LIFTER ROTATION PREVENTING STRUCTURE |
摘要 |
A lifter rotation preventing structure includes a lifter body, a retainer and a biasing member. The lifter body is inserted into a sliding hole of a housing and reciprocated according to rotation of a cam. The lifter body has a peripheral wall slidable in a sliding hole and a partition wall partitioning an inside of the peripheral wall into a first space where the cam is located and a second space located opposite the first space. The retainer has a retainer body connected to an engaging member and a rotation preventing protrusion protruding from an outer periphery of the retainer body and fittingly extending through the peripheral wall. The rotation preventing protrusion has a distal end moved into a rotation preventing groove to prevent the lifter body from rotation. The biasing member interposed between the retainer body and the housing to bias the lifter body to the cam side. |

1. A lifter rotation preventing structure comprising:
a lifter body inserted into a sliding hole of a housing and reciprocated according to rotation of a cam, the lifter body having a peripheral wall slidable in the sliding hole and a partition wall partitioning an inside of the peripheral wall into a first space in which the cam is located and a second space located opposite the first space; a retainer disposed in the second space of the lifter body and having a retainer body located inside the peripheral wall and connected to an engaging member reciprocally displaced together with the lifter body, the retainer having a rotation preventing protrusion protruding from an outer periphery of the retainer body and fittingly extending through the peripheral wall, the rotation preventing protrusion having a distal end moved into a rotation preventing groove communicating with the sliding hole of the housing thereby to prevent the lifter body from rotation; and a biasing member disposed in the second space of the lifter body and interposed between the retainer body and the housing to bias the lifter body to the cam side. |
