Abstract: A case component of a transaxle includes: a bearing unit having a through-hole through with a shaft member is to be inserted; a matching surface unit having a matching surface on which another member is to be overlapped; bolt hole portions formed on the matching surface unit; bent wall portions, each having a V-shaped or U-shaped cross-section cut in a direction orthogonal to a straight line connecting a shaft center of the bearing unit and a shaft center of the bolt hole portions, each having a valley portion positioned on the straight line, and connecting the bearing unit and the respective bolt hole portions; and V-shaped portions, connected with the respective bent wall portions, provided on an outer circumference of the respective bolt hole portions, and protruding toward the bearing unit.

Abstract: An attachment structure for attaching a control component package unit to a transmission casing which accommodates a power transmitting mechanism of a vehicle and which is disposed in a drive-power-source compartment in a front section of the vehicle such that an axial direction of the power transmitting mechanism is parallel to a transverse direction of the vehicle. The control component package unit includes a container casing accommodating control components for controlling the vehicle. The attachment structure is configured to attach the control component package unit to a rear side part of an outer surface of the transmission casing, such that a straight line normal to the rear side part extends in a direction having a component of a rearward direction of the vehicle.

Abstract: In a vehicular power transmitting system, a fixing portion of a brake retaining portion receives a reaction force from a reverse drive brake and is located in a portion of a circumference of the brake retaining portion, which is outside a predetermined circumferential portion close to the shifting shaft support portion and is defined by a pair of lines tangent to a circumference of the shifting shaft and parallel to a straight line connecting first and second axes and located on opposite sides of the straight line, as seen in a plane normal to the first axis, where a forward/reverse switching device including the reverse drive brake is disposed on the first axis, and a gear type transmission is disposed on the first axis and the second axis and an outer housing wall and a partition wall radially inwardly extending from the outer housing wall are provided.

Abstract: In the helical gear, an opening perimeter wall includes a first arc side face located at the leading end side in the direction of rotation, concave towards the leading end side in the direction of rotation, and having a distance from the arc center as a first radius. The first arc side face includes a side face at a side of the rotation center of the hub, located at position with a distance from the arc center differing from the length of the first radius, on a verge of a virtual arcuate line centered about the rotation center, and passing through the arc center.

Abstract: As to a distance in a radial direction of a rotation shaft from a rim at the hub side to an outer peripheral side face, the outer peripheral side face includes a first side region having a distance located at the most leading end side spot in the direction of rotation of a helical gear longer than a distance at a tail end side spot.
