When the engaging portion engages with the inner lever and the shift select shaft moves along in the axis line, the plurality of shift forks is rotated relative to the housing about the pair of supporting portions as a rotation center thereof and the sleeve connected to the pair of connecting portions is configured to be movable between the low speed side gear and the high speed side gear and the pair of supporting portions is provided at a point between a pair of reference fulcrums and the pair of connecting portions where a rotational moment of a connecting body formed by connecting the sleeve with the plurality of shift forks becomes zero at the pair of reference fulcrums.

Abstract: A transmission according to an embodiment includes a shift fork swingably supported by a case to move a movable element in an axial direction in accordance with the motion of a second shaft to two shift positions; two first protrusions provided on the second shaft and spaced apart from each other in the axial direction; and a second protrusion provided on the shift fork, and when the second shaft is in one of select positions, is positioned between the two first protrusions and overlaps with the first protrusions viewed from the axial direction. A protruding direction of the first protrusions and a protruding direction of the second protrusion are orthogonal to a swinging center of the shift fork when viewed in the axial direction. The second protrusion protrudes from the shift fork toward the swinging center. The second shaft is positioned between the second protrusion and the swinging center.

Abstract: An interlock mechanism includes a shift-and-select shaft a first fork, a second fork, a first inner lever, a second inner lever, an interlock member coaxially arranged around an outer circumference of the shift-and-select shaft while being allowed to rotate together with the shift-and-select shaft in the rotation direction as a unit and not allowed to be displaced in the axial direction, a first engagement portion formed on the first fork, a second engagement portion formed to project from the second fork, a first engaged portion formed to project from the inter lock member and engaged with the first engagement portion while the interlock member is positioned at a second rotation position and a second engaged portion formed on the interlock member and engaged with the second engagement portion while the interlock member is positioned at a first rotation position.

Abstract: Provided is a synchronization device for a manual transmission, which is capable of reducing an axial length of a hub sleeve. The synchronization device for a manual transmission includes a clutch hub, a hub sleeve, a gear piece, a synchronizer ring, and shifting key mechanisms. A synchronizer key of each of the shifting key mechanisms includes a key positioned in a circumferential direction with respect to the clutch hub and mounted in an axially and radially displaceable state, and a moving object mounted in a radially movable state into a radial mounting hole formed through the key and biased radially outward by a coil spring. A top portion of the moving object, which is projected radially outward from the mounting hole to engage with an inner circumferential surface of the hub sleeve, is formed into a shape having an engagement portion extending linearly in an axial direction.

Abstract: A gas generating composition for use in a pretensioner, which generates less CO gases and chlorine-containing gases after combustion and is superior in thermal stability and in producing and processing, is obtained. The gas generating composition for use in a pretensioner comprises a highly thermal stabilized binder, an oxidizing agent, and, if required, a chlorine-neutralizing agent as major ingredients. The gas generating composition can improve thermal stability of a gas generating agent, can reduce the amount of CO gases, is excellent in producing and processing, and can reduce chlorine-containing gases if required.
