Relay fixing structure
View Patent ↗Rib portions ( 87 ) have first rib portions ( 87 a ) which abut against outer portions, and second rib portions ( 87 h ) which abut against wail portions. They are formed in plural numbers over the entire circumference of an edge portion ( 82 ). Pressing portions ( 88 ) are disposed on a lid portion ( 81 ) so as to be opposed to a relay ( 2 ), and, in a state where engaging portions ( 67 ) and engaged portions ( 84 ) are engaged with each other, elastically deformed to press the relay ( 2 ) toward a bottom portion ( 61 ).
1. A relay fixing structure for fixing a relay which controls on/off states of an electric circuit, to a housing, comprising:
a housing base including a bottom portion on which the relay is to be placed, and a wall portion which surrounds an outer portion of the relay and erects from the bottom portion; and
a housing cover including a lid portion which covers the relay, and an edge portion which is suspended from a peripheral edge of the lid portion toward the wall portion of the housing base, wherein
the housing base is provided with an engaging portion which is engaged with the housing cover,
the housing cover is provided with an engaged portion which is configured to be engaged with the engaging portion, a rib portion which regulates movement of the relay, and a pressing portion which presses the relay and is elastically deformable,
the rib portion includes first rib portions which abut against the outer portion, and second rib portions which abut against the wall portion, the first rib portions and the second rib portions are formed in plural numbers over an entire circumference of the edge portion, and
the pressing portion is disposed on the lid portion so as to be opposed to the relay, and is elastically deformed to press the relay toward the bottom portion in a state where the engaging portion and the engaged portion are engaged with each other.
2. The reay fixing structure according to claim 1 , wherein
the relay includes a flange which is formed over an entire circumference by being projected from the outer portion located on a side of the bottom portion in a case where the relay is placed on the bottom portion, and
the flange interferes with the wall portion in a state where the relay is placed on the bottom portion.
