Abstract: A detection device of the present invention is provided with: a housing; a circuit substrate disposed in the housing; a sensor which is electrically connected to the circuit substrate and detects information of an object to be measured; a connector terminal which is formed integrally with the circuit substrate and electrically connected to an external terminal; and a tubular connector which is formed integrally with the housing, surrounds a periphery of the connector terminal, and is fitted in the external connector. Through this configuration, the reduction in the number of components, the reduction in cost and weight, the simplification of structure, and other effects can be achieved.

Abstract: A throttle device includes a default mechanism. The default mechanism includes: a defining portion arranged on the body to define the default position; a first rotation body which rotates integrally with the valve shaft; a second rotation body which can rotate relative to the valve shaft and which engages with the defining portion to limit the rotation in a valve-closing direction; a first urging spring which is interposed between the first rotation body and the body and urges the first rotation body in the valve-closing direction; and a second urging spring which is interposed between the first rotation body and the second rotation body, and urges so as to draw the first rotation body in a valve-opening direction and draw the second rotation body in the valve-closing direction to engage the two with each other and to maintain the engagement during the non-operation of the drive source.

Abstract: A rotation angle detection device capable of obtaining a detection result in a wider angle range with high accuracy. The rotation angle detection device is provided with a part to be detected which is attached to a throttle shaft S by a rotor, and a Hall IC which detects magnetic flux components of the part to be detected. The Hall IC is provided with a magnetism collecting plate which is disposed facing the part to be detected and extends along the rotation surface of the part to be detected, and Hall elements which detect the magnetic flux components of the part to be detected, and output a signal corresponding to the rotation position of the throttle shaft S on the basis of the results of the detection by the Hall elements. The Hall elements each detect a magnetic flux component in an X-axis direction passing through the rotation axis of the throttle shaft S. The Hall elements each detect a magnetic flux component in the Y-axis direction passing through the rotation axis of the throttle shaft S.

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.

Abstract: An accelerator device for performing an acceleration operation includes a rotary body which rotates with rotation of a grip, a magnet which rotates with rotation of the rotary body, a rotation angle detector which detects a rotation angle of the magnet, an urging member which returns the grip to an original point position by urging the rotary body, and a separation member which separates the rotary body and the rotation angle detector, the rotation angle detector is fixed to the separation member and the rotary body is rotatably held thereby while the urging member urges the rotary body toward the separation member as well as in the rotation direction, so that positional variation of the rotation angle detector against the magnet can be prevented.
