Abstract: A casing structure of a vehicular power transmitting device, includes: a casing; a breather plug; and a stationary removal preventive member, wherein the breather plug includes an attaching portion and a body portion, the body portion of the breather plug including an abutting section which abuts on the removal preventive member when the attaching portion of the breather plug is moved relative to the communication hole in a direction toward the outside atmosphere. The removal preventive member is positioned relative to the communication hole such that the attaching portion of the breather plug is located to keep the breather plug in communication with the communication hole when the abutting section of the body portion comes into abutting contact with the removal preventive member.

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.
