Abstract

A vehicular rear wheel steering device (100) includes a housing (10), a rod (21) being non-turnable with respect to the housing (10) and movably supported in an axial direction of the rod (21), and a conversion mechanism (40) arranged between the rod (21) and the housing (10) to convert a rotation of a rotational drive device (30) to a drive force in the axial direction. The housing (10) includes a tubular first bush (51) disposed at a first end (10a) and a tubular second bush (52) at a second end (10b). Each bush (51, 52) is slidably engaged to an outer periphery of the rod (21) and supports the rod (21) to be movable in the axial direction. A rod supporting rigidity of the first bush (51) is lower compared to that of the second bush (52). The first bush (51) is arranged with an elastic body (51b) that deforms in a radial direction of the rod (21). The second bush (52) is arranged with an inner periphery protrusion (52a) at which the rod (21) tilts.

Description

technical field [0001] The present invention generally relates to a vehicle rear wheel steering device. Background technique [0002] A vehicle rear wheel steering device is disclosed in JP2009-113730A (hereinafter referred to as Patent Document 1). In the vehicle rear wheel steering device disclosed in Patent Document 1: at the spline structure of the conversion mechanism (which includes a spline protrusion formed on the link and a spline groove formed on the housing), the first link of the link The second end of the connecting rod is non-rotatable relative to the casing, but is supported movable in the axial direction; and the second end of the connecting rod is non-rotatable relative to the casing, but is supported movable axially through a predetermined gap in the radial direction of the connecting rod. [0003] In the vehicle rear wheel steering device disclosed in Patent Document 1, in addition to a predetermined gap defined in the radial direction of the connecting r...
