which is connected to the housing via the friction member and connected to the grip-side rotary body and which urges the grip-side rotary body to rotate to an initial position side, and a restriction portion which is arranged at the housing and which restricts rotation of the friction member with the urging force of the urging member as being contacted to the friction member. Here, the friction member is urged by the urging member in a direction that the contact portion is pressed to an outer circumferential face of the rotary body having the restriction portion as a fulcrum.
