Abstract: A belt element for a vehicular transmission belt is designed to be supported by the bands such that the head portion is located on an outer side of the bands. The base, head and connecting portions define two slots for engagement with the respective annular bands, and the base portion has an edge extending in its width direction. The edge includes a first edge located inwardly of widthwise ends of the head portion and functioning as a fulcrum of the belt element upon rocking of the belt element, and second edges located outwardly of the widthwise ends. The base portion has a smaller thickness on an inner side of the edge than on an outer side of the edge, and the second edges are located nearer to the head portion than the first edge.

Abstract: An actuator unit that drives a switching mechanism for a shift range of an automatic transmission is provided. The actuator unit includes a motor that generates a drive force for driving the switching mechanism, a control substrate that controls the motor, a connector that connects a wire to the control substrate, a housing that includes an opening, a cover that covers the opening, and a shock absorption material that includes a first shock absorption material and a second shock absorption material. The motor and the control substrate are positioned in a housing space defined by the housing and the cover. The control substrate is fixed to the housing. The first shock absorption material and the second shock absorption material are positioned between the control substrate and the cover, and contacts both the control substrate and the cover.

Abstract: A continuously variable transmission is provided with i) a primary pulley that is formed by a driving-side fixed sheave that is fixed to a drive shaft, a driving-side movable sheave, and a driving-side cylinder member, and has a driving-side cylinder, ii) a secondary pulley that is formed by a driven-side fixed sheave that is fixed to a driven shaft, a driven-side movable sheave, and a driven-side cylinder member, and has a driven-side cylinder, and iii) a drive belt. The drive shaft has a drive shaft internal fluid passage for supplying hydraulic fluid to the driving-side cylinder. A driving-side communicating fluid passage that communicates the drive shaft internal fluid passage with the driving-side cylinder is formed between the driving-side cylinder member and the driving-side movable sheave.

Abstract: A bearing structure includes a radial bearing for rotatably supporting an end of a rotary shaft while the rotary shaft receives a thrust load. The rotary shaft has an outer periphery. The bearing structure is characterized by comprising a rolling body supported in the radial direction of the rotary shaft within the bearing, a support portion for rotatably supporting the rolling body, an extended portion extending from the support portion toward the axial direction of the rotary shaft. The support portion is fit over an outer periphery of the rotary shaft. The extended portion is press-fitted over the outer periphery of the rotary shaft.

Abstract: A fixed sheave mounted on an input shaft and a movable sheave mounted on a cylindrical member that is slidably supported in the axial direction relative to the input shaft are respectively structured using annular members having the same shape. With this structure, the fixed sheave and the movable sheave can be common structural components, thereby enabling the structural components to be easily formed by making the shape thereof relatively simple. As a result, productivity can be further improved.

Abstract: A gear pump has a pump housing formed with a gear receiving recess, a pump cover coupled with the pump housing to cover the gear receiving recess, a hydraulic passage that uses the gear receiving recess as a passage part thereof, and annular inner and outer gears operatively installed in the gear receiving recess. The inner and outer gears are of a bevel type and meshed with each other in such a manner as to bias the inner gear in a direction to reduce the thickness of the passage part when the inner gear is rotated while turning the outer gear therearound.

Abstract: The position of a ball bearing (18) on a shaft (16) may be fixed, press fitting a sheave portion (10) onto the shaft (16) and sandwiching the ball bearing (18) between a flange (16a) and the sheave portion (10). Thus, the axial dimension of a stationary sheave half (4) for a continuously variable transmission may be reduced. Because one end (10c) of the sheave portion (10) is in contact with the ball bearing (18), thrust force from the sheave portion (10) is transmitted via the ball bearing (18) to the flange (16a), which will not loosen and, thereby, the structural integrity of the stationary sheave half (4) is maintained.

Abstract: A fixed sheave is formed by pressing fitting and integrating a sheave portion and a shaft that have been shaped separately. The shaft is formed in a stepwise manner, and has a bearing disposition portion at one end of the shaft and a sheave portion fixing section that has a diameter smaller than that of the bearing disposition portion, and that is on an opposite side of the step from the bearing disposition portion. The sheave portion is fixed to the sheave portion fixing section in abutment, against the step, with a rear surface of the sheave portion facing the one end of the shaft. A finish processing is performed to either or both of the sheave portion and the shaft after the fixing. A first bearing is inserted from the one end of the shaft and disposed at the bearing disposition portion after the finish processing.
