Lamp unit mounting structure
View Patent ↗A lamp unit mounting structure includes a mounting panel having a mounting portion, a lamp unit, an elastic fixing member and a restricting member. The elastic fixing member is provided on the lamp unit, and includes a first portion which is extended from the lamp unit, a second portion which has a substantially U-shape, and has a first end being integrally connected to the first portion, a third portion which is extended from a second end of the second portion toward the lamp unit. The engagement portion engages the mounting portion of the mounting panel. The restricting member is provided on the lamp unit, and restricts a movement of the elastic fixing member in a mounting and dismounting direction of the engagement portion relative to the mounting panel. The restricting member has an escape portion which allows a movement of the elastic fixing member toward the lamp unit.
1. A lamp unit mounting structure, comprising:
a mounting panel, having a mounting portion;
a lamp unit;
an elastic fixing member, provided on the lamp unit, and including:
a first portion which is extended from the lamp unit;
a second portion which has a substantially U-shape, and has a first end being integrally connected to the first portion;
a third portion which is extended from a second end of the second portion toward the lamp unit; and
an engagement portion which engages the mounting portion of the mounting panel; and
a restricting member, provided on the lamp unit, and restricting a movement of the elastic fixing member in a mounting and dismounting direction of the engagement portion relative to the mounting panel, wherein:
the restricting member has an escape portion which allows a movement of the elastic fixing member toward the lamp unit.
2. The lamp unit mounting structure as set forth in claim 1 , wherein:
the third portion of the elastic fixing member is disposed in a first position when the engagement portion is not engaged with the mounting panel;
the third portion of the elastic fixing member is moved to a second position when the engagement portion is abutted against the mounting panel;
the third portion of the elastic fixing member is moved to the first position by elastic restoring force of the elastic fixing member after the engagement portion is engaged with the mounting panel;
the restricting member allows the movement of the elastic fixing member toward the lamp unit by the escape portion in the first position; and
the restricting member restricts the movement of the elastic fixing member in the mounting and dismounting direction in the second position.
3. The lamp unit mounting structure as set forth in claim 1 , wherein:
the third portion has an upper projection and a lower projection on each of both side faces thereof;
the restriction member has a retaining wall which is slidably fitted between the upper projection and the lower projection; and
the escape portion is provided between the retaining wall and the upper and lower projections.
4. The lamp unit mounting structure as set forth in claim 3 , wherein:
a projecting length of the upper projection is smaller than that of the lower projection; and
the escape portion is a notch formed in the retaining wall, which allows the upper projection to pass through the notch and which restricts the lower projection to pass through the notch.
5. The lamp unit mounting structure as set forth in claim 4 , wherein the retaining wall has a tapering portion disposed adjacent to the notch.
6. The lamp unit mounting structure as set forth in claim 3 , wherein the retaining wall is inclined.
