Problems solved by technology

However, in this case, it is necessary to screw in a plurality of screws in order to fix the support member, and thus it may take a lot of work to fix the support member.
As a result, the effort to arrange the parking switching mechanism inside the casing may be increased.

Embodiment Construction

[0017] In the description below, the figure 1 The illustrated motor unit 1 of the present embodiment will be described by specifying the vertical direction based on the positional relationship when the motor unit 1 is mounted on a vehicle located on a horizontal road surface. In addition, an XYZ coordinate system is appropriately shown in the drawings as a three-dimensional orthogonal coordinate system. In the XYZ coordinate system, the Z-axis direction is a vertical direction in which the +Z side is the upper side and the −Z side is the lower side. The X-axis direction is a direction perpendicular to the Z-axis direction, and is the front-rear direction of the vehicle on which the motor unit 1 is mounted. In the present embodiment, the +X side is the front side of the vehicle, and the -X side is the rear side of the vehicle. The Y-axis direction is a direction perpendicular to the two directions of the X-axis direction and the Z-axis direction, and is the left-right directi...

Abstract

The invention provides a motor unit. The motor unit has a parking switching mechanism driven in accordance with a shift operation of a vehicle. The parking switching mechanism has a movable part whichmoves in a first direction in accordance with a shift operation of a vehicle; a parking lock arm which moves with the movement of the movable part; a support member that supports the movable member so as to be movable in the first direction. The support member has: a base portion; a through hole penetrating the base portion in the second direction; a positioning portion located radially outside the base portion in a radial direction centered on the central axis of the through hole; a contact portion which contacts the movable member and supports the movable member. The case has an internallythreaded hole into which a screw passing through the through hole is screwed. The positioning portion is in contact with a portion of the inner side surface of the housing that faces the center in thecircumferential direction.

Description

technical field [0001] The invention relates to motor units. Background technique [0002] A motor unit having a parking switching mechanism mounted on a vehicle is known. For example, Patent Document 1 describes a parking switching mechanism that switches using a shift-by-wire actuator. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2009-65742 [0004] The parking switching mechanism as described above may include a movable member that moves in response to a shift operation of the vehicle, and a support member that supports the movable member in a movable manner. In this case, the support member is fixed to the inside of the case housing the parking switching mechanism, for example, by a plurality of screws. However, in this case, it is necessary to screw in a plurality of screws in order to fix the support member, and thus it may take effort to fix the support member. Therefore, the labor of arranging the parking switching mechanism inside the casing may be ...
